Brighter headlights?

Hey all! I drive a 1984 BMW 318i (that's the E30) with the standard H1 bulbs for the low and high beams (4 x H1 in total). I want better visibility at night and have been looking at options. Can anyone help with the following: 1. do i have to use high wattage bulbs to see a significant difference or would "upto 90% more light" 55W osram bulbs help? I would hate to spend the money on the 55W osrams only to end up with 5 extra lumens. 2. am i correct in saying that ALL xenon bulbs require the whole ballast and starter setup like fluorescents? are there some that don't? 3. Is there anyone who has used a high wattage bulb? what are your experiences? is the shorter life worth it? where on the continuum of wattage VS lifespan would you recommend? Right now I'm leaning towards the high wattage option, something like 80-100W. MY local hardware doesn't stock these and I doubt my local auto-electrical supplier would either. I'm thinking I may have to do some digging, maybe 4x4 accessory stores would have them since they are technically only meant for offroad use. K thanks, your help is much appreciated, I'll try to post an 'ible of old VS new and the installation procedure once I decide on the bulbs.

Headlight Restoration on the cheap.

How to restore your dull plastic headlamps to like new, for about $4.00 (if your lamps are dirty on the inside, that is a whole other instructable): Step 1 - Wash the headlamps with common dish soap and allow to dry thoroughly, this will remove the dirt and oils from the lamp. Step 2 - Using regular rubbing compound or silver polish (I used Silvo brand silver polish (about $4.00 a can here in Canada), it may work with copper polish as well) Apply a small amount of compound or polish using a soft cotton cloth (an old t-shirt or sheet cut into manageable size) gently rub the lamp in a circular motion (the amount of pressure is determined by the severity of the dullness, you may need to repeat the procedure more than once) allow the polish or rubbing compound to dry to a haze, usually by the time your done both lamps the first one will be ready to perform the next step. Step 3 - Using a clean dry cotton cloth buff the lens to remove all of the haze, if the lamp still looks dull repeat step 2. Step 4 - Once you are satisfied that the lenses are as polished as they will get, wax both lamps with a high quality auto wax, (a wax containing carnuba is the best) Mother's or Maguires works great. The wax will prevent bugs, dust and dirt from sticking to the lamp and it will retain it's clarity for a long time, if the lamp starts to look dull simply apply a new coat of wax. Step 5 - Stand back and admire your newly restored headlamps - you will be amazed at how much further you can see at night. *The attached photo is of my headlamp on my 1998 Suzuki Esteem - The before picture is from another 1998 Suzuki Esteem, my lamps were almost as bad as the one pictured here.

Motorcycle LED headlight bar

Wanted to make my own battery powered headlight for my dirtbike, I want to keep it in the 15x4 dimension. I would like to make it as bright as humanly possible in that dimension. Cost isnt that big of a deal just dont want to drop $300 on a pre fabbed one if I can make one for much less. A list would be nice, primarily LED's to use, battery, heat sink issues. Again I would like to build one that is really bright right in front and carries for a good distance. Any and all suggestions would be appreciated. Thanks.

Can I use arduino to control my high-powered bicycle headlight?

I'm in the midst of building a new high-power led headlight for my bicycle (i.e. Ive ordered a new battery and a bunch of hardware, led's and a driver).  My question for the community is whether or not an arduino unit could be used to control functions or modes of the light.  I have built alot of lights and know a decent amount about electronics but I have zero experience with arduino and programing.  I am using this buck driver ( with a triple cree xp-g led and a 14.4v lithium battery.  Ideally I would like a single button to cycle through 5 modes: off, low, high, F-U idiot driver, and strobe.  If anyone knows what kind of stuff I would need to buy(i.e. controller, switch,etc...), if the stuff would interface with this driver, and how I would go about programming the thing I would much appreciate it. Thank you, Patrick

Switching to LED lights for your car head lights - what you should know about it!

With LED technology getting cheaper and better almost weekly now it seems to make sense to use them in your old car.People who did it and post about it make the decisions even easier.I mean who wouldn't want to switch from pale yellow candle light to these bright white litghts showing you all in great detail?Problem is the firstly the legal side of things.Many countries now allow the use of LED replacements for many older cars - within limits.Where and if allowed it means you need to use LED systems that a compliant with your local road authorities and regulations.In a lot of countries though it is still not legal to replace incandescent head lights with LED ones.Why is this?If you read this after changing over already you will have noticed a destinct difference between the two types of "globes".The filament is very compact and in a H4 lamp the reflector is quite small and perfectly positioned as well.In comparison to (mostly the non-legal) LED replacements the light emitting surface is flat and usually a lot bigger than the filament.This means the light output and pattern changes as the reflector of your lamp is not designed to work with LED's and their bigger area of light surface.Being flat also means the LED can not really produce the same amount of light in LUX to the sides as compared to directly above.Most LED lamps compensate this with an added reflector in the front area.So we have two major problems:Not really enough light going sideways while too much light goes up and down in the LED system.Too much stray light due to the bigger surface are that puts out the light.Combined they result in light going into areas where it should not go, or not go at this level of brightness.The often used statement that now even highway signs are easy to read at night on low beam clearly highlights this problem.There is a good reason your head lamps should not shine upwards ;)What can be done to allow for the use of LED lamps in old cars?If not too old than your car already has H1/H7 lamps and indiviual for fog, low- and high- beam.For those it is now quite easy to get road legal LED replacements.Not so much though for the really old H4 systems with high- and low- beam in one lamp.Don't be fooled by your local auto shop though!Just because they might sell a lot of HID and LED lmaps does not mean what is on display for sale is actually road legal.If it does not state the corresponding certifications for your country/state than you can rest assured a cop on a bad day will have field day (or night) with you sooner or later.As said, in many countries there are now tested and legal option available.Their main difference to the cheap and uncertified ones is not their higher price alone.In comparison their more powerful LED's result in much smaller COBS -the LED strip giving the light.Reducing glare and providing a much closer match to the incanscent lamps.Why is it so hard to find a common ground and provide proper LED replacement systems?You might as well ask why you can buy a $20 amplifier or a $5.000 amplifier....When the first cars came out with LED lamps China saw the potential and provided all sorts of headlight lamps with LED's in them.Quickly they not only made it to the international markets but also gained interest for basically everyone wanting more light.Regulations were non existent back then...Even today it is next to impossible to actually provide proper numbers in terms of lumen, LUX or general brightness.What a LED provides can be quite different from what leaves the head lights.Old standards only refer to Watt, so it is no problem to find a cheap LED system that provides what a 100W lamp would get you at less than 30W on the input side...And the light color is not really specified at all in most countires.France required a yellowish light back in the day.A blue tint in your head lights was no problem with Xenon lights, so LED systems now go as high 7000 Kelvin, or close to a blueish light and as low as 3000 Kelvin or what is coming from incandescent lights.You see, finding a common ground is already hard just with the light output and color alone.There is only one real test that even today defines whether or not a head light needs adjustment or in case of LED replacements makes them illegal.The good old white wall with the markers, lines and distance mark on the floor.If you compare a properly adjusted head light on these test walls you get a very destinct pattern of light to see.Clear cut off's, brightly illuminated areas within the fields and lines and less bright areas in the outer regions - again still defined by the marks on the wall.Swapping to various types of LED replacements should provide the same patterns and brightness levels.In reality though almost all of them will only give you a very bright and undefined big area on the wall.No more dark areas with clear cut off to the bright middle section, even the formerly shadowish side areas are now well lit up.Great for you behind the wheel, bad for everyone coming the other direction, especially when wet and raining.Some people in the colder parts of the world will now what I mean when I say that some LED system will only give you good visibility when it snows if you turn them off ;)How to check for yourself if your new LED lights are any good for other people on the road?I assume you did the right thing and had your headlights checked and if required adjusted before actually putting LED lights in!Nothing is worse than trying to get more light if said lights are adjusted to point everywhere except the road.With your old light still in park in front on a straight wall on level ground, like your garage or any other wall you find.Park at a nice distance to get a clean pattern on the wall that is not too big.5 to 10 meters away should do fine.Use some painters tape or similar to mark out your desgined light pattern on the wall.Don't be too fancy, just some tape to indicate where bright light turn into way less on the wall and a few strips to indicate the cut off lines where patterns of brightness change on the wall.Leave the car where it is and put your new LED lights in.Check for yourself by how much the areas differ now.Anything above your marked cut off lines means you are blinding other drivers ahead of you.Anything way brighter than before on the sides could mean you also blind oncoming traffic on the other side of the road or freeway.A pale and low light level in these areas is not too bad and can be acceptable.Anything that clearly illuminates those formerly dark areas however should not be used on the roads.Another check is to try at what distance your old low- and high- beam start to become a bit too birght too directly look in to when you stand in front of your car during a really dark night.Look somwhere drak and move closer until you reach the discomfort zone.With your LED lights you should be able to get as close as before ...

1970 Honda CT70 LED Headlight & USB charger idea

Hi guys, New here but not to projects and tinkering in general. Mostly im a mechanical type guy and not to electrically inclined. I have a 1970 Honda CT70H Trail bike, I would like to replace the current headlight with a single or multipul LED set, also id like to split it and run a USB charger when the headlight is not runnning. My plan to acomplish this (my very simple in a perfect world plan) is to take the LED set from a small cheap flashlight that uses 4 batteries in order to get the proper voltage, and use the same leads the go to the headlight. Currently the Honda has a dimmer switch which I was planning on using for my switch between light and usb power. For the usb I was going to use a car cig-lighter type charger and but i know a car is a 12 volt system however i assume because usb chargers use 5volts that a car charger has a 5volt regulator in place? Included is a ct70 wiring diagram link, help would be great Thanks all

Im guessing im going to be working with 20A or so, and it will be charging a battery about the size of your average lawnmower battery. What rectifier should i get that can handle the amperage it would take too charge the battery? The engine already has a regulator, so i will just run the rectifier from the headlight wiring harness because it is getting the regulated 12v.

Need help solving a wiring problem...

Hi, I'm new here; hoping someone can help me with a problem I have &, over time, maybe I can help others. I've attached a diagram for the headlight circuit on a car I built.  The headlights work, but I've not been successful adding an LED to indicate whether they are in low beam or high beam and need to get that working. I have an RGB, common cathode LED and have wired it as shown in the picture.  It may be obvious to some of you with more electrical experience than me, but but instead of off; green for low beam; blue for high beam -- I'm getting off; green when I turn the headlights on; both green & blue when I flip to high beams; stays both green & blue when I flip back to low beams; goes off if I turn the headlights off. The one thing I found while trying to trouble shoot that I wasn't expecting is that the wires connected to the 87 pins on relays 2 & 3 show +12V.  That makes sense given the lights simply have a coil between the + & - sides but I wasn't expecting that -- not sure if I'm backfeeding 12V to ground [which might explain a couple of gremlins I've been chasing in other parts of my wiring system]. So, net, I have two questions: 1.  Is there anything wrong with the headlight circuit the way it is set up in the diagram? 2.  Why wouldn't the LED be lighting as expected vs. what I'm getting per above? Note - I didn't draw in the resistors required for the LEDs to work with 12V power, but I do have them on the LED.  Both the blue & green sides do light properly when I connect them directly to the battery to test. I appreciate any help you can offer! Thanks in advance.

So my short-term solution is to attach a temporary solar panel on it and leave the bike in the sun. I would plug it in and attach it when I was not riding so mounting it is not a problem. The panel needs to fit into a backpack and be fairly light (under 10 lbs).
