Helmet mounted bicycle light on the quick and cheap!

Helmet mounted bicycle light on the quick and cheap!
This is a quick and easy one.

A front bike light for your helmet, it goes where you go and shines where you look! No more multiple handlebar mounts on different bikes, broken handlebar mounts, cumbersome external batteries, etc.

After breaking several cheap plastic mounts I'd had enough of bike mounted lights. Enough I say! Why can't mfg's make fiber reinforced mounts!

Having used headlamps extensively for camping and hiking I decided it was time for a helmet mounted light that I could point where I wanted, especially in driver's eyes to alert them of my presence.

Let's begin...

Step 1Acquire LED flashlight

Acquire LED flashlight
Rather than buying some underpowered (or overpriced but bright) off the shelf solution with a big external battery I hit up Sams Club for a two pack of aluminum bodied 3W pocket sized LED flashlights. $28 for two was a good price IMO. Sam's Club Lights.

These run on 3 AAA batteries which are small and easy to store spares in your bike kit somewhere.

There are plenty of resources for LED flashlights of all sizes, prices and brightnesses. Google is your friend.

I have used a similar method of attaching my flashlight to my helmet for years. I use heavy rubber band though. It holds steady and is fairly easy to remove. I like the adjustability of a rubber band too. As far as problems with a helmet mounted light; I have had none.

Holy hell, I thought the exact same thing before I even read it...the more you read, the more idiotic this all seems. NOT even an instrucional article, in any way @ all. Frickin' ridiculous.

First of all...DUDE! This is a great idea and a great Instructable!! Secondly, I'm not sure about the safety of this thing. Although the flashlight is less than a half pound, it still throws off your head balance just a little. Sure you will develop the neck muscles to compensate so I'm less concerned about that than this...The real problem is you've added a big metal thing to the outside of the helmet. If you happen to need the helmet to protect your brains, I'm thinking the flashlight will survive intact while the helmet will break open instantly right where the light is mounted. If only the flashlight was made from soft plastic I would be still more excited about the idea. Maybe you could disassemble the flashlight and mount, say, the bulb in front, batteries on the side, and switch somewhere convenient. Just an idea. I still like the idea of mounting the light to the handlebars. Check out any of the many Instructables on that topic and see if you can come up with something that won't break under rough conditions. And lastly, I really like that little Sam's Club flashlight. I have five and counting. All of my friends are getting a Sam's Club LED flashlight for Christmas. They are extremely bright, sturdy, and use cheap batteries. They are easily the best lights on the market anywhere near $14. The gearhead flashlight-a-holics don't like them because there's no electronics to control the bulb, but that always raises the price by $50 to $100. What's interesting is that for a $200 light with the same performance, they love them, but this one they don't.

mag lites own. i have a... 3d cell blue and 2 cell AA blue and they have both worked, surprisingly, well. the only lights i have seen firsthand to beat them are my friends. but they dont count causehe makes them himself. theyre like those lights on helicoptors in the movies that go a mile in fog (im not joking whatsoever) only his are in a convenient (not really) falshlight. me and most of my troop (boy scouts) have magltes and have had for multiple years and they survive the rigors of camping and do not die oftem even under avuse. (i threw up on my friends one time) the only downside is they are like 80% machined aluminum or something and the large ones are a bit heavy. i am totally gonna do this. but not soon cause i dont think itll hold a 3dcell maglite ountain biking, which i am next weekend. i am mountain biking, not a 3d cell maglite. lol

I second that Maglites are awesome. I lost one in my yard at the beginning of winter and found it when the snow melted the next year. It probably sat there three or four months. When I found it I twisted the head and it turned right on. Also, the aluminum isn't what makes the larger ones heavy, its the batteries. Aluminum is a little heavier than plastic though...

I did pretty much the same thing, but with a couple differences. First, I used lights from Home Depot. The bodies are plastic (lightweight). They use 3 AAA batteries, like yours, and have 5 LEDs. I mounted 2 of them on my helmet, with spacers in between. The spacer at the front is wider, so the lights angle outward slightly, covering a wider area. That's the primary reason for having 2 lights. The other is that if one goes out, I still have plenty of light to get me out of the woods, without having to stop and change batteries. I carry spares regardless, but I ride with a couple other guys, and I don't want to stop the group if my batteries die. Great instructable, very helpful to those on a limited budget!

Not my quote, but something to think about.

"The first and most important rule for mounting a light on your helmet is that it must break away readily when you crash or catch an overhanging obstacle. If it does not, you risk having your neck jerked when it snags on the pavement or tree. Besides jerking your neck, that can add to the g's of the shock to your brain when you hit pavement. "

Firstly I think that a really good idea, so I had a look around to see if there was something like that out there and you can actually buy a proper helmet with a built in front light and 3 red led lights at the back of the helmet at htpp://www.unijem.co.uk So just thought I would share this info as I am buying mine from there.
