Car Door Warning Color

Car Door Warning Color

  • Danger.jpg
  • closed-opening.jpg
This is a simple 'Ible about using color to increase automobile safety.

Where I live, traffic is dense. We have a plethora of motorized vehicles in a relatively small area, from big trucks on down to scooters. We have a lot of narrow streets and alleys too. Also, here in Taiwan we enjoy a high percentage of motorcycle and scooter ownership. It used to be highest in the world, and may still be. Scooters and motorcycles are often streaming past cars, whether those cars are parked, standing, or under way. It is dangerous when a car door opens and oncoming traffic, either two- or four-wheeled, does not have enough warning.

I am particularly sensitive to this problem since a slight incident that happened a few years back. It was about 8:30 one rainy morning. I was riding my motorcycle on the way to work, and approaching a red light. Everything was a bit blurry because of the rain on my visor. Legally and in accord with local practice, I was passing to the right of the waiting cars when the right back door of one opened suddenly! The front of my cycle hit it and glanced off at an angle, but I didn't go down. A schoolgirl got out and seemed quite concerned that the car door had sustained no damage. That was annoying. What about me? Someone in the car was scolding her. But I didn't say anything and neither did she. Car door was okay, motorcycle was okay, she shut the door and walked, the light changed, and we all went our separate ways.

I've had two or three cars since then, and now I like to paint the door edges a bright, contrasting color so it is obvious to approaching traffic when a door is opening. As it happened, I painted another set of doors yesterday, and took some photos.

It's a wonder that auto mfgr's haven't thought of this.

Very good idea, milesfromneihu. Motorcyclist-awareness is something 4-wheeled drivers in my area lack. Lots of crashes and fatalities. Though my town has very little street parking, ya never know where ya might go. Definitely keeping this 'ible idea in mind.

very smart, I love it 10/10 as a cyclist I think this should be standard on all cars, well done.

Way to go with a simple solution.
Consider adding a step in the beginning to lightly sand the original car paint. Eventually, the spray paint should peel and flake without a roughed surface to adhere to. A cheap paint job (whole body/touch up) sometimes doesn't use a primer coat for paint adherence and instead relies on light sanding of the original paint. Most spray paints, purposes for vehicle coloring or not, will flake with time.

You realise, when your door is fully opened, people will be like" why in the world is it orange?!" But, screw what they think. This practical! On another hand, you could also put reflective tape so that it's also visible at night. But still, this is a great idea! and without this i'bles i wouldnt even think about reflective tape.

Why are people underwear strange colors? Because it is private. Door should be closed unless exchange of people.

There are a lot of bright colored fluorescent paints available. Why not use them?
Feb 10, 2012. 6:42 PMapender says:
This is a good idea. Having the warning indicated so professionally and distinctly might decrease the time necessary to leave the door open to alert oncoming. So it saves time and guilty consciences by saving events for the video games environments and not where you have things to do.

You can probably find retroreflective beads (the stuff they add to crosswalks and traffic lane stripes) to add to your paint when it is wet, but applying that to anything other than a horizontal surface might be difficult. Tape might be easier. The reflective strips used on life jackets might be a good choice - check your sporting goods/boating supply store.

I had a car that had red lights on the door that turned on when you opened it, but if I had that now I'd add a switch - sometimes you don't want your lights coming on when you open a door.

I agree though, for visibility, a combination of 1)contrasting color, 2)reflective material, and 3) LEDs would be best.

Just make sure your LEDs are noticeable (pulse or strobe them?) and make sure your lighting color scheme doesn't conflict with traffic laws (if it is red, it resembles a brake light, blue and green are often restricted to emergency vehicles).

You can find conpicuancy tape just at just about any truck stop and/or RV supply center.
Feb 11, 2012. 6:27 PMgeorion says:
you can "throw" the beads,have something to catch the ones that dont adhere to the paint and keep reusing them--actually all other ideas are "cheaper"

good idea but not perfect doing.

Older Rolls Royces had reflectors, kind like this. The same idea non the less.

This should be standard on all cars. Great Idea, go make some money with it.

Such a simple idea. Made me facepalm for not thinking of it. Commendations upon thee.

ME TOO!!! :)

It's a pretty good idea, Although I'd consider reflective tape. But hey, you made bikesnobnyc's blog too!
Feb 9, 2012. 6:01 PMBlaise_Gauba says:
Very SMART idea! Thank you! I live in Los Angeles and there is a LOT of traffic here and a lot of crazy drivers too boot! I'm going to do that. ~Peace

You can buy self sticking tape with embedded LEDs for about $20. Enough to do a couple of doors. They're very bright, you can select your color, and they also provide illumination at night when the door is open or ajar. They run at 12-15v, just right to wire into the door switch. Mine come on when the door opens 1/4 inch. Because they're self contained, no electronics knowledge is necessary and they're waterproof enough that weather and car washes don't bother them. An added advantage is, if you ever sell the car and the new owner doesn't like them, they can be removed without damaging the finish, the excess adhesive removable with a little GooGone. The LED strips are available from many online electrical supply and electric surplus stores. Cut them between the LEDs with scissors to fit them. Easy Peasy.

Very interesting ideas, both painting and leds, but...
I am not sure if there is space enough in my car.
I've seen a kind of led stripes with different colours (blue, white, red,...) even I have some to put inside, roof and floor, under seats, killing blind zones (some day, promissed...)
Are you sure they are brilliant enough?
Could you tell the place or better a site to acquire?
It would be perfect to compare with mine

Tks

they will definately be enough at night, but during the day is the problem. i have seen led light strips that work equally well in the day as night.
Feb 15, 2012. 10:34 PMmeenzal says:
You want to make sure that you get "high intensity" LEDs. The regular ones would be a bit lacking.

I found this link: http://www.oznium.com/led-flex-strips. The website specializes in these LED products.
Feb 15, 2012. 10:56 PMsokamiwohali says:
i didnt even know they made HI led light strips. the only ones i have ever seen was at walmart!!...lol :)
Feb 16, 2012. 12:09 AMmeenzal says:
I just found this company too: http://www.ledwholesalers.com/store
Their stuff is also available at Amazon, which is where I found them.

I happened to get the ones I used from West Florida Components about a year ago. They were sold as Ultra Bright LED strips. Sadly, I just looked at they are not available there now. But do a search on "ultra bright LED strips" and I suspect that you will find a source.

The strips I have are very low profile and fit with room to spare. They are very brilliant and visible in daylight as well as night.

This is not to say LEDs are a better solution --the author of this 'ible has a great idea that's easy to do. This is just another idea, like reflective hazard tape. Maybe to be safe, paint the area, apply reflective tape, and put LEDs on top. :-)

By the way, in case an accident does occur, I suspect an insurance company would look fondly on this as demonstrating the car owner tried their best to avoid problems.

They changed names of pics... where you can see meassures and prices.

1st- 1,20m 12V 2700-3500K = 10,20€
2nd- 5,00m 12V 3500K= 3570€
3rd- unknown

Great idea! Most cars have reflectors just inside the door on the inside panel. But, this is much more visible during the day. I think masking the inner panel and the outside of your door might make it look cleaner though. But, if you are a pure functionalist, then what the hell—just mask the seal.
Feb 7, 2012. 1:57 PMNatureGeek24 says:
Great idea, but a reflective neon yellow may be a better color choice. Easier to see at night, and "pops" a little more than orange for those who are chromatically challenged.

(My husband didn't like red-green deficient, the dog is color blind, so we created chromatically challenged. :)
