LED Upgrade to Rear Rectangular Lights

Look, I found this for you: http://www.nhtsa.gov/cars/problems/e...tml#EVALUATION

Now, obviously, if a light is right directly in your field of vision that's better than if it's up, down, or to the side. But the most important aspect of the third light is that it's different to your mind. And btw, those six LEDs will put out over 33,000mcd of luminous intensity.

OK, I read until the 2nd word where it said "Government", then I stopped.

You know, I have no idea what 33,000mcd of luminous intensity means? I have nothing to compare it against. Are you sure you don't mean an "MGD" as in beer?

BTW, you must also know that I really don't care, I'm just giving you a hard time. G-d bless you, if you want to experiment with a 3rd brake light. As long as you don't mind us REAL Cobra owners in The Registry laughing AT you.

It's Friday!

I know you are. It's part of our shtick.

Huh. He tends to know what he's doing, but every LED I have ever met ran cool. But here's a really thorough answer from, of all places, LED Magazine http://www.ledsmagazine.com/features/2/5/8 Lemmee tell you, I read some obscure crap, but nothing quite as obscure as LED Maagazine.

You outta get a job or something to occupy your time, if you're reading LED magazine. Oye vey.

Though it's probably a source of "enlightenment." But, maybe not in the same league as Buddha's Four Noble Truths.

Great banter, but to get back to LEDs....

is it possible to get an LED light that combines red/clear for the stop with an orange/yellow turn indicator? in the uk using a red turn indicator is illegal, but I still want to fit the rectangular lights. Of course I could fit >1 bulb to the unit, but it would be bodgy and messy.

(other cobra owners with the rect lights here have inserted an orange lens in the housing or run an extra seperate turn light, neither of which I am keen on doing)

Kevin, I know of no "dual color" LED automotive bulbs that would do what you want. I think what you would need to do is directly wire in LED PCB lights of both RED and AMBER in to the back of the rectangular fixture. Here is what I think would work: http://www.superbrightleds.com/cgi-b...%2Fpcblamp.htm Note that you would probably have to cut in and extend the wires if you couldn't fit it all in because the base can not be clipped off (it contains the driver circuit). But I don't know if an amber array of LEDs behind a red lens is going to look anything but red -- you'd have to test it out to be sure.

thanks, thats interesting.
I already bought a big amber LED that fits in the bulb holder. A quick test shows that it works, although the light is orange rather than amber!
i got the idea from an FFR article on doing this thats on the web somewhere, but i diodnt like their LED arrangement.
