LED 3rd brake light? - SRT Forums

x-tatik · 11-02-2004, 05:06 PM

anyone do LED's in the 3rd brake light yet?

I'm trying to think of a way to do a row of 4 or 5 LED bulbs inside the 3rd brake light (I have a clear one)

anyone have any suggestions on what bulb to use, how to mount them, and how to wire them up?

I had 90 or so small LED's that i built a board for to put in a clear third but never got around to finishing it.

When I do I will post pics.

I'll get back on it soon. I need to cut up a stocker first!

Hey I need to get with you this week.

I got a project on the table, too. I'm using twenty 11,000mcd white LEDs I had around. I plan to use the stock red reflector, hence the white LEDs. I'll post picks when I get it all done.

Just 20

I was planning to put mine in a clear lense...mine are clear and shine red of course. I really plan to slam at least 75 very bright small LED's in there.

I know its overkill, but outrageous is how I like to be

Good luck, I wanna see yours when done. I'll post pics of mine too.

Sure. Like I said, the LEDs are 11,000mcd, so 20 of them should be around 220 candlepower. They are around 50 lumens per watt, so the array should be good for around 90 lumens. I figured this was a good balance between complexity and brightness.

I thought about using point-source or water-clear red LEDs, and may another day, but I don't have any handy. The first one is going to be done on perfboard, but I may make future iterations on a PCB. If anyone can hook me up with a full version of EAGLE, let me know

This project stemmed from my original desire to have a high-rate pulser for the 1st 1/2 sec that the 3rd brake light is lit. Motorcycles and commercial vehicles with LED tails have this feature. I have a circuit and PCB artwork ready to go but I'm gonna finish building the array first

so anyone get there projects done? I need a new bulb for my clear 3rd brake light and don't know which one to get?? 906/921?? I want an LED so it doesn't just burn the red off after 6 months like the one MPx sent me

jaymzx · 03-01-2005, 11:00 AM

Damn. This was back in November?

Sorry to say...no...I still have the LEDs on my breadboard lol. I was running the LEDs though a 2-day burn-in and then I kind of lost interest. I should fire the project back up when I have time.

I never did anything with this either......I decided to take the easy way out.....I've been looking for a right-angle replacement bulb but cant find any.
Anyone have a link for a 921 right-angle red LED??

thunder6g · 03-01-2005, 09:27 PM

anyone? I'd like to throw one of those in there and be done w/ the color burning off the cheap bulbs

cut up a third brake light

setup a board.

never soldered anything up. my friend who is gonna do the soldering called me tonight and wanted to work on it tonight, but I told him Monday.

We'll see how far I get.
