hello pff, as i wait for money to roll in so i can finish my engine, i decided to tweak on my tail light idea. i have finished the stop light portion of the board, mocked up the turn signal board, and have some ideas for the tail light portion. but for now i'll show you the stop light, keep in mind this is tinted too, so its normally completely black, and these are as bright if not slightly brighter than the old bulbs.
i used 20,000 lumen, or however they are measured. i might go for a higher brightness when i go for the notchback ones.
4 bulbs, with a 100 ohm resistor, and like 27 of them across. i forget the amp for them, but i got some voltage regulators that were rated for 1.5, and i remember thinking that was enough for each circuit. even though i ended up not using them >_> they are 20,000 MCD

Hmmm cool. Thanks. Nice work BTW. I'm all bout them LED's.

Did you get the LEDs off ebay as well? That's significantly cheaper then I've heard people source them before. Have you considered marketing these? I would be interested

I suggest you do more research... LM317 works in voltage OR current regulation. You get much better result using them.

Thanks ogre, that would be nice! And yeah the thought of selling these did cross my mimd, but I want to see how they stand up to the test of time. Im only doing the tail, stop and turn for now because I dont have reverse lights (tr anny swap before I owned it). These are pretty labor intensive, and I would need the lenses send to me to keep costs down.
edit: yeah i got the bulbs off ebay too. i hope they last, they were on par with what you payed, around $0.08 per led

I've been reading up on vibration issues and LED's. Also theres some discussion on how all LED's are NOT created equally. Some loose their brightness rather quickly, some fail quickly. Guess time will tell.
Edit... solder much? What type solder you using? How are you planning on keeping moisture away? I've read that using things like rubber cement will work, dunno.

Well I was going to use some rtv to cover the back of the board, and use some of that goop that seals the tail light to seal the edges where they meet the lens. The vibration thing has me worried too. We will see how my set holds up >_> Edit: quick search says they are naturally pretty vibration resistant.
