audiofanaticz Posted November 6, 2011 Report Posted November 6, 2011 Are you having to use any resistors? if so what ones, if not why not? been curious on doing this for a long time now
Sanitarium Posted November 6, 2011 Report Posted November 6, 2011 i would assume that since he has so many of them in series that no resistors would be needed for a 12 volt setup
KenC210 Posted November 6, 2011 Report Posted November 6, 2011 Are you having to use any resistors? if so what ones, if not why not? been curious on doing this for a long time now wondering the same thing i didnt see any in the dome light pic Kids Cadi Power Wheel Build2007 Ford Escape Build2012 Toyota Corolla Build 2013 Toyota Tundra
audiofanaticz Posted November 6, 2011 Report Posted November 6, 2011 i would assume that since he has so many of them in series that no resistors would be needed for a 12 volt setup thats what Im thinking too, but even the pre-made led lights you buy for dome lights have resistors and what not. and my LED blinkers are resistor central! Maybe a link to the seller you bought them from, or more info on the leds?
killallblue Posted November 6, 2011 Report Posted November 6, 2011 looks good man i only have about 50 in my blazer
EclipseChris Posted November 6, 2011 Author Report Posted November 6, 2011 Well the are rated at 3.2-3.4v. In the first pic you can see me wiring them together in groups of 4 leds in series. That way each gets 3v if source is 12. Then i wire groups of them together in parallel so each leg of 4 gets 12v. No resistors, but like i said, there's 104 in my dome, so the total is always going to be divisible by 4 =P i resolve to be a nicer moderator. Tercel build R.I.P.

white4d96 Posted November 6, 2011 Report Posted November 6, 2011 I would highly recommend running resistors, and 12v Vregs with your LED's. A car power supply is very volatile, and it will kill led's, especially the cheap ones. I use 7812-style vregs, they each handle 1 amp of current and put out 12v steady. I buy them in packs of 5 from my local electronics supply store for $3. Too many projects, too little time...
EclipseChris Posted November 6, 2011 Author Report Posted November 6, 2011 Maybe a link to the seller you bought them from, or more info on the leds? Read what i wrote, it took 2 MONTHS for them to get here. Just hit up ebay and type in "leds". There's millions of em. i resolve to be a nicer moderator. Tercel build R.I.P.

EclipseChris Posted November 6, 2011 Author Report Posted November 6, 2011 "vregs" haha when nerds have swag. Yeah i prolly should, but its whatever. They work now and they are only on when the door is open, so i'm not stressin. i resolve to be a nicer moderator. Tercel build R.I.P. Eclipse build Old New V-Dub My feedback.

They work now and they are only on when the door is open, so i'm not stressin. bahaha! I did an LED dome light like 3 years ago and had that problem, hence my warning to you. After about 3 weeks I was dropping LED's like flies. Same with some Oznium strips I used for puddle lights. Using quality LED's also helps: I am working on a taillight retrofit using Philips LumiLED's, underdriven, and they are bright as heck (I made a test board with twelve of them and it's bright enough for a third brake light) I figure going a little conservative on the power and overkill on the LED count will make for a bulletproof setup (they are 70ma LED's and I'm driving them at 50) Too many projects, too little time...
