I am trying to change all the led's in my third brake light. I have a spare one but they are very dim and want to change all the leds to make it brighter. Can anyone recomend new led's and what resistors to use with them, I want it really bright but don't want to pay $5 an led. Anyone interested in a project? I'll supply everything you need, thanks, CHRIS........

No help out there? :confused: :huh:

Here is a place you can start

I've been gathering supplies to convert all of my tail lights to LED.
I was going to just use the spoiler brake light, and disconnect the window light though.

THere's plenty of bright LEDs out there. I got mine on eBay from a seller called "oemsupport". Good service, cheap price.

These LEDs seem to fit my purpose well:
615nm (reddish-orange)
12,000mcd @20mA
5mm

I picked up 100 for $17.00.

The tough part has proven to be maintaining the original resistance in order to get them to flash properly with the original blinker. This is not an issue with the brake light, but since the LEDs draw such low current, your car may be fooled into thinking that you have a bulb burnt out.

BUMP

do a search for member name "basshead" and the tail light conversion to LED. This'l give you an idea of what you're up against.

I've been down this road before with switching all of the bulbs over on my old Dubb. This is exactly what you need to fix the voltage issues when working with LED's for turn signals:

This resistor kit simulates an approximate 2 Amp load (like incandescent turn signal bulbs) so your signals will flash properly.

Sorry to revive an old, dead post, but this could be useful information for others looking to do a sweet LED transition.
