I replaced the bulbs that burnt out in my hazard light and defrost switch that illuminates when the headlights are turned on, I was going to replace just the bulb with the microbulbs you can get in radioshack like the other DIY's , but then I found these:

Whats nice is that the base is included so you dont have to fiddle with the wires on the LED. the base was a tight fit but I managed to push them in and twist them to lock; the results and the pics of the bulb+base below:

 

I've been all about superbrightLEDs.com for a while now. Good products, good service, good support, and I've never had a problem with their shipping either.

 

yup I like their cheap and fast USPS 1st class shipping ! browsing their catalogue makes me tempted to replace every bulb in my car! Might do that with the reverse and brake lights when they burn out eventually.....hopefully one day their LED's become price competitive and power ful enough for the front headlight!

PS: just checked their prices for tail lights and brake light, $25 each! I think its gonna be a while before LED's become powerful enough and cost effective to be on headlights!
