Light Bulb Size Guide
Not that I know of
I bought some Red LEDs off of ebay. When i finally got all the stock bulbs out of the interior (and trunk), i put in the red leds i got, but NONE of them worked!
Then when i went to put the original bulbs in, THEY DIDNT WORK EITHER!?!?!?
Now i only have 1 standard yellow factory bulb in the OnStar mirror and a red LED in the dome light(which works, but then again i got it from a different vendor). Im wondering if it may have to do with the fact that i bought 10 of them for...$5 from China

What Mike said. You can touch them all you want, the do however have to go in the right way 90% of the time.
You may have blown a fuse also if the original ones are working, but that doesn't happen often with LEDs

Well, the reason I ask is because of these, that supposedly replace the model of bulbs that are in our headlights. A bit on the expensive side for lightbulbs, but I was curious anyway.
