I got pulled over Monday night with a tail light out. :grump: Luckily, I've gone through this process...I mean, I've read about it....and it was quick and painless. I replaced the bulb, and now I have a stop and turn signal, but the running light still doesn't work. It's a 2002 Chevy S-10. Any ideas? I switched the bulbs from the left to right and the right one worked with both bulbs and the left one didn't with either, so I know it isn't the bulb.
