How to replace tail lights on S-series ---- This how-to covers replacement of brake lights, rear turn signals, and reverse lights on the S-series. I did this on a 3rd gen SL2, but the instructions are probably applicable to most models and years.
You will need the following:
* A T-15 Torx screwdriver
This is a quick operation. I was able to do it in five minutes in a parking lot.
First, find out which light(s) are burned out. The easiest way is to have a helper hit the brakes/turn signal/reverse while you stand behind the car. If you can't find a helper, you can just park so your car's rear-end faces the side of a shiny car, and you should be able to see which lights are coming on in the rear view mirror.
Next, go to the auto parts store and get the proper bulbs. I used Sylvania Long Life bulbs. Don't bother with OEM bulbs, they're needlessly expensive. You can also pick up special grease to coat the bulb socket if you like (it's sold in a little packet at the counter of most auto parts stores).
Pop your trunk, and you'll see two Torx screws on the side of the tail light assembly. Use your T-15 screwdriver on these.
The tail light assembly should easily slide out at this point. You'll see four connectors: a wiring harness, reverse light, turn signal, and brake light. Disconnect the proper connector, and you'll see the burned-out bulb. Give it a yank, and it will pop right out.
Coat the new bulb's base with dielectric grease (optional), and insert the new bulb. It will go in with a satisfying snap.
Slide the tail light assembly into the body of the car, and screw the two Torx screws back in.
You probably got a 2-pack of bulbs, so go ahead and replace the same bulb on the other side of the car! It will most likely burn out soon anyway.

This is because the tail light bulb has a different element in the bulb. Just replace the bulb and that will fix the problem.

Replace the light bulb. Tail lights are usually dual filament, 2 filaments in one bulb.
take it to chevy
Turn you high beams on and check your tail light. If its brighter, you have a head light bulb as a tail light bulb. 97-02 are the only ones that should do this. Find a tail light bulb and replace.(I couldn't believe it either).
