How to Replace the Tail Light Bulb on a 1998 Silverado
The taillight assembly on a 1998 Chevy Silverado houses the brake/taillight combination bulb, the reverse bulb and the turn-signal bulb. The brake/taillight combination bulb takes one type of bulb or another depending on when and where the 1998 Silverado was manufactured. Most 1998 Silverados use the 3057 automotive replacement bulb, but some use an 1157 replacement bulb. Getting to the bulbs requires a single procedure regardless of which bulb your 1998 Silverado uses, but there is a slight difference for extracting the different bulbs from their respective sockets.
Instructions
- 1
Ensure the headlight switch inside the passenger cab is in the off position.
2Open the 1998 Chevy Silverados tailgate.
3Locate the two retaining screws on the taillight assembly (the screws were revealed after you lowered the tailgate) that has the faulty taillight bulb. Remove the two screws with the Phillips screwdriver.
4Turn the assembly around and rest it on the bumper with the wire harness still connected to the underside of the headlight assembly.
5Grasp the taillight socket and twist it counterclockwise 1/3 turn to remove the bulb and socket from the taillight assembly.
6Pull the 3057 replacement bulb straight out of the socket and push the new replacement bulb into the socket. For the 1157 bulb, remove the old one by pushing down on the bulb slightly while twisting the bulb 1/4 turn counterclockwise, then pulling the bulb from the socket. Align the dual notches on the base of the replacement bulb to the grooves inside the socket. Push the bulb slightly downward while twisting it clockwise to lock the bulb in the socket.
7Align the notches on the external section of the socket with the matching grooves in back of the taillight assembly.
8Reinstall the taillight assembly and replace the retaining screws. Close the tailgate.
