How to Replace a Corner Light (Step by Step)

Stand in front of your car and look at the front corners. The corner light is the small amber lens near the edge of the bumper or fender, usually tucked between the headlight and the outer fascia. On older vehicles it was a separate housing sitting in the fender corner. On vehicles from the 1990s and 2000s it's often a small lens integrated into the front fascia just outside the headlight. Some vehicles have it below the headlight, others have it at the same level. Walk around and look at both sides so you're sure which one needs replacing.

Most corner lights come out from the front. Look along the edge of the housing for one or two Phillips screws. They're sometimes hidden under a rubber seal or in a recessed slot. Remove the screws and the housing should pull straight forward and out. On vehicles where no screws are visible, the housing is held in by a spring clip or a tab. Try sliding the housing toward the front of the car, then pulling it out. If it still won't budge, open the hood and look from behind the headlight assembly. On some vehicles you can reach the socket and remove the bulb entirely from behind the headlight without pulling the housing out at all.

With the housing in hand or accessible from behind, grip the socket and turn it counterclockwise about a quarter turn, then pull it straight out. For wedge-base bulbs like a 194 or 168, the bulb pulls straight out of the socket with light, even pressure. For bayonet-style bulbs like a 1157 or 3157, push the bulb in slightly and rotate it counterclockwise to unlock it, then pull it out. Once the socket is out, look at the contacts inside. Green corrosion or black discoloration are signs the socket is corroding. Sand the contacts lightly with fine sandpaper before installing the new bulb. A corroded socket is why bulbs keep burning out every few months.

Push the new bulb into the socket. Wedge-base bulbs go straight in until snug. Bayonet-style bulbs push in and then rotate clockwise until they lock. Don't force it. If it won't seat smoothly, check that you have the right bulb. The bases are not interchangeable and a wrong-base bulb won't fit regardless of how hard you push. If you're using an LED replacement, these are polarity-sensitive. If it doesn't light up during your test, pull it out, flip it 180 degrees, and try again. It'll work in one direction and not the other.

Plug the socket back into the housing, then test before you put everything back. Turn on your parking lights or headlights and confirm the corner light comes on. If your vehicle uses the corner light as part of the turn signal circuit, activate the turn signal and confirm it blinks. Getting in the habit of testing before reassembling saves you from a second disassembly when you realize you put it back together with a bad bulb or a loose socket.

Line up the housing with the mounting slots in the fender or bumper fascia. Push it straight in until you feel it seat. The mounting tabs have to engage the slots before the housing will sit flush. Once it's in place, reinstall any screws you removed and tighten them down. Don't overtighten screws going into plastic. Snug is enough. Give the housing a light push with your palm to confirm it's solid and flush with the surrounding body panel. A gap around the housing lets water in, which corrodes the socket and kills the next bulb early too.
