Be sure to pick the correct size and bulb type to install the marker lamp in order not to overheat the lamp, cause harm to the socket or create a wiring issue. It only applies to products built for national consumers since export companies replace the bulb, socket and wiring for the front side marker with a white reflector. Place the base of the bulb where marker bulb socket 2 is, then push the bulb straight into the socket until it is properly seated. Then, put the socket and bulb onto the keyed entry on marker lamp housing 1 on the inside of the outboard-facing front fascia 4 and insert them as far as possible so the socket is secure. Turn the socket to your left a little more than a quarter turn (30 degrees) to secure it in place with the bulb connector pointed below. After you have reconnected wire harness connector 3 to its socket in the bulb, reinstall the front fender wheel house liner. When complete, link the negative cable to the battery once again.
