How to Replace the Turn Signal Light on a 2001 Isuzu Trooper

The Isuzu Trooper hit U.S showrooms in the early 1980s and it continuously evolved into a more comfortable and refined SUV through each generational change. The Trooper reached its pinnacle in its final generation, which lasted from 1998 through 2002. Part of the refinement process of this SUV was the streamlining and smoothing of the exterior lights. Replacing the turn signal lights on the 2001 Trooper requires removing the light assemblies to access the bulbs they contain.

Instructions

Open the Troopers hood and trace the arm on the top of the turn signal lens assembly until you reach its mounting screw.

Remove the lens assemblys mounting screw with a ratchet and socket, and pull the turn signal assembly away from the front of the Isuzu just enough to access the sockets on the rear of it.

Twist the upper socket counterclockwise to unlock it. Pull the socket from the turn signal lens assembly, exposing the turn signal light.

Press the turn signal light downward and rotate it counterclockwise to unlock it. Pull the light from the socket. Make a note of how the staggered protrusions on the base of the bulb are positioned, as you must install the new light in the same position.

Hold a new style 1157A bulb with a clean, lint-free cloth and position its metal protrusions in the same way the old bulb was positioned. Press the bulb into the socket and keep downward pressure as you turn it clockwise to lock it into place. If the bulb does not turn, it means you have it in the wrong position. In this case, remove the bulb, rotate it 180 degrees and repeat this step.

Insert the socket and new bulb into the turn signal lens assembly and twist the socket clockwise to lock it into place. Guide the turn signal lens assembly into its bed in the front of the SUV until the screw hole in the assemblys arm aligns with the screw hole under the Troopers hood.

Thread the turn signal lens assembly screw by hand, then tighten it with a ratchet and socket.

Close the Troopers hood.

Follow steps 4 and 5 in the Front Turn Signal Light section to remove the old light and install a new style 1156A bulb.

Insert the bulb and socket back into the combination light assembly and twist the socket clockwise to lock it into place.
