How do you replace a marker light on the right front for a 1998 Isuzu trooper?

To replace the right front marker light on a 1998 Isuzu Trooper, first, ensure the vehicle is turned off and the keys are removed. Open the hood and locate the marker light assembly; then, remove the screws or clips holding the assembly in place. Carefully pull the assembly out, disconnect the wiring harness, and replace the old bulb with a new one. Reconnect the wiring, secure the assembly back in place, and test the new light to ensure it works.
