Headlight bulb — replacement
Warning: Halogen gas-filled bulbs are under pressure and can shatter if the surface is scratched or the bulb is dropped. Wear eye protection and handle the bulb carefully, grasping it only by the bulb holder. Do not touch the surface of the bulb with your fingers because the oil from your skin could cause it to overheat and fail prematurely. If you do touch the bulb surface, clean it with rubbing alcohol.
1. If you’re replacing a right-side bulb on a truck model, remove the air filter housing (see Fuel and exhaust systems). If you’re replacing a left-side bulb on a truck model and the vehicle is equipped with an auxiliary battery, remove the battery.
2. Remove the dust boot and disconnect the headlight bulb electrical connector. Rotate the bulb counterclockwise and remove it from the housing (see illustrations).
