Reach up behind the front bumper area from under the vehicle to access the lamp housing. 3. Remove the electrical connector from the bulb by lifting the two plastic clips. Halogen Bulbs { WARNING Halogen bulbs have pressurized gas inside and can burst if you drop or scratch the bulb. You or others could be injured.
