Your Gmc S15 headlight assembly is an important component of the automobile. When you are driving at nighttime and through inclement climatic situations, you can use your headlamp to provide illumination on the road or through rain streaks. It is mounted on the frame of your vehicle using a housing or socket that secures it in its seat. It is connected to a switch on your vehicle's dashboard or steering wheel and to a relay that in turn taps the main power source of the vehicle.

There are a pair of categories for the Gmc S15 headlight assembly according to construction, the sealed and the composite. You will have to replace your OE sealed lamp as one component. A composite headlamp may be replaced in a 'per part' , which is usually an aftermarket lamp. Sealed or composite, your headlamp has distinct engineering and performance specs that adhere to predetermined standards in a state and country.

Over time, the Gmc S15 headlight assembly will wear or get busted. You may opt to replace it with an OE-style or a composite aftermarket. Here at Parts Train, we have both types from world-class GT Styling, Wade Auto, Hella, or Replacement brands.
