Your Mercury Mariner headlight assembly is an integral part in your automobile. When hitting the road at night or under inclement climatic situations, you should use it to light up the road or through rain streaks. This part is mounted on the frame of your own car through a housing or socket that actually gets it in its seat. It is attached to its switch on the dash or steering wheel and to a relay , which in turn taps the main power source of the automobile.

The Mercury Mariner headlight assembly is categorized as a sealed type of lamp. A sealed lamp is usually an OE part and acts as one unit; it fails and is replaced as a single part. A composite headlamp may be replaced in a 'per part' , which is commonly an aftermarket lamp. In performance, both lamp styles can function effectively through extreme conditions.

Even how tough the Mercury Mariner headlight assembly is, its daily operations and the its location can cost it its service life. When it's donned or irregular, you have to look for the component that fits the needs of your car to preserve its original performance. Here at Parts Train, we cater both types from world-class GT Styling, Wade Auto, Hella, or Replacement brands.
