You cannot block the headlights or taillights completely, which makes protecting them a bit of a trick for aftermarket suppliers. This is not to say that options are limited and there are plenty of means to provide protection to the headlights and tail lights effectively. Some of the most common methods include a protective barrier placed over or in front of the lights while others are a protective coating that sits on top of the lens.
Weathertech’s Urethane Film: Weathertech is a brand that is known for providing excellent levels of protection to vehicles. Their Lampguard urethane film is an excellent choice as a first level of protection for headlight lenses. This is a thick transparent film that sits on top of the lens itself. The thick layer of protection is designed to take rock strikes that could easily shatter the lens.
Light Guards: Light guards are generally used for the tail lights of the vehicle. These are small steel cages that fit over the housing. These are meant to keep large materials like sticks and rocks from ever making contact with the lens itself.
Brush Guards with Headlight Covers: Grille guards fit to the frame of the truck and come up to protect the grille, and the brush guards extend outward to protect the headlights. These offer a similar level of protection as light guards do for the tail lights. The concept is to prevent the lens from ever taking an impact at all.
Bumpers with Brush Guards: Grille guards have the tendency to flex under impact and their ability to protect the lenses can be hindered. Aftermarket bumpers with brush guards built in have a much higher level of integrity and will not flex on impact. These will work the best to keep the headlight lenses safe from impact.
