Paint Protection Film for Headlights and How to Choose It

A bonnet and a headlight can meet the same piece of motorway grit, but protecting them calls for different checks. A bonnet needs a sound finish. A headlight also needs to send the right light onto the road. Any film placed over its outer lens becomes part of that optical path.
Paint protection film for headlights is intended to add a replaceable barrier against light abrasion and some road-debris damage. It can be useful on a suitable lamp, provided the film is approved for that surface, the lens is in good condition and the finished installation meets the requirements where the vehicle is used. It is not a repair for a cracked lens or a way to make a failing headlight perform like new.
For an owner, the decision starts with the actual lamp. For an installer or distributor, it starts with a documented product specification. This guide explains the practical differences between headlight film, ordinary body PPF and cosmetic tint, then sets out the questions to ask before fitting or ordering film.
