A headlight filler<\/a> is a trim piece that closes the gap between your vehicle’s headlight assembly<\/a> and the surrounding bumper, grille, or fender so that the front end looks finished and stays protected. It’s mostly cosmetic, but it also helps keep debris and moisture out of the gaps around the headlight housing. On many vehicles, the filler snaps into place with small retaining clips<\/a> and lines up flush with the headlight edge.<\/p>\n\n\n\n
