Over time, your 1987-1993 Mustang headlight seals can become deteriorated which allows moisture in the headlight lens. This can cause your headlights to become fogged, discolored, or make your bulbs burn out. We offer these direct replacement headlight seals, often called headlight weatherstrip, to keep your Mustang looking great. This rubber trim easily installs onto your headlights with the preinstalled clips. Only fits 3 piece headlights. Pick up a set today to replace your old seals or add a set to your new headlights for a quick and easy installation.
