Easy to work with. Properly reseal any headlamp or tail lamp and protect against moisture ingress with Diode Dynamics Butyl Headlight Sealant! This new and improved sealant rope was designed specifically for headlamps, with a firmer composition than auto-store windshield glue. This makes it easy to work with, without causing a sticky mess. Each roll comes with 20 feet of butyl, enough to reseal two large headlamps.


Protection from moisture. Use it to reseal any headlamp after installing Diode Dynamics LED products! Warm it up a bit, place it into the headlight channel, and clamp together while heating, making sure the lens is fastened to the housing. With a little practice, you'll have a factory-quality seal, with quality butyl that will protect against moisture ingress for years to come.
