Diode Dynamics Butyl Headlamp Sealant is an automotive-grade rope designed to reseal headlamps and tail lamps and protect against moisture ingress. The 7mm-diameter sealant is easy to work with and avoids a sticky mess, provided in 20 feet of material — enough to reseal two large headlamps. Its firmer composition is tailored for headlamp channels and allows a neat, reliable reseal for lamp housings.
