Universal Butyl Headlamp Sealant - Single (DIODD4048)

Properly reseal any headlamp or tail lamp and protect against moisture ingress with Diode Dynamics Butyl Headlamp Sealant! This automotive-grade butyl rope is designed specifically for lighting applications, featuring a firmer composition than standard windshield glue to prevent a sticky mess during installation. With a 7mm diameter that fits perfectly into most headlamp channels, this sealant ensures a factory-quality watertight barrier. Each roll provides 20 feet of material, which is more than enough to completely reseal two large headlamps after custom LED modifications.

Notes

• While this sealant creates a watertight barrier between the lens and housing, all lamps have built-in ventilation that may still allow humidity to enter.
• For enhanced protection against condensation, consider adding breather patches to improve internal airflow.
• Warm the sealant rope before placing it in the channel for the best results and a more secure bond.
