Key Features:

This butyl sealant creates a watertight, airtight seal when reassembling headlamp housings after modifications, bulb upgrades, or lens replacements. The 7mm diameter is engineered to match factory headlamp channel dimensions, ensuring proper fitment without gaps or excess material. Unlike adhesive-based sealants, butyl remains flexible and can be removed cleanly for future maintenance.
