✨ Why You’ll Love This Sealant

Engineered for headlight builds—not bathroom caulking. This extra-thick, automotive-grade rubber silicone sealant is the go-to choice for pros and DIY modders who need a clean, weatherproof seal on cut-open housings. Thicker than typical store-bought silicone, it’s purpose-built to handle the vibration, heat, and sealing demands of custom lighting.

  • ✅ Headlight-Specific Formula – Not your average silicone—this is thicker, tackier, and built to bond

  • 💧 Superior Waterproof Protection – Seals out moisture and keeps lenses fog-free

  • 🔥 High-Temp, High-Flex – Withstands extreme temperatures and constant road vibration

  • 🧰 Perfect for Cut-Open Housings – Ideal for retrofits and custom assemblies

  • ⚙️ Universal Fit – Compatible with most vehicle headlights, OEM or aftermarket

🛡️ If you’re cutting open headlights, don’t settle for over-the-counter silicone. Use what the pros use.

  • Use Case: Designed for cut-open headlight housings (not baked-open)

⚠️ Cut-Open vs. Baked-Open Housings

This sealant is specifically designed for housings that have been cut open (e.g. using a Dremel or similar tool).
For baked-open housings, we recommend using our Butyl Resealing Strip instead.

✅ Choose the right sealant based on how your headlight was opened to ensure proper bonding and seal integrity.

🛠 Installation

Apply a thin, even bead around the headlight channel after trimming or modifying your housing. Smooth with a gloved finger or plastic tool, and allow proper curing time for maximum protection.

Tools Needed:

  • Precision cutting tool (if opening headlights)

  • Plastic spreader or gloved hand for smoothing

  • Basic toolset for disassembly/reassembly
