UBL 18-Inch Rubber Gasket for Light Bar — Large Black Matte Seal, UV-Stable Weather-Resistant

UBL’s 18-inch black rubber gasket is a heavy-duty visor and light-bar seal that reduces distracting windshield flashback and provides a discreet, weather-resistant mounting surface for emergency and auxiliary lights.

This gasket is built to sit between your vehicle’s light bar or visor-mounted warning light and the interior glass or dash, blocking unwanted reflections and creating a clean black border. Constructed from a high-grade, UV-stable rubber compound, the UBL 18" gasket combines long-lasting flexibility with a matte finish that blends with vehicle interiors. It’s designed for broad compatibility so technicians, fleet managers, and vehicle owners can fit many popular brands without cutting corners.

How does this gasket stop windshield flashback?

The gasket forms a continuous matte barrier that prevents light from scattering back into the cabin through the glass. By interrupting reflective surfaces and absorbing stray beams, it reduces glare that can distract drivers at night.

• Full-length 18" strip masks reflective edges where lights meet the windshield
• Matte-black rubber minimizes surface reflections
• Flexible profile conforms to curved windshields and dash surfaces

Will it fit my existing emergency light or visor mount?

UBL engineered this gasket as a universal solution to accommodate many popular light brands and housings. It accepts a variety of mounting footprints and can be trimmed for custom installs when needed.

• Compatible with Ultra Bright Lightz, Feniex, Whelen, Federal Signal, and similar models
• Flexible rubber adapts to different mounting shapes and depths
• Easily trimable for non-standard or custom light bars

Is the rubber durable enough for outdoor and daily use?

Yes — the gasket uses a high-grade, patented rubber compound formulated to resist cracking, fading, and drying. It maintains flexibility across temperature swings and stands up to sun exposure and moisture without rapid degradation.

• UV-stable material prevents yellowing and hardening over time
• Weather-resistant composition tolerates rain, heat, and cold
• Resilient construction supports repeated removal and reinstallation

How will it affect the vehicle’s interior appearance?

The matte black finish is intentionally low-profile to match most vehicle interiors and light housings. Once installed, it creates a professional, finished look that hides gaps and reduces visual clutter around lights.

• Sleek matte surface blends with dashboards and headliners
• Covers mounting seams for a cleaner installation aesthetic
• Neutral black won’t distract from interior lighting or controls
