UBL 18" Large Black Rubber Gasket for Light Bar — Matte UV-Resistant Seal, Reduces Windscreen Flashback

UBL's 18-inch large black rubber gasket is a heavy-duty visor seal that reduces windshield flashback and provides a clean, low-profile mount for emergency and auxiliary light bars.

This gasket is engineered to sit between a vehicle's visor area and mounted lights to limit distracting reflections, protect the windshield sealing surface, and give a professional, matte-black finish. Built from a patented high-grade rubber compound, the gasket resists UV, weather, and daily wear so it performs reliably across seasons and vehicle types.

How does the gasket reduce windshield flashback and driver distraction?

The gasket creates a non-reflective barrier that blocks light from bouncing off the glass and back into the driver’s line of sight. Its matte surface and contoured profile absorb stray beams, helping maintain clear sightlines during night or low-light operations.

• Matte black finish minimizes reflective surfaces
• Contoured inner edge fits light housings to contain beam spill
• Seals gaps between light bar and windshield to stop light leakage
• Works with a wide range of light shapes and beam patterns

Will this gasket fit my light brand or model?

UBL designed the 18-inch gasket for broad compatibility with many popular light manufacturers. It’s a flexible solution that accommodates visor, dash, and surface-mount lights without needing brand-specific adapters.

• Compatible with Ultra Bright Lightz, Feniex, Whelen, Federal Signal and similar units
• Flexible rubber conforms to several light housing profiles
• Works for both permanent and semi-permanent installations
• 18-inch length covers most standard visor-mounted bar widths

How durable is the rubber—will it hold up outdoors and over time?

The gasket is molded from a patented high-grade rubber formulated for prolonged exposure to sunlight, temperature swings, and road conditions. It resists cracking, drying, and fading so the seal and appearance remain consistent through regular use.

• UV-resistant material prevents sun-related degradation
• Weatherproof compound tolerates heat, cold, and moisture
• High-flex rubber returns to shape after compression
• Matte surface resists staining and maintains low visibility

How easy is installation and maintenance?

Installation is straightforward: position the gasket between the light and windshield or dash surface, align holes or edges, and secure your light per the manufacturer’s instructions. The gasket requires minimal upkeep—clean with mild soap and water as needed.

• Simple fit-and-seal design for quick installs
• No special tools required beyond standard mounting hardware
• Clean with non-abrasive, mild detergents only
• Can be trimmed carefully for custom fits
