Truck-Lite 27009-1 5"x7" Rectangular Halogen Headlight | Clear Glass Lens, Die-Cast Aluminum, 12V Display Pack

Restore crystal-clear road visibility and heavy-duty structural durability to your forward lighting system with the Truck-Lite 27009-1 5"x7" Rectangular Halogen Headlight. Shipped in an individual retail display pack, this premium 12V high/low dual-beam headlamp is engineered as a high-performance upgrade or direct replacement for standard 7x6" (200mm) rectangular sealed-beam lamps. It is the premier choice for commercial semi-trucks, delivery box vans, fleet utility vehicles, and classic rigs requiring top-tier down-road lighting performance.

Advanced Optics & Elite Road Performance

Say goodbye to weak, dim beam patterns. The Truck-Lite 27009-1 utilizes an advanced multi-surface reflector design paired with a crystal-clear, non-heated glass lens that optimizes light dispersion and prevents pattern distortion. This headlamp dramatically outperforms traditional factory lighting, exceeding DOT minimum beam requirements by an average of 300% on low beam and 225% on high beam. Equipped with a mechanical aim profile, it targets precise light direction exactly where you need it on the highway for safer night driving conditions.

Built for Fleet Longevity & Easy Maintenance

Engineered to withstand the demanding conditions of long-haul commercial transport, this headlight features a rugged die-cast aluminum alloy rear housing that rapidly dissipates heat away from the internal filament, preventing overheating and premature component failure. Unlike glued, one-piece sealed beams, the 27009-1 features a highly cost-effective, bulb-replaceable design. It utilizes a standard 9003/HB2 halogen bulb with an industry-standard H4 connector, allowing maintenance crews to swap out an expired bulb in minutes without discarding the entire headlight assembly—slashing long-term operational costs.
