Betts Combination Light Assembly

About Betts HD

When it comes to keeping commercial trucks, trailers, and heavy-duty vehicles visible and compliant on the road, Betts HD has earned a trusted reputation among fleet operators, owner-operators, and equipment professionals. Headquartered in the United States, Betts HD has long specialized in manufacturing robust lighting and visibility products designed to meet the demanding requirements of the trucking and commercial transportation industries.

Betts HD products are engineered to perform in the punishing conditions that working vehicles face every day — from highway miles in all weather to job site environments where durability is non-negotiable. Their catalog spans a focused range of exterior lighting solutions that help vehicles meet federal and state visibility regulations while standing up to vibration, moisture, and road debris.

Commercial Vehicle Lighting You Can Count On

At the core of the Betts HD lineup are identification lights, the cluster lights typically mounted at the top of cab and trailer faces that signal a vehicle's width and presence to other drivers. These lights are a federally mandated safety feature for vehicles over 80 inches wide, and Betts delivers solutions built to last in real-world operating conditions.

Betts HD also offers a strong selection of LED clearance and marker lights, which represent the modern standard for commercial vehicle lighting. LED technology brings significant advantages to fleet owners: longer service life, lower power draw, and superior brightness compared to incandescent alternatives — all of which translate into reduced maintenance costs and improved roadside visibility.

For vehicles requiring side visibility compliance, Betts HD's side marker lights provide reliable, regulation-ready solutions. These lights are positioned along the sides of trailers and longer vehicles to make them visible from angles that front and rear lights cannot cover — a critical safety function on multi-lane highways and at intersections.

Beyond individual marker and identification units, Betts HD manufactures combination light assemblies that integrate multiple lighting functions — such as stop, tail, turn, and marker — into a single, streamlined unit. These assemblies simplify installation and reduce wiring complexity, making them a practical choice for fleet maintenance teams and body builders alike.

Rounding out their lighting portfolio, Betts HD also produces vehicle-mounted work lights that deliver focused illumination for utility, service, and specialty vehicles that need to operate effectively after dark or in low-light environments.
