Truck-Lite Trailer Light

Truck-Lite Trailer Lights: Safety Lighting Built on Seven Decades of Innovation

When it comes to trailer lighting, few names carry the weight that Truck-Lite does. Trailer lights are among the most safety-critical components on any towed vehicle — and Truck-Lite's entire legacy was built on solving exactly this problem. Truck-Lite founder George Baldwin set the company in motion in 1955 by designing the first sealed marker light to address the notoriously short service life of trailer lights of that era, using his own kitchen sink as a quality-control station. That single innovation sparked a revolution in commercial vehicle safety lighting that continues today.

A History of Industry Firsts in Trailer Lighting

Truck-Lite's credentials in the trailer lighting space are rooted in a long list of genuine industry firsts. The company introduced the first sealed stop/turn/tail light for commercial vehicles, and went on to pioneer the first LED stop/turn/tail (S/T/T) lamps in the commercial transportation segment — innovations that fundamentally changed what fleets expected from their trailer lighting. Today, backed by Clarience Technologies, Truck-Lite offers more than 5,000 certified and tested products, all backed by industry-leading lifetime warranties.

Trailer Light Product Lines That Define the Category

Truck-Lite's trailer light catalog spans a wide range of applications and technologies, making it straightforward to find the right fit for any trailer configuration:

• 34 Series LED Trailer Lights — Designed for U.S.-manufactured specialty trailers, the 34 Series offers a dedicated LED option built for consistent output, durability, and easy retrofits. Three-wire versions include an auxiliary stop function with a clear high-to-low output ratio to help following drivers identify braking activity more easily.
• Super 60™ & Super 66® Series — The Super 60™ is a 6.5" sealed grommet-mount stop/turn/tail lamp available in kit form with lamp, grommet, and 3-pole pigtail. The Super 66® takes it further as the world's first SingLEDiode® stop/turn/tail lamp, representing a significant leap in LED trailer light design.
• Model 40® Series — A 4" sealed stop/turn/tail grommet-mount light engineered for rough-road durability, with a heavy-duty shock-mounted bulb for demanding trailer applications.
• Model 80® Series — A high-performance flush-mount option with a black plastic housing, ideal for trailers requiring a low-profile rear lighting solution.
• LED Marker & Clearance Lights — From the compact Model 15® sealed amber marker (designed to fit narrow header rails) to multi-diode rectangular clearance lights with encapsulated electronics that prevent moisture and corrosion damage, Truck-Lite's marker and clearance lineup covers virtually every trailer mounting scenario.
• Signal-Stat Personal Trailer Kits — Complete LED trailer light kits with left-hand and right-hand S/T/T lamps for personal-use trailers, making compliance and installation straightforward for owner-operators.

Why Truck-Lite Stands Apart for Trailer Lighting

What makes Truck-Lite trailer lights a trusted choice for fleets, OEMs, and owner-operators alike is the combination of proven engineering, LED technology leadership, and a commitment to compliance. Many of the brand's LED designs feature encapsulated electronics to eliminate pin corrosion — a common failure point on trailers exposed to road wash and weather. Certain clearance lights are even hard-wired to remove corrosion-prone connector pins entirely. Coupled with industry-leading lifetime warranties and availability through more than 20,000 distribution locations worldwide, Truck-Lite trailer lights represent a long-term investment in uptime and safety.
