Optronics Clearance Light Assembly

Optronics Clearance Light Assemblies: Built for Visibility, Built to Last

When it comes to marking the widest point of a trailer or commercial vehicle, few names carry more authority than Optronics. Founded in 1972, Optronics International has grown into one of the most trusted names in vehicular safety lighting, and their clearance light assemblies represent some of the finest examples of that legacy.

Clearance lights aren't merely a regulatory checkbox — they are a critical safety system that tells other drivers exactly how wide and how tall your vehicle is in low-visibility conditions. Optronics takes that responsibility seriously, engineering assemblies that meet or exceed FMVSS 108 compliance standards. As noted by Vehicle Service Pros, Optronics conducts photometric and mechanical testing at points of manufacture and distribution to ensure quality consistency and FMVSS 108 compliance across their entire safety lighting lineup.

What Sets Optronics Clearance Light Assemblies Apart

Optronics offers clearance light assemblies in both LED and incandescent configurations, serving everything from light-duty cargo trailers to heavy commercial vehicles. Their fender-mount assemblies are pre-wired for fast, straightforward installation — typically featuring one amber front clearance light and one red rear clearance light housed in a single bracket, ready to mount on top or on the side of a trailer fender.

Key design features found across the Optronics clearance light assembly lineup include:

• Sonic welding: Lenses and housings are sonically sealed, creating a waterproof barrier that protects internal components from road spray, rain, and wash-down environments.
• PC-rated dual-function capability: Many assemblies are PC-rated, meaning a single light can function as both a clearance light and a side marker light when mounted at a 45-degree angle — reducing the total number of components needed.
• LED efficiency: Optronics LED assemblies use a fraction of the electrical current of conventional incandescent bulbs, light up faster, and deliver significantly longer service life — important for fleets focused on minimizing downtime.
• Lifetime LED Warranty: Select Optronics LED marker and clearance products are backed by a lifetime LED warranty, reflecting the company's confidence in its solid-state construction.
• Reversible and smoke-lens options: The lineup includes specialty configurations such as reversible fender assemblies and smoke-lens versions, giving builders and owner-operators styling flexibility without sacrificing compliance.

A Lineup Designed for the Real World

Optronics clearance light assemblies are engineered for trailers over 80 inches wide — the threshold at which federal regulations require clearance marking. Whether you're maintaining a single utility trailer, outfitting a fleet of flatbeds, or building a new RV, Optronics has an assembly sized and rated for the job. Their catalog spans compact 3/4-inch sealed marker/clearance lights all the way up to full LED fender light assemblies, ensuring compatibility across a wide range of trailer types and mounting configurations.
