Dorman Clearance Light Assembly

Dorman Clearance Light Assemblies: Direct-Fit Replacements Built to Last

When a truck's roof marker or cab clearance light goes dark — whether from cracking, hazing, or moisture infiltration — it's more than a cosmetic problem. Clearance light assemblies are federally mandated visibility components on larger trucks and vans, and a failed unit can mean a DOT violation or a failed state inspection. That's where Dorman steps in with a straightforward solution engineered specifically for working vehicles.

What Makes Dorman's Clearance Light Assemblies Stand Out

Dorman has been a fixture in the automotive aftermarket since 1918, building a catalog that now spans tens of thousands of replacement parts for light-, medium-, and heavy-duty vehicles. Their clearance light assemblies fall squarely in their wheelhouse: simple, hard-to-find exterior lighting components that OEM dealers often overcharge for or discontinue entirely.

Each Dorman clearance light assembly is engineered as a direct replacement, precisely matching the fit and appearance of the original factory unit. This means no cutting, splicing, or bracket fabrication — just a clean swap that restores your truck's lighting to proper working order. Dorman subjects these assemblies to vehicle try-on testing to confirm accurate fitment and ease of installation before they ever reach a shelf.

UV-Resistant Construction for the Long Haul

Dorman manufactures these roof marker and cab clearance light assemblies from UV-resistant polymers, a deliberate material choice that addresses one of the most common failure modes on exterior lighting — sun-induced hazing and brittleness. On a working truck that spends years exposed to the elements, lens durability matters as much as initial fitment.

Coverage spans a broad range of popular commercial and fleet vehicles. Dorman's clearance light lineup includes applications for Ford E-Series and F-Series Super Duty models, as well as Dodge and Ram 2500, 3500, 4500, and 5500 trucks across multiple model years — making these assemblies a reliable go-to for fleet managers and individual truck owners alike.
