Automotive Vehicle Top Clearance Light Assemblies

A top clearance light assembly mounts on the roof or cab to improve vehicle visibility and indicate width and height to other drivers; it's often required for vehicles exceeding certain width or commercial vehicle classifications and improves nighttime and adverse-weather visibility

Match the assembly to your vehicle's mounting style, voltage (typically 12V), and required SAE/ DOT certifications; verify dimensions, lens color (amber or red), wiring connector type, and whether you need sealed or replaceable LED modules

LED lights consume less power, have longer expected life, and respond faster, while incandescent lights are usually cheaper upfront but run hotter and require more frequent bulb replacement; check lumen output and IP rating rather than type alone

Many jurisdictions require clearance lights on commercial or wide vehicles and specify color and placement (amber forward and red rear in some regions); consult local vehicle codes for exact rules to ensure compliance

Prices vary by brand, build quality, and features: budget options are commonly under $50, mid-range LED assemblies often range from $50–$150, and heavy-duty or certified commercial units can cost more

Look for IP67 or similar ingress protection ratings, corrosion-resistant housing (ABS or die-cast aluminum), impact-resistant lenses, and silicone or rubber seals to prevent water intrusion and extend service life

Installation is usually straightforward with basic wiring skills—mounting screws and pigtail or plug connectors are common; many LED assemblies are sealed units requiring whole-unit replacement, while some designs allow lens or bulb replacement
