Buying Guide

Match fitment to vehicle

Confirm year, make and model compatibility (for example Silverado 2003–2006 fitments) or trailer mounting size (6-inch oval) to ensure proper fit and wiring alignment

Choose LED vs incandescent/halogen

LED kits provide longer life and lower current draw for trailers, while OE-style incandescent or halogen housings may be preferred for factory-correct replacements on older GM trucks and SUVs

Check wiring and harness requirements

Look for units that include bulb harnesses or clear wiring specs to avoid extra parts; trailer kits often list SAE/DOT compliance for suitable wiring integration

Assess weatherproofing and durability

Select assemblies described as weatherproof or with sealed LEDs for exposure-prone use on trailers and trucks to reduce corrosion and moisture intrusion

Consider regulatory and safety markings

Prefer lights with SAE/DOT certification or equivalent markings for road-legal compliance and predictable photometric performance
