Buying Guide

Match light size to your trailer

Measure mounting holes and gasket openings; 4-inch and 6-inch fixtures are common and must align with your existing cutouts for easy swap-in

Prefer waterproof and corrosion-resistant

Look for IP67/IP68 or waterproof housings and stainless or sealed connections to resist saltwater and trailer exposure

Check SAE/DOT compliance

Choose lights marked SAE or DOT compliant for legal taillight, stop, and turn functionality on public roads

Consider LED count and visibility

Higher LED counts and clear lenses often improve brightness and viewing angle for safer towing at night

Assess wiring and plug options

Kits with grommets, pigtails, or standard plugs simplify installation and reduce the need for splicing

Balance cost and long-term value

Budget options under $50 can offer good durability, while higher-end units provide extra sealing and longer lifespans
