Buying Guide

Waterproof rating matters

Choose lights with IP67/IP68 or described submersible construction to resist immersion and frequent launch immersion

Check wiring harness length

Select a kit with a wiring harness long enough for your trailer—common options range from 25 to 29 feet to avoid splicing

Match mounting style

Pick low-profile bar lights for sleek trailers or 6" round fixtures for traditional mounting and plate illumination

Look for integrated license illumination

Kits that include a license-plate light reduce additional wiring and simplify legal compliance

Consider guide-post lights separately

Guide-post LEDs with IP67 protection help nighttime alignment when backing and are sold as dedicated post sets
