Buying Guide

Waterproof rating matters

Choose lights with IP67/IP68 or described submersible construction to resist immersion and road spray

Check included wiring harness

Prefer kits that include a wiring harness and sufficient length (25–29 ft options) to avoid buying extra cabling

Low-profile vs bar styles

Low-profile lights mount discreetly and resist snags, while LED bar kits offer brighter, continuous illumination for visibility

Match 12V electrical systems

Confirm lights are 12V LED to be compatible with standard trailer and vehicle electrical systems

Guide-post options for docking

Consider post or guide lights (IP67-rated) when you need vertical markers to assist loading and docking at night
