407560 LED Low-Profile Taillight Kit
Product includes: Wiring; stainless-steel hardware; license-plate bracket; driver-side taillight with license-plate illuminator; passenger-side taillight.
Product lacks: Side-clearance lights; center taillight (both required for trailers wider than 80 inches).
Product highlights: Totally watertight with tinned wire for better corrosion protection. Taillight connector plugs are greased for added protection. The electronics aren’t potted but they are doubly protected by a waterproof housing and a tough-to-crack inner light pod.
Best application: Saltwater or freshwater marine trailering application.
Downside: Why not supply silicone-sealed butt connectors — or perhaps heat-shrink connectors?
