Attwood Marine Submersible Trailer Light Kit, Wiring Harness, License Plate Bracket

Overview

The Attwood Marine Submersible Trailer Light Kit is a trailer lighting kit range for boat trailers that need stop, tail, and turn lighting for road use and repeated ramp exposure. The range includes configurations for trailers up to 80 inches wide and over 80 inches wide, with incandescent and LED light type options depending on the trailer setup.

Each kit uses submersible multi-function trailer lights and is built around common trailer lighting needs: rear visibility, turn signaling, brake indication, and a license plate bracket. The kits conform to applicable U.S. FMVSS and Canadian CMVSS safety standards, which matters when replacing worn lights before towing to the ramp or setting up a trailer for regular highway use.

Key features

• Submersible trailer light kit range for boat trailers that are exposed to ramp launches, washdowns, and wet road conditions.
• Available for trailer width fitment up to 80 inches or over 80 inches, including low-profile options for wider trailers.
• Choice of incandescent or LED light type, so the kit can match the trailer lighting style already in use.
• Multi-function stop, tail, and turn lighting supports the core rear lighting functions needed for towing.
• Conforms to applicable U.S. FMVSS and Canadian CMVSS safety standards for trailer lighting.
• Includes the main parts needed for a trailer light replacement: two lights, wiring harness, license plate bracket, and mounting hardware.

Variants

This product is offered in four configurations that vary by trailer width fitment and light type. The wider-trailer versions use a low-profile format, while the up to 80 inches versions are the standard width-fitment kits in this range.

The package format remains consistent across the range, with a pair of trailer lights, wiring harness, license plate bracket, and mounting hardware included. The practical difference is whether the trailer falls under or over the 80 inch width category, and whether incandescent or LED lighting is preferred for the trailer.

• 14060-7: trailer width fitment up to 80 inches, incandescent light type. This configuration suits boat trailers that fall within the up to 80 inches lighting category and need an incandescent replacement kit.
• 14063-7: trailer width fitment over 80 inches, low-profile, incandescent light type. This configuration fits the over 80 inches trailer category while keeping the lamp housing profile lower at the rear of the trailer.
• 14064-7: trailer width fitment over 80 inches, low-profile, LED light type. This configuration matches the wider trailer category and uses LED lighting in the low-profile housing format.
• 14065-7: trailer width fitment up to 80 inches, LED light type. This configuration is the LED option for trailers in the up to 80 inches width category.

Installation and fit

Before ordering, confirm the trailer width category first, since the lighting requirements change at the 80 inch mark. A trailer over 80 inches wide needs the over 80 inches kit version, while smaller trailers use the up to 80 inches version.

The included wiring harness and hardware make this a practical replacement kit for worn, cracked, corroded, or intermittent trailer lights. During installation, routing the harness away from pinch points, sharp frame edges, and moving suspension parts helps reduce wiring failures after repeated launches and retrievals.

Use cases on board and at the ramp

This kit is a good match for boat owners who tow to local ramps, marinas, storage yards, and service shops, where trailer lights may be exposed to water, road spray, vibration, and salt residue. It is especially useful when both rear lights and the wiring need to be refreshed at the same time rather than replacing one lamp at a time.

Maintenance and care

After launching in saltwater, rinse the trailer lights and rear crossmember with fresh water and allow the trailer to drain before storage. Periodic checks of the ground connection, harness routing, lamp operation, and license plate bracket can help catch common trailer lighting issues before the next tow.
