Partsam 6" Rectangular Submersible LED Trailer Tail Lights Kit Red — 25ft 4‑Way Harness, IP68 Sealed

Partsam 6" rectangular submersible LED combination tail lights kit provides sealed, bright stop/turn/tail and license illumination for boat trailers and small utility trailers.

This all-in-one kit includes two sealed 6-inch rectangular LED combination lights, a 25-foot wiring harness with a standard 4-way flat connector, a license plate bracket, and stainless mounting hardware. Designed for trailer widths up to 80 inches, the IP68-rated housings are built to resist immersion and corrosion, making them especially suitable for boat trailers and wet environments. The lights combine rear stop/turn/tail, side marker, reflex, and one-side license plate illumination in a compact footprint.

How do these lights handle saltwater and submersion?

The housing and circuit board are fully sealed with no exposed screws on the lens, minimizing water entry points. Partsam performed submersion testing to ensure durability in marine conditions. Sealed construction reduces corrosion risk and maintains consistent illumination after repeated launches and retrievals.

• IP68-rated sealed circuit board for underwater resistance
• No lens screws to reduce leak paths
• Stainless steel mounting hardware to resist rust
• Designed for repeated exposure to wet environments

What lighting functions are included and how are they wired?

Each rectangular lamp delivers stop/brake, left or right turn, running tail, side marker, side reflex, and a license plate light on the driver side. The driver and passenger units have different diode counts to support the license plate lamp. Wiring follows standard trailer color codes for straightforward hookup to a 4-way flat connector.

• Driver side: 23 LEDs including license plate illumination
• Passenger side: 18 LEDs for stop/turn/tail and side marker
• Wiring: brown to tail, green to right stop/turn, yellow to left stop/turn, white to ground
• Included 25 ft 4-way harness for easy connection to vehicle plug

Will these lights fit my trailer and mounting needs?

The lights measure approximately 5.9" L × 3.35" W × 2.28" H and are intended for trailers under 80" wide; wider trailers require additional side clearance lights. The kit ships with a license plate bracket and stainless mounting fasteners to simplify installation on most metal or wooden trailer frames.

• Compact rectangular size fits many rear mounting locations
• Suitable for boats, utility trailers, campers, and small flatbeds
• Comes with mounting screws, bolt, and hardware for quick install
• Refer to Partsam low-profile kit if your trailer lacks side markers

How bright and reliable are the LEDs?

Partsam equips these lights with high-quality LED chips for clear visibility and long life compared with incandescent bulbs. The LED arrangement provides distinct brake and turn signals plus consistent running light output, while reduced current draw helps preserve towing vehicle electrical systems.

• High-output LED chips for strong signal visibility
• Separate diodes for brake/turn, running, and marker functions
• Lower power consumption and longer lifespan than incandescent
• Durable construction reduces maintenance and bulb changes

Who this is for: This Partsam kit suits boat owners, small trailer operators, and DIY trailer builders who need a dependable, waterproof lighting solution with easy 4-way connectivity. Choose this set if you want a submersible, corrosion-resistant tail light solution with included harness and hardware for a straightforward retrofit or new-install on trailers up to 80 inches wide. If your trailer lacks amber side markers and exceeds width limits, consider adding required clearance lights or selecting a dedicated low-profile kit.
