Partsam 12V Submersible Square LED Trailer Lights (Red/White, Red Clear Lens)
The Partsam square LED trailer lights deliver a complete lighting package with 21 diodes on the left side and 18 on the right, covering stop/turn, reverse/backup, tail, side marker, and license plate lighting (left side only). Best for under-80″ trailers needing clear reverse illumination and robust waterproofing. The IP68 rating supports use in harsh weather. White is ground; yellow/green provides bright stop/turn; brown is tail/running; blue is reverse. Caution: left-side license plate light is included only on the left unit.
Best for: small to mid-size trailers that require multi-function lighting in a sealed housing. Why selected: high diode count and distinct color wiring for precise signaling and visibility. Limitation: installation requires attention to wire color roles and ground connection for proper operation.
Partsam 12V Submersible Square LED Trailer Lights (Red/White, Black Clear Lens)
This variant mirrors the prior design with a black clear lens housing, offering consistent multi-function LED performance (stop/turn, reverse, tail, side marker, license light on the left). Best for trailers where a dark housing blends with frame aesthetics. It shares the IP68 waterproof build and wiring guidance. Caution: ensure compatibility with your trailer’s ground and wiring harness to avoid lighting anomalies.
Best for: trailers needing a stealthy housing that hides wiring details. Why selected: identical LED layout and waterproofing with a visually different lens style. Limitation: license plate light is still left-side only, so plan accordingly for plate illumination on your setup.
Partsam 2Pcs Trailer Light Boxes Kit
This kit uses rust-resistant steel housing with 6″ oval LED tail lights and 2″ round red marker lights. Best for larger trailers or replacements where metal housings offer long-term durability. The kit includes grommets and wire connectors for a permanent weld-on installation. Caution: assembly requires welding or secure mounting on the trailer frame; edges and grommets must seal well to maintain IP65 water resistance.
Best for: heavy-duty trailers that see frequent outdoor use. Why selected: steel construction improves durability over plastic housings. Limitation: installation may be more involved compared to plug-and-play plastic options.
Nilight Trailer Tail Lights 2PCS 6 Inch
Nilight offers 6″ round tail lights with 23 LEDs per unit and a dual-purpose layout for tail/brake and reverse signaling. The design emphasizes weather sealing with a rubber edge and IP67 waterproof rating. Best for medium-sized trailers requiring high visibility in a compact form factor. Caution: while weatherproof, heavy exposure to direct submersion is not recommended beyond IP67 specs.
Best for: users needing compact, bright 2-piece tail lights for smaller boats or utility trailers. Why selected: strong LED count with dedicated reverse indicator and reliable waterproofing. Limitation: only 6″ units, which may not fit all trailer frames without adapters.
Partsam 12V Waterproof Square LED Trailer Tail Light Kit
This square light kit covers multiple signaling needs for under-80″ trailers and includes two stud-mounted lights, license bracket, wiring harness, and hardware. It is designed for IP67 waterproofing and submersible use, with left and right units having different LED counts for 7-function capability. Best for: boat or jet-ski trailers that require a complete, ready-to-install set. Caution: ensure the included harness length fits your trailer’s layout and that the license plate area aligns with the left-side light.
Buying Guide
Key considerations when choosing trailer lights with reverse functionality:
- Waterproofing and Durability: Look for IP67/IP68 ratings and rugged housings for marine or harsh-weather use. Submersible options prevent water ingress during launches or rain.
- Functionality: Confirm the combination of brake, turn, tail, running, and reverse lights. Some kits include built-in backup LEDs for safer reversing.
- Lens and Housing Style: Clear vs. colored lenses and black vs. clear housings affect visibility and aesthetics. Choose based on trailer color and mounting area.
- Wiring Configuration: Note wire color mappings (ground, stop/turn, running, reverse) to ensure compatibility with your trailer’s wiring harness.
- Installation Method: Weld-on steel housings differ from plug-in LED assemblies. Permanent mounting requires different tools and preparation.
- Size and Fit: Verify if the light size matches your trailer’s mounting holes and the overall frame dimensions to avoid fit issues.
- License Plate Illumination: Some units illuminate the license plate only on one side; plan plate placement accordingly.
FAQ
- Do trailer lights with reverse need a separate reverse fuse?
Many kits use dedicated reverse wiring, but check your vehicle’s fuse box and trailer harness for compatibility. - Is IP67 waterproof enough for boat trailers?
Yes, IP67 provides full immersion protection up to 1 meter for 30 minutes in most conditions. - Can these lights be wired to a 24V system?
Most are rated for 12V; using 24V requires a converter or a model designed for 24V systems. - Will reverse lights stay bright in direct sunlight?
LEDs provide consistent brightness during daylight, but visibility improves with high-contrast lenses. - Are license plate lights included on both sides?
Some models illuminate only the left side; plan plate placement accordingly if dual-side illumination is needed. - Do these kits come with mounting hardware?
Many include grommets, brackets, and wiring, but verify the exact contents before purchase.
