Partsam 12V Submersible Square LED Trailer Lights, Black/Clear Pair — IP68 Waterproof, Stop/Turn/Tail/Reverse

Partsam 12V Submersible Square LED Trailer Lights are a weatherproof left-and-right lamp pair that combine stop/turn, tail, side marker, reverse backup and license illumination for trailers under 80". These low-profile square lights are built to survive wet, rough towing conditions while delivering clear red and white LED signaling for safer on-road and backing visibility. Each lamp uses multiple diodes behind an impact-resistant PC lens and ABS housing, with an IP68 waterproof rating to keep circuits protected from immersion and spray. The set includes gaskets and mounting screws for a straightforward retrofit; a separate wire harness is required for some vehicles.

How do these lights perform in wet or off-road conditions?

The Partsam lights are engineered for weather exposure and occasional immersion. An IP68 rating plus sturdy ABS housing and impact-resistant polycarbonate lenses guard the LEDs and wiring from water ingress and physical wear.

• IP68 waterproof rating blocks water and dust at immersion levels.
• ABS housing resists impact and road vibration.
• PC lens reduces cracking and abrasion from debris.
• Sealed wiring entry reduces corrosion risk over time.

What wiring connections and functions should I expect?

Each lamp uses color-coded wires to separate ground, brake/turn, running/tail, and reverse circuits so you can integrate with standard trailer wiring or a dedicated harness. The left lamp includes a white license/backup LED function; both lamps provide tail and side marker outputs at low brightness.

• White wire = ground connection for the lamp ground.
• Yellow/green wire = high-brightness stop/turn signal feed.
• Brown wire = low-brightness running/tail/side marker/license plate feed.
• Blue wire = reverse/backup light activation.

What are the lighting outputs and physical differences between left and right units?

The two-square set balances red signaling diodes with white backup diodes for multifunction use. The left unit has a total of 21 diodes (13 red and 8 white) and includes the license plate light, while the right unit has 18 diodes (10 red and 8 white).

• Left lamp: 21 diodes — 13 red (signal/tail) + 8 white (backup/license).
• Right lamp: 18 diodes — 10 red + 8 white for backup illumination.
• Both units act as stop/turn, tail/side marker, and reverse lights.
• Clear lens and black bezel for modern, low-profile styling.

How easy is installation and what’s included?

The package contains two square tail lights, rubber gaskets and mounting screws plus wiring color guidance for a fast swap. A separate wire harness is not included, so plan to use your trailer’s existing harness or purchase the correct harness for plug-and-play convenience.

• Included: two lights, gaskets, mounting screws, wiring color guide.
• Not included: wire harness — may require purchase or reuse of existing harness.
• Mounting: surface-mount with gasket to prevent water intrusion.
• Suitable for trailers under 80", trucks, tractors and dump trailers.

Who is this for These Partsam square LED lights suit trailer owners, small-fleet operators and DIY mechanics who need a durable, multifunction lighting solution for boats, utility trailers, enclosed trailers and light trucks. Choose this set if you want bright, low-profile LEDs with clear backup illumination and a waterproof build for regular road use or wet environments — just plan for the correct wiring harness for your vehicle.

FAQ

Q: Are these lights fully waterproof for boat trailers?

A: Yes. They carry an IP68 rating designed to resist immersion and heavy spray, making them suitable for boat and wet-environment use.

Q: Does the set include a wiring harness?

A: No. The package includes lights, gaskets and screws but not a wire harness; you can reuse your trailer harness or buy one separately.
