Partsam Boat Trailer Guide Lights 2-Pack — DOT-Approved LED Post Lights, IP67 Waterproof, Integrated Reverse

Partsam 2-pack LED boat trailer guide lights are DOT-approved, IP67 waterproof post lights with integrated tail, turn, brake and reverse functions to improve night visibility and make loading easier.

These patented guide-on post lights are designed for boat trailers and other towing needs where clear side-marker and reversing illumination matters. Each lamp uses advanced SMD LEDs for brighter, more consistent output than standard LEDs. The compact units mount to common 2" PVC guide posts (2-3/8" outside diameter) and include wiring for full brake/turn/tail/reverse operation plus simple top guide illumination.

How do these lights increase safety when towing at night?

The Partsam guide lights combine multiple lighting functions in a single, visible unit so other drivers can more easily judge your trailer's width and motion. Bright SMD LEDs provide clearer indication of braking and turning, while the reverse lamp lights the area behind the trailer when backing down ramps.

• DOT-approved for on-road visibility and compliance.
• High-brightness SMD LEDs for clearer signaling.
• Integrated reverse light illuminates the ramp or ground behind the trailer.
• Top guide lamp marks each post for easier trailer alignment.

Will these fit my trailer posts and how hard are they to install?

Installation is straightforward on standard guide-on posts with approximately 2-3/8" outside diameter (2" PVC). The lights include clearly labeled wires for ground, low/high brightness and reverse, plus spare mounting screws. No proprietary tools are required for most installs.

• Fits standard 2" PVC guide posts (2-3/8" outside diameter).
• Wiring: white = ground; black = low brightness; red = high brightness; blue = reverse.
• Top guide light wiring: white = ground; black = positive.
• Spare screws included to secure assemblies into the housing.

How durable are these lights near water and road conditions?

Partsam designed these guide lights for the marine environment with an IP67 waterproof rating, meaning they resist immersion and heavy splashing. The robust housing and sealed electronics help them withstand trailer vibrations, saltwater exposure and typical road debris.

• IP67 waterproof rating for immersion resistance and splash protection.
• Sealed design to protect LEDs and wiring from moisture.
• Durable construction to handle trailer vibration and road debris.
• Patented assembly that maintains brightness over time.

What functions do the lights perform and how do they operate?

Each unit provides full rear lamp functionality—tail light, brake light and turn signal—plus a dedicated reverse lamp and a top guidance lamp for the post. The colored wiring makes it simple to connect each function to your trailer or tow vehicle wiring harness.

• Full-function tail, brake and turn signals for road use.
• Reverse lamp illuminates during backing maneuvers.
• Top guide light marks trailer posts for alignment on ramps.
• Included wiring scheme simplifies electrical hookup.

Who is this for: These Partsam guide post lights are suited to boat owners, marina operators and anyone who tows trailers in low-light conditions. They are a good match for fishing boats, ski boats, sailboats and utility trailers that use 2" PVC guide posts and need brighter, waterproof rear and reverse lighting to simplify night loading and improve road-side awareness.
