Partsam 12ft Red/Amber Double Face LED Trailer Light Bar

In this review of the Partsam 12' Red/Amber Double Face LED Trailer Light Bar, the bottom line is simple: this is a durable, DOT-compliant dual-face light bar aimed at truck and trailer owners who need clear front amber and rear red stop/turn/tail signaling on a single pedestal installation. The review finds it most useful for operators who want a neat, low-profile retrofit with solid looks and easy mounting hardware, while noting the lights are hard-wired and have reported functionality issues for a minority of buyers.

Key Features

• Dual-face design: Amber LEDs face forward and red LEDs face rearward so one pedestal serves both marker and stop/turn/tail functions and reduces the number of separate fixtures.
• 20 LED array: Each 12' bar contains 20 LEDs behind colored lenses to deliver bright, visible signaling for heavy and medium duty trucks.
• Double metal stud mounts: The pair of metal studs are spaced about 2-1/16' apart for secure pedestal mounting on fenders or trailer bodies.
• Pre-wired harness: The unit uses a simple three-wire hard-wired setup (white ground, red turn, black marker) for integration with existing vehicle wiring.
• DOT compliant: Built to meet street-legal lighting requirements so it is suitable for on-road use with common truck makes.

Who It's For

This light bar is best for professional drivers and fleet owners who need a compact dual-function pedestal light for semi trailers or dump trucks and who are comfortable with hard-wiring parts into vehicle wiring. It suits users who want a chrome-plastic, low-profile fixture that presents a clean, factory-like appearance.

It is not ideal for buyers looking for plug-and-play replacement modules or those unwilling to troubleshoot electrical issues; a few customers reported units that did not function out of the box, so owners should be prepared to test wiring and connections after installation.

Pros & Cons

Pros

• Good visible output from the 20 LED array for both amber and red faces, improving daytime and nighttime conspicuity.
• Versatile double-face pedestal reduces the number of separate fixtures and simplifies aesthetic placement on fenders or trailer edges.
• Robust mounting with double metal studs provides solid mechanical attachment for heavy-duty use.
• DOT compliance means the lights meet legal requirements for on-road signaling.

Cons

• These are hard-wired units, not plug-and-play, which increases installation complexity for some users.
• Some customers reported functionality problems with a minority of units, so buyers should verify operation immediately after installation.
