Partsam 17" Submersible LED Tail Light Bar - Clear Lens Red, 23-LED Stop/Turn/Tail for Trailers

Partsam's 17-inch submersible LED tail light bar is a heavy-duty, 23-diode red stop/turn/tail lamp with a clear lens built for trailers, trucks, RVs and work vehicles. This slim, weather-resistant light bar combines a clear cover with 23 high-output red LEDs to provide bright stop, turn and running illumination in a single, low-profile housing. Designed for hardwired installations, it includes three wires (white ground, red for brake/turn high-brightness, black for lower-brightness tail/running) and mounting holes spaced about 16.05 inches center-to-center for straightforward replacement or retrofit. Its 17.17" x 1.00" x 0.88" footprint fits many cargo trailers, semi-trailers, horse trailers and specialty vehicles where reliable rear signaling is needed.

How bright and visible are the LEDs on this light bar?

The bar uses 23 super-bright diodes arranged to deliver clear red signaling visible in daylight and at night. The clear lens helps focus output while keeping the overall profile thin and unobtrusive.

• 23 high-output red LEDs for strong stop/turn illumination
• Clear lens improves light transmission and visibility
• Designed for both daytime conspicuity and nighttime clarity

Will the light bar fit my trailer and how is it mounted?

This 17.17" lamp is compact with two mounting holes about 16.05" apart (center-to-center), which matches many common trailer hole patterns. The slim housing and standard mounting spacing make it an easy direct-replacement for many factory-installed or aftermarket rear light bars.

• Overall size: approximately 17.17" x 1.00" x 0.88"
• Screw holes: ~16.05" center-to-center for mounting
• Low-profile design fits flush on most trailer rear surfaces

How do I wire the Partsam 17" LED tail light bar?

Wiring is simple: the assembly uses three wires — white for ground, red for the high-brightness brake/turn circuit, and black for the low-brightness tail or running light. Hardwiring into existing trailer circuits follows standard trailer wiring conventions; use secure connectors and weather-resistant sealing for a long service life.

• White = ground (connect to chassis ground)
• Red = high-brightness brake/turn signal input
• Black = low-brightness tail/running light input

Is the light suitable for heavy-duty or exposed-use environments?

The bar is described as submersible and designed for heavy-duty applications like cargo trailers, dump trucks, boat trailers and special vehicles. The sealed housing and clear lens help protect the LEDs from moisture and road grime, making it appropriate for harsh field conditions when installed correctly.

• Submersible construction tolerates wet environments
• Sealed lens and housing resist water and contaminants
• Intended for heavy-duty vehicles: trailers, trucks, RVs, tractors
