Partsam 17in 40-LED Waterproof Red Trailer Stop/Tail/Turn Light Bar, Pack of 2, IP65

Partsam’s 17" 40-LED red light bar is a waterproof, DOT-compliant stop/tail/turn and marker lamp designed to replace or upgrade trailer, truck, RV and utility vehicle rear lighting.

This slim, high-output light bar combines two rows of high-power Super FLUX LEDs behind a red lens and chrome plastic bezel to deliver a bright, long-lasting rear signal and marker solution. Sold as a pack of two, each bar measures approximately 17.12" long and is built for exposed vehicle use with IP65-rated water resistance. The assembly is wired for easy integration into standard trailer harnesses and arrives with mounting hardware to simplify fitting.

How bright and durable is this Partsam LED light bar?

The bar uses 40 high-power Super FLUX LEDs arranged in two rows, producing a strong flare for braking, turning and nighttime marker visibility. The chrome bezel and red lens offer both protection and a classic finish that resists corrosion and fading under normal road conditions.

• 40 Super FLUX LEDs per bar for high luminous output
• Two-row layout for broad light spread and redundancy
• Chrome plastic bezel protects LEDs and improves appearance
• IP65-rated housing for dust protection and water spray resistance

How do I wire and install the 17" tail light on my trailer?

Each Bar has three color-coded wires: white for ground, black for running/tail light, and red for brake/turn signals. Installation requires routing the wires through a drilled hole, sealing the entry, and fastening with the included nuts and bolts; typical installations take under an hour for one bar.

• White = ground; black = tail/run; red = brake/turn
• Drill wiring and mounting holes, use supplied bolts and nuts
• Seal wiring entry with silicone caulking to prevent moisture ingress
• Compatible with most trailers, trucks, RVs, buses and vans

Is this light bar compliant and suitable for road use?

Partsam markets this assembly as DOT-compliant for use as stop/tail/turn and identification lighting on trailers and commercial vehicles. While the bar is designed for legal road use, always check local and state requirements to ensure the mounting location and wiring meet regulations.

• Built for stop/tail/turn and marker functions
• Pack of two simplifies full-axle or symmetrical installs
• Chrome bezel improves visibility and style while protecting components
• Verify local vehicle codes before final installation

Who this is for: drivers and fleet owners who want a low-profile, high-visibility rear lighting upgrade for trailers, semi trucks, motorhomes, buses, utility trucks, horse and pickup trailers. It’s a practical choice for anyone replacing worn incandescent strips with LEDs, adding a cleaner finished look to rear assemblies, or upgrading to a weather-resistant option that reduces wiring complexity. Ideal for DIY installers and professional shops alike, the Partsam 17" LED light bars come ready with mounting hardware and straightforward wiring to get vehicles back on the road quickly.
