Partsam 17" Red LED Truck & Trailer Identification Light Bar — DOT Approved, IP67 Waterproof, 3-Light 12V

Partsam's DOT-approved 17-inch red LED identification light bar is a sealed, three-light 12V replacement designed to boost visibility on trucks and trailers wider than 80 inches.

This compact, rugged light bar provides a clear, bright marker that meets DOT requirements for wide trailers and pickup applications. Built with nine high-output LEDs behind a durable red PC lens and an IP67-rated sealed housing, it resists water, dust, and road grit while delivering a wide spread of red light. The bar is compatible with a broad range of 12V vehicles, and its simple two-wire hook-up makes swapping in a reliable identification light quick and straightforward.

How will this light bar improve night and low-visibility driving?

The Partsam 17" identification bar increases the visible outline of your vehicle, helping other drivers judge width and position in dim conditions. The nine LEDs produce a steady, evenly distributed red signal that cuts through fog, rain, and darkness. Because it mounts high and spans nearly 17 inches, it clarifies vehicle edges better than smaller single lamps.

• Three LED modules, nine total LEDs for broader illumination
• Red clear polycarbonate lens for high light transmission
• 17" length suited for trailers wider than 80"

Is this light durable enough for heavy-duty and marine environments?

Yes—the light bar is built to withstand harsh conditions. The sealed housing is rated IP67, keeping out dust and allowing temporary immersion in water without damage. Its robust lens resists chips and yellowing, so it maintains brightness over time even on work trucks and boat trailers.

• IP67 waterproof rating for rain and splash resistance
• Impact-resistant red PC lens resists road debris
• Sealed construction prevents corrosion and ingress of contaminants

Which vehicles and mounting locations are suitable for this 17" LED bar?

The bar is a universal 12V accessory intended for trucks, pickups, trailers, RVs, and SUVs where an identification or marker bar is needed. Its size and mounting hole spacing make it ideal for top-of-body clearance mounting or centered between taillights to emphasize vehicle width.

• Fits 12V systems: F150/F250/F350, RAM 1500/2500/3500, Silverado, Sierra, and many trailers
• Mount on trailer roofline, truck cab top, or between rear lights
• Hole spacing 405 mm (15.94") for standard mounting brackets

How simple is installation and electrical hookup?

Installation is straightforward: predrilled holes and a two-wire connection let you replace an existing bar or add a new marker quickly. Black is the negative/ground lead and white is the positive feed. Basic hand tools and a sealed wiring connector are all you typically need.

• Light dimensions: 430 x 39 x 43 mm (16.93" x 1.54" x 1.69")
• Mounting hole distance: 405 mm (15.94") for easy alignment
• Two-wire hookup: black = negative, white = positive

Who is this for? If you drive or tow wide loads, manage a fleet, or simply want a reliable, DOT-approved marker that holds up to weather and road debris, the Partsam 17" red LED identification bar is a practical upgrade. It's aimed at owners of full-size pickups, work trucks, trailers, RVs, and anyone needing a compliant, long-lasting visibility solution without complex wiring or custom brackets.
