Partsam 17" Red LED Truck & Trailer Identification Light Bar - DOT Approved, IP67 Sealed, 3-LED Modules

Partsam's DOT-approved 17-inch red LED identification light bar is a sealed, three-light assembly designed to increase visibility on wide trucks and trailers and serve as a direct 12V replacement for many pickups and RVs.

This compact, weatherproof light bar fits vehicles and trailers wider than 80 inches and offers a bright, durable LED solution for identification and side-marker needs. Built with three clustered LED modules (nine LEDs total) and a red clear polycarbonate lens, the unit meets DOT requirements while resisting impact, dust, and water. It installs with a simple two-wire connection and comes in a low-profile housing sized to mount on roofs, tail sections, or between taillights.

How bright and durable is the Partsam 17" identification light bar?

The light bar uses three LED modules with three LEDs each, delivering a high-output, evenly spread red signal that improves detection in traffic. Its red clear PC lens promotes strong light transmission while resisting cracking and discoloration from sun exposure. The housing is sealed to IP67 standards so it keeps functioning through rain, splashes, and light immersion.

• 9 total LEDs for broad, consistent illumination
• Red clear polycarbonate lens for high transmission and impact resistance
• IP67 sealed housing to block dust and water
• DOT-approved design suitable for identification lighting

Will this light bar fit my truck or trailer and how is it installed?

The bar is 430mm (16.93") long and intended for trailers or vehicles wider than 80"; hole-to-hole spacing is 405mm (15.94") so it lines up with common mounting points. It connects with two wires — black negative and white positive — making it compatible with standard 12V vehicle wiring. Basic drilling and fasteners or surface-mount methods are typical installs; ensure you follow local wiring and safety regulations.

• Overall size: 430 x 39 x 43 mm (LxWxH)
• Mounting hole distance: 405 mm (15.94")
• Two-wire hookup: black negative, white positive

What vehicle types and uses are suitable for this LED marker bar?

The Partsam light bar is a universal 12V accessory that works across trucks, pickups, RVs, campers, horse trailers, boat trailers, and other tow vehicles. It functions as an identification light bar, side marker, or clearance lamp where extra red visibility is required. Because it's low profile and sealed, it’s especially useful on vehicles exposed to road spray, salt, or off-road debris.

• Compatible with F150/F250/F350, RAM 1500/2500/3500, Silverado, Sierra and similar models
• Suitable as top-mount or between-taillight placement
• Works on campers, travel trailers, horse and boat trailers
• Good choice for salt-prone or wet environments due to waterproofing

How weather-resistant and long-lasting is the assembly?

Engineered with an IP67 rating, the sealed light bar endures rain, splashes, snow, and dust without letting moisture reach the LEDs or wiring. The polycarbonate lens tolerates UV exposure and road debris better than standard plastics, helping preserve output and appearance over time. Routine inspection of the mount and wiring will keep the unit performing reliably for years.

• IP67 protection against water and dust ingress
• Red clear PC lens resists UV and impact damage
• Sealed housing prevents corrosion from road salt and grime
• Designed for long-term outdoor exposure and heavy-duty use
