Partsam 17" Red LED Identification Light Bar — DOT-Approved 3-Light 12V IP67 Sealed

Partsam's 17" red LED identification light bar is a DOT-approved, sealed 3-light assembly that provides bright, weatherproof marker illumination for trucks, trailers, and SUVs.

This low-profile 17-inch clearance light bar from Partsam is built to increase visibility for vehicles wider than 80 inches. The unit houses three lamp modules with a total of nine LEDs behind a durable red clear PC lens, and it meets DOT standards for identification lighting. Designed for 12V systems, the bar installs with two wires and a simple bolt pattern, offering an easy retrofit or replacement for F150, F250, F350, RAM, Silverado, Sierra, RVs, and multiple trailer types.

How bright and durable is this light bar for road use?

The bar uses three LED modules (three LEDs per module) to create a concentrated, high-output red signal that extends visibility in traffic and low-light conditions. The polycarbonate lens boosts light transmission and resists impacts while the sealed housing prevents moisture and dust intrusion.

• 9 total high-intensity LEDs for wide beam spread
• Red clear PC lens for strong light transmission and impact resistance
• DOT-approved design suitable for legal identification lighting
• IP67 sealed housing for water and dust protection

Will this fit my vehicle and how simple is installation?

The Partsam light bar is a universal 12V unit sized to fit most full-size pickups and trailers wider than 80 inches. Mounting uses two fasteners spaced to the specified hole distance, and wiring is straightforward with a two-conductor hookup: black to negative and white to positive.

• Overall dimensions: 430mm x 39mm x 43mm (16.93" x 1.54" x 1.69")
• Hole-to-hole distance: 405mm (15.94") for mounting alignment
• Two-wire connection: black = negative, white = positive
• Compatible with trucks, trailers, RVs, campers, and SUVs using 12V systems

How does the light bar stand up to weather and road conditions?

The assembly is rated IP67, which means it is dust-tight and can withstand temporary immersion in water. The sealed construction and corrosion-resistant materials protect internal electronics from snow, road spray, salt, and sand encountered in daily driving and towing.

• IP67 waterproof rating for reliable wet-weather performance
• Sealed against dust and debris for long-term dependability
• Robust lens resists cracking and UV degradation
• Designed to handle road vibration and environmental exposure

What specific uses and vehicle types benefit most from this light?

This identification light bar is ideal for any application that requires added rear or roofline visibility on wider vehicles and trailers. It can function as a center-mounted identification light, a side marker addition, or a replacement for cracked or dim OEM bars.

• Center or roofline identification light for trucks and trailers
• Replacement for broken or noncompliant factory marker lights
• Retrofit for campers, horse trailers, boat trailers, and RVs
• Useful on pickup trucks such as F150/F250/F350, RAM, Silverado, Sierra

Who is this for? Installers, fleet operators, and owners of full-size trucks or trailers who need a DOT-approved, easy-to-fit identification light will find this Partsam 17" LED bar useful. It suits DIY mechanics looking for a straightforward two-wire replacement, service shops updating worn marker lighting, and anyone who wants a compact, weatherproof solution that improves visibility without complex wiring or bulky hardware.
