What Trailers Is the LightCo 10590 Used On?

The 10590 marker light bar is commonly used as a rear identification light bar on trailers over 80 inches wide — a DOT-required lighting function for wide-body trailers. It is also widely used as a rear marker or clearance bar on enclosed trailers, flatbeds, and equipment trailers where a single bar-style light is preferred over individual marker lights.

Common Trailer Applications

Trailer Type	Application
Boat Trailers — Over 80" Wide	Rear identification bar — DOT required for trailers exceeding 80" in width
Enclosed Cargo Trailers	Rear marker / clearance bar — improves visibility and meets DOT marker requirements
Flatbed Trailers	Rear identification or clearance bar — common on wide flatbeds hauling equipment or machinery
Dump Trailers	Rear marker bar — withstands the vibration, impact, and debris exposure typical of dump trailer use
Equipment Trailers	Rear clearance / identification bar — frequently used on skid steer, excavator, and heavy equipment trailers
Utility Trailers — Over 80" Wide	Rear identification bar — satisfies federal clearance and identification requirements
Horse & Livestock Trailers	Rear marker bar — IP68 rating handles regular wash-down and outdoor exposure
Gooseneck & Fifth Wheel Trailers	Rear identification or marker bar — common on wide-body gooseneck trailers over 80"

DOT Identification Light Bar Requirement — What You Need to Know

Federal law (FMVSS 108) requires trailers over 80 inches wide to display a rear identification light bar — a cluster of three red lamps centered on the rear of the trailer at the highest practical mounting point. The LightCo 10590 satisfies this requirement in a single surface-mount unit, eliminating the need for three separate individual marker lights and their associated wiring.

Installation

The LightCo 10590 installs using standard surface-mount hardware — bolt it to the rear of your trailer at the highest practical point, centered on the trailer width. Connect to your trailer's running light circuit via the included lead wires. No special tools required.

Secure with included bolts or standard trailer hardware

Frequently Asked Questions

Is this light bar required on my trailer?
If your trailer is over 80 inches wide, federal law requires a rear identification light bar — three red lamps centered on the rear. The LightCo 10590 satisfies this requirement in a single unit.

Is the IP68 rating truly submersible?
Yes. IP68 is the highest standard waterproof rating, certified for continuous immersion beyond 1 meter. Combined with TecSeal urethane potting, the 10590 is one of the most water-resistant marker bars available.

Can this be used as a side marker bar?
The 10590 is designed primarily as a rear identification or clearance bar. For side marker applications, see our clearance and marker lights collection.

Will this work with my existing trailer wiring?
Yes. The 10590 connects directly to a standard trailer wiring harness via the running light / brown wire circuit. Compatible with 4-pin flat and 5-wire harness systems.
