Note: Each option is designed for identification and safety lighting on wide trailers (80″ or wider) or as a secondary rear marker. The choices vary in length, mounting style, and regulatory compliance to fit different vehicle and trailer configurations.
Nilight 14.2″ 9 LED Trailer Light Bar
This 14.2-inch ID marker light uses 9 upgraded Piranha LEDs to deliver wider lighting angles and higher intensity. It is designed for trailers 80 inches or wider that require clear rear identification. The light is mounted on the top or between taillights to increase visibility for oncoming traffic. It is built with IP67 waterproof housing and a corrosion-resistant black base bracket for all-weather use.
Best for: Wide trailers that need conspicuous daytime and night-time visibility. Choose this if you prioritize a compact, bright rear marker with robust weather sealing.
Caution: Ensure the mounting location accommodates a 14.2-inch bar and that wiring is protected from road debris and moisture.
TRUE MODS 15″ 3 Red 9 LED ID Bar
This 15-inch red LED light bar features 9 LEDs across three marker lights and is designed for 80″ wide trailers requiring identification lighting. It carries DOT FMVSS 108 compliance and IP67 submersible rating for all-weather reliability. The unit can be mounted on top of the trailer or between taillights to maximize visibility.
Best for: Operators needing DOT-compliant identification with robust waterproofing. It’s a strong choice for fleets that require regulatory alignment and reliable performance in wet environments.
Caution: Check local laws to confirm lamp placement on non-standard trailer configurations and ensure proper drainage in mounting areas to avoid water accumulation.
TRUE MODS 16″ Red LED ID Bar
This 16-inch light bar provides brake, turn, and park functionality and uses a reflective lens design to meet rear reflector requirements. It ships with clear back markings for easy installation, including ground, tail, and stop indicators. The DOT-compliant unit is suitable for trailers requiring multiple signaling modes and visible rear lighting.
Best for: Trailers needing a multifunction rear light that doubles as a reflectivity aid. Opt this if you want a single unit handling braking and signaling with straightforward wiring.
Caution: If your trailer already has separate rear lights, confirm electrical compatibility and avoid duplicating lighting circuits.
Buyers Products 17″ 3 Light ID Bar
This 17-inch polycarbonate ID bar uses nine LEDs distributed across three marker lights. It is designed to meet FMVSS/CMVSS 108 regulations for trucks and trailers. The installation is straightforward with a blunt cut lead and ring terminal. It has a low current draw (0.120 amp at 12 volts) for efficient power use and comes with a limited lifetime warranty.
Best for: Fleet owners and operators prioritizing regulatory compliance, low power consumption, and a robust warranty. It is well suited for long-haul trailers and commercial fleets.
Caution: Polycarbonate components can be affected by UV exposure over time; consider protective housings or shade during prolonged outdoor use._
Partsam Red Clearance ID Bar Marker Light
This is a 350mm x 30mm x 26mm red LED identifier bar with three LED marker lights totaling nine LEDs. It uses a stainless steel black bracket base and includes mounting hardware. The IP67 waterproof rating ensures weather resistance, and the unit is DOT approved for wide trailers. The design emphasizes corrosion resistance and a straightforward single-wire power approach with grounded mounting hardware.
Best for: Trailers over 80″ wide that require sturdy stainless steel construction and reliable weather sealing. It’s a good match for challenging climates and long-term outdoor exposure.
Caution: The single-wire power approach means correct polarity and grounding are essential to avoid miswiring or malfunction.
Buying Guide: Key Purchase Considerations
When choosing trailer rear identification lights, consider width, regulatory compliance, weather resistance, and installation simplicity. The following questions help match a product to your setup.
- Is the trailer width 80 inches or wider, requiring an identification light bar?
- Do you need DOT/FM VSS 108 compliance or reflectivity requirements for legal on-road use?
- What is your mounting preference—top-mounted, between taillights, or integrated into existing lighting?
- How important is IP rating and weather sealing for your environment (IP65 vs IP67)?
- What is the target power draw and wiring complexity for your trailer’s electrical system?
- Are you seeking a multi-function unit (brake/turn/park) or a simple clearance light bar only?
Additional Considerations
- Durability: Stainless steel brackets and corrosion resistance are important for long-term exposure to road salts and moisture.
- Installation: Look for units with clear back labeling and simple ground-and-power wiring to reduce installation time.
- Maintenance: IP67 or higher housings reduce water ingress; consider units with removable covers or drainage features.
FAQ
- Q: Do I need these lights for all trailers or just wide ones?
A: Wide trailers (80″ or wider) typically require identification lights for added visibility and regulatory compliance. - Q: What does IP67 rating mean?
A: IP67 means the light is dust-tight and protected against immersion in water up to 1 meter for 30 minutes. - Q: Can I install these myself?
A: Yes, most identification bars are designed for straightforward installation with basic wiring and mounting hardware. - Q: Do these lights affect trailer electrical systems?
A: They have low current draws (often around 0.12 amps at 12V), which minimizes impact on vehicle electrical systems. - Q: Are these compliant with DOT/FM VSS 108?
A: Some options are DOT FMVSS 108 compliant; verify the model specifications before purchase. - Q: Can I replace just the marker section if it fails?
A: Many bars use modular LEDs or sections, but check the product’s replacement parts policy and warranty.
