Nilight 16" LED Trailer ID Marker Light Bar, Red 2-Pack — Weatherproof Multi-Function Tail/Stop

The Nilight 16" LED Trailer ID Marker Light Bar is a sealed, multi-function red LED light bar sold as a 2-pack for clear trailer identification and combined tail/stop/turn signaling.

Built for 12V trailer and truck applications, these 16-inch red LED marker bars provide high- and low-brightness LED outputs in a weatherproof polycarbonate housing. Each bar includes integrated wiring for ground, low/tail, and high/stop outputs and arrives with mounting hardware so you can flush- or bracket-mount the units on trailers, RVs, or work vehicles.

How does this light bar handle wet and rough conditions?

The Nilight light bar is designed for harsh environments: the front polycarbonate lens is sonically welded to the housing and the back wire lead is sealed with adhesive to keep moisture and debris out. That sealing method helps prevent corrosion and electrical faults in wet or dusty conditions.

• Sonic-welded polycarbonate lens for strong, watertight front seal
• Adhesive-sealed back wire lead to reduce water ingress
• Durable housing materials resist impact and road vibration

What electrical functions and wiring does the light bar offer?

Each light bar contains 11 LEDs with two brightness settings to serve multiple trailer lighting roles: low-brightness for tail/parking, and high-brightness for brake/stop. Wiring is color-coded for straightforward installation so you can connect ground, low-brightness, and high-brightness circuits without confusion.

• 11 LEDs per light delivering high and low brightness outputs
• White wire = ground; black wire = low brightness/tail light
• Red wire = high brightness/brake light

How do I mount the bar on my trailer without damaging the frame?

Nilight provides two practical mounting approaches to suit different trailers: a flush-mount option that uses the existing or a drilled center hole, and a no-drill option using a bracket or added washers to secure the ends. Screws and a hardware pack are included to simplify a clean installation.

• Flush-mount by routing wires through a center hole and fastening both ends
• Use provided screws and hardware for secure installation
• Add washers or a mounting bracket to avoid drilling into the housing or frame

Which vehicles and applications are these light bars suitable for?

These 16-inch marker bars are made for 12V systems and fit a wide variety of trailers and heavy-duty vehicles. Typical uses include cargo trailers, semi trailers, boat trailers, RVs, horse trailers, and utility or work trucks that need distinctive red identification and combined tail/stop/turn functionality.

• Compatible with 12V heavy-duty trucks and trailers
• Ideal for cargo, boat, travel, horse, and utility trailers
