Nilight 2-inch Round Red LED Trailer Marker Clearance Lights — 5-Pack, Grommet-Mount, Polycarbonate Lens

Nilight 2-inch round red LED trailer marker clearance lights (5-pack) are compact, gasket-mounted LED marker and reflector lights built to increase visibility on trailers, trucks, RVs and other heavy vehicles.

These low-profile 2" LED markers combine bright quad-LED illumination with an integrated reflector lens and a simple grommet mounting system for quick replacement or upgrade of existing side marker and clearance lights. The set of five covers multiple mounting points on typical trailers and small trucks, while 22AWG, 2-prong wiring makes integration straightforward with 12V tail-light circuits.

How bright and visible are these marker lights at night?

The Nilight markers use four quality LEDs under a molded polycarbonate lens that both refracts and reflects light, increasing apparent brightness and side visibility. The result is a crisp red signal at night and enhanced daytime reflectivity when struck by other vehicle lights.

• 4 LEDs per housing for concentrated output
• Polycarbonate lens designed to reflect light back toward the source and oncoming drivers
• Compact 2" diameter keeps profile low while improving visibility

Is installation difficult and what wiring is required?

Installation is straightforward: position the supplied grommet in a pre-cut or existing hole, press the marker into the grommet, and connect the two wires to the trailers wiring. The white lead is ground and the black lead connects to a 12V tail/marker circuit; wiring uses 22AWG, 2-prong plug configuration for common compatibility.

• Grommet-mounted for tool-free seating into standard holes
• 22AWG two-wire lead: white = ground, black = 12V tail light
• Plug-style wiring fits many trailer harnesses and replacement locations

What mounting and durability features should I expect?

Each marker is designed for grommet mounting, which isolates the housing and provides a secure fit in round cutouts. The polycarbonate lens resists impact and weathering, and the sealed LED assembly minimizes moisture intrusion for reliable operation in road conditions.

• Grommet-mounted design for snug, vibration-resistant installation
• Durable polycarbonate lens for impact and UV resistance
• Sealed LED housing to protect against water and road grime

Can these lights be used on different vehicles and locations?

Yes — the 2" round red LEDs are suitable for a wide range of vehicles and mounting points where compact marker or clearance lights are needed. They serve as both active LED side markers and passive reflectors, making them versatile for trailers, trucks, buses and RVs.

• Applications: trailers, pickup trucks, tractors, dump trucks, buses, vans, RVs
• Works as powered marker light and passive reflector when unlit
• Five lights per pack cover multiple side/clearance positions

Who is this for: Owners and operators who need a compact, reliable, and easy-to-install set of red side marker/clearance lights for utility trailers, towing rigs, work trucks and recreation vehicles. This 5-pack is helpful for replacing worn lights, upgrading to LED efficiency, or stocking spare markers for fleet maintenance and roadside repairs.
