Nilight 2.5" Round LED Marker Lights 4PC (2 Amber + 2 Red) 13-LED SMD, Flush-Mount, Sealed ABS

Nilight 2.5" Round Marker Light 4PCS delivers compact, low-profile amber and red LED clearance lighting designed for 12V trucks, trailers, RVs, and heavy equipment.

These flush-mount marker lights combine 13 high-efficiency SMD LEDs behind a reflective lens with a sealed ABS housing to give visible, durable marker and clearance illumination in wet and demanding road conditions. The set includes two amber and two red 2.5-inch lights, rubber grommets for a snug mount, and simple 2-prong wiring for straightforward electrical hookup.

How bright and reliable are these 13-LED marker lights?

The Nilight lamps use 13 compact 2835 SMD diodes per unit and a reflective AS lens to maximize light output for their size, creating strong visibility at night and in poor weather. The LED array runs cool and resists dimming over time compared with incandescent bulbs.

• 13 x 2835 SMD LEDs per light for concentrated brightness.
• Reflective lens improves beam spread and visibility.
• Low power draw suitable for 12V systems.
• Designed for long-lasting, consistent illumination.

What does installation look like for a 2.5" flush-mount marker light?

Installers cut a 2.8-inch mounting hole, seat the supplied rubber grommet to cushion and seal the fixture, then push the light into place and connect the white ground and black positive wires. The compact footprint and two-wire hookup speed up retrofit or replacement jobs.

• Required cutout: 2.8 inches diameter.
• Includes rubber grommets for a tight fit and vibration resistance.
• Simple 2-prong wiring: white = ground, black = positive.
• Flush mount keeps lights protected from snags and debris.

Will these lights hold up to rain, road spray, and rough use?

Nilight builds the lens from AS plastic and the base from ABS, fused using ultrasonic bonding to achieve a sealed construction that minimizes water ingress. That combination makes the lights suitable for exterior vehicle use where moisture and road grime are common.

• AS lens plus ABS shell for impact and weather resistance.
• Ultrasonic sealing reduces risk of leaks and corrosion.
• Fully enclosed design helps prevent internal moisture buildup.
• Durable for daily driving and fleet use.

Which vehicles and applications are these marker lights best for?

These 2.5-inch marker lights function as clearance, indicator, or marker lamps on 12V vehicles. They suit heavy-duty trucks, pickups, trailers, tractors, dump trucks, buses, vans, and RVs where small-but-visible side, rear, or profile lighting is required.

• Ideal for trucks, trailers, RVs, buses, and agricultural equipment.
• Use as side markers, clearance lights, or auxiliary indicators.
• Works with standard 12V vehicle electrical systems.
• Supplied in mixed color pack: 2 amber + 2 red for versatile placement.

Who is this for? Drivers, fleet managers, and DIY mechanics who need compact, energy-efficient marker and clearance lights that are easy to mount and designed for outdoor vehicle use will find this Nilight 4-piece set practical. It suits retrofit projects, routine replacements, or upgrades where reliable visibility and a sealed, low-profile installation are priorities.
