Nilight 3/4" Round Marker Light 10PCS Red LED 3 Connectors

Nilight 3/4" Round Marker Light 10PCS are compact, sealed red LED lights with three-wire high/low brightness for use as brake, stop, turn, marker and clearance lights.

These Nilight 3/4" round marker lights pack three 3030 SMD LEDs into a rugged, IP68-sealed housing and use an upgraded three-wire connector for separate high- and low-brightness functions. Designed for flush-mount installation with a rubber grommet, the set of ten lights fits most 12V vehicles including trucks, trailers, RVs and boats. The lights provide two distinct brightness levels—high for brake/stop/turn signaling and low for marker/clearance indication—while the sealed construction guards the LEDs and wiring from moisture and debris.

How do these lights deliver both brake and marker functions?

The Nilight round lights use a three-wire design that separates ground, low brightness and high brightness circuits so a single fixture can serve dual roles. Wiring white to ground, black to low brightness and red to high brightness lets your vehicle controller or wiring harness trigger the correct intensity for marker versus brake signals. This approach reduces the need for multiple fixtures and simplifies wiring on multi-function trailers and RVs.

• Three-wire layout: white (ground), black (low), red (high).
• High mode suitable for brake/stop/turn signals.
• Low mode suitable for marker/clearance/position lighting.
• Works with standard 4mm connectors and common vehicle harnesses.

What makes these lights durable for outdoor and marine use?

Each Nilight lamp is fully sealed and reinforced with transparent hard glue at the circuit board back to protect solder joints and wires from water intrusion. The IP68-rated construction keeps the LEDs and connections dry in heavy rain, splashes and harsh environments. Durable materials and a snug rubber grommet provide a reliable flush-mount fit that resists vibration and road shock.

• IP68 waterproof rating for long-term outdoor exposure.
• Sealed circuit board with protective hard glue backing.
• Rubber grommet for secure flush mounting and vibration resistance.
• Robust construction suited for road and marine conditions.

How easy is installation for DIY or professional fit-up?

Installation is straightforward: drill a 0.78" (approximately 3/4") hole, press in the supplied rubber grommet, snap the light into place, then connect the three wires to your vehicle wiring. The upgraded metal connectors accept common 4mm terminals, making the lights compatible with many existing harnesses. Because they are pre-sealed and compact, these lights are suitable for quick replacements or new installs on trailers, RVs, tractors and boats.

• Hole size required: 0.78" diameter for flush mount.
• Supplied rubber grommet included for snug fit.
• Accepts 4mm connector terminals for quick wiring.
• Simple three-wire hook-up: white ground, black low, red high.

What light output and visibility can I expect?

Each round lamp contains three 3030 SMD LEDs that deliver clear red illumination in two intensity levels. The low setting provides steady marker/clearance visibility while the high setting flashes or brightens for brake or turn signaling, improving attention from following drivers. The compact optics offer wide-angle visibility suitable for perimeter marker and signaling duties.

• Three 3030 SMD LEDs per lamp for bright, consistent red light.
• Two brightness levels: low for markers, high for brakes/turns.
• Wide-angle visibility for roadside and trailer use.
• Designed for 12V DC vehicle electrical systems.

Who is this for: These Nilight 3/4" round red LED lights are ideal for trailer and RV owners, truck fleets, boat builders, landscapers and DIY mechanics who need compact, multi-function marker and brake lights with reliable waterproofing. Choose this 10-piece set if you want versatile, flush-mount LED fixtures with separate high/low circuits for clean wiring and clear signaling across a range of 12V vehicles and equipment.
