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

Nilight 3/4" Round Marker Light 10PCS delivers dual-brightness amber LED lighting in a sealed, flush-mount package for trucks, trailers, RVs and boats.

These compact 3/4-inch marker lights combine three high-output 3030 SMD LEDs with a three-wire upgrade that supports two brightness levels and reliable metal connectors. Designed for flush mounting with a rubber grommet, each lamp is fully sealed with hard glue on the circuit board to meet IP68-level waterproofing. The kit includes ten lights and compatible connectors, making it easy to outfit or replace multiple clearance, marker, or signal positions on 12V vehicles and equipment.

How do the two brightness levels work and why are they useful?

Each light has separate circuits for low and high outputs so a single fixture serves both marker/clearance lighting and brighter turn/signal functions. Wiring uses three leads—ground, low, and high—so your wiring harness or controller can switch modes without changing fixtures.

• Low brightness: steady marker/clearance illumination that conserves power.
• High brightness: flashing or steady output suitable for turn or indicator signaling.
• Three-wire hookup: white = ground, black = low, red = high for straightforward installation.

What do I need to install these flush-mount lights?

Installation is quick with the included rubber grommets: drill a 0.78" circular hole, press in the grommet, seat the lamp, and connect the three wires. The metal connector interface fits standard 4mm housings, reducing adapter needs.

• Hole size: prepare a 0.78-inch circular opening for the grommet.
• Mount: push rubber grommet then lamp until flush with surface.
• Wiring: connect white to ground, black to low, red to high; use insulated connectors for weatherproofing.

How durable and weather-resistant are these lights?

Nilight sealed each lamp completely and added transparent potting material over the rear circuit to protect connections and LEDs from moisture and vibration. The robust construction meets IP68-level waterproofing, making the lights suitable for submerged or heavy-weather exposure in demanding applications.

• Full sealing and epoxy potting on circuit board to prevent water ingress.
• IP68-rated for dust-tight and long-term submersion resistance.
• Sturdy metal connectors and vibration-resistant design for vehicle use.

Which vehicles and applications are these marker lights best for?

These lights are designed for any 12V vehicle or equipment that requires compact, bright amber markers or turn indicators. Their small size and flush mount make them especially useful where space is tight or a low-profile look is preferred.

• Commercial trucks, trailers, and tractor units for marker and clearance lighting.
• RVs, campers, and buses for side marker and indicator positions.
• Boats, utility vehicles, and specialty equipment that need waterproof amber lighting.

Who is this for? Installers, fleet managers, and vehicle owners who want a compact, multi-function amber light solution will appreciate this Nilight 10-pack. It suits anyone needing corrosion-resistant, submersible marker or signal lights for 12V systems where a low profile, dual-intensity fixture simplifies wiring and reduces part count. The pack is also convenient for refurbishing multiple points on trailers, RVs, or marine craft, offering uniform brightness and reliable sealing across all installed locations.
