Nilight 3/4" Round Marker Light 10PCS delivers bright red LED clearance and marker illumination in a compact, fully sealed flush-mount design for trucks, trailers and RVs.

These compact 3/4-inch round marker lights combine three 3030 SMD LEDs per lamp with an IP68-rated sealed housing and pre-attached 9.84" wires with upgraded metal connectors. Supplied as a 10-piece set, they are engineered for quick flush installation using the included rubber grommets and are compatible with common 4mm connectors. They serve as marker, clearance, or indicator lights for 12V DC vehicles such as trucks, trailers, buses, RVs, campers and specialty equipment.

How bright and reliable are these lights for day and night visibility?

The lights use 3pcs 3030 SMD LEDs that produce a clear, vivid red output suitable for marking and signaling in both daylight and darkness. The LED configuration balances low power draw with high visual noticeability, improving safety without heavy current demand.

• Three 3030 SMD LEDs per lamp for consistent red output
• Low current consumption suited to 12V DC systems
• Designed to be clearly visible in various lighting conditions

What makes installation fast and what wiring do I need?

Each light comes with a rubber grommet for a simple flush-mount fit into a 0.78" diameter hole. The unit has two pre-attached 9.84" (22AWG) wires and upgraded metal connectors that fit standard 4mm connector systems, simplifying hookups on most vehicles.

• Drill a 0.78" hole, press in grommet, then insert the light
• White wire = ground, black wire = marker/clearance circuit
• Upgraded metal connectors compatible with 4mm connectors for secure joins

How durable and weatherproof are these marker lights?

The housing is fully sealed and protected with transparent hard glue over the circuit board, preventing water intrusion and protecting the wiring junction. The construction meets IP68 standards, making the lights suitable for wet, dusty, or road-spray environments.

• Fully sealed housing with potting over the PCB to block moisture
• IP68-rated for immersion and heavy-weather resistance
• Robust wiring strain relief and metal connectors to reduce failures

Which vehicles and positions are these lights best suited for?

These compact round marker lights are versatile for many 12V applications: use them as side marker lights, clearance lights, or small indicators on trailers, trucks, RVs, buses, tractors and boats. Their small footprint makes them ideal where space is limited or a low-profile, flush look is desired.

• Suitable for trucks, trailers, RVs, buses, campers and specialty vehicles
• Used as clearance, marker, or auxiliary indicator lights
