Nilight 3/4" Round Red LED Marker Lights 10-Pack — Dual-Brightness, IP68 Sealed

Nilight 3/4" Round Marker Light is a compact, fully sealed red LED lamp with dual-brightness outputs and a 3-wire connector designed for brake, stop/turn and marker lighting on 12V vehicles.

These 3/4" (0.78" hole) round marker lamps pack three high-output 3030 SMD LEDs into a rugged, IP68-rated housing. Each unit uses an upgraded three-wire layout (white ground, black low, red high) and metal connectors for reliable contact. The kit includes ten lights and rubber grommets for a clean flush mount, making them suitable for trailers, trucks, RVs, boats and other 12V applications where space is limited but visibility is essential.

How do the two brightness levels work and when would I use each?

Each light offers two distinct brightness modes: a lower-intensity setting for marker or clearance purposes, and a higher-intensity output for brake or stop/turn signaling. The three-wire design lets you feed a separate circuit for low and high outputs so the same lamp serves multiple functions without extra fixtures.

• High brightness (red wire): brake, stop, or turn signal output
• Low brightness (black wire): marker, clearance, or running light
• White wire: chassis ground connection for stable performance
• Compatible with 4mm metal connectors for secure wiring

How do I mount these lights to get a clean, flush installation?

Mounting is straightforward: drill a 0.78" round hole, press the rubber grommet into the panel, and then push the lamp into the grommet until it sits flush. The included grommet holds the lamp steady and protects wiring; no special brackets are required.

• Prepare a 0.78" diameter hole in your mounting surface
• Insert supplied rubber grommet, then seat the lamp into the grommet
• Connect white to ground, black to low, red to high circuits
• No external housing or bezel needed for flush look

Are these lights weatherproof and durable enough for heavy use?

The lights are fully sealed with added transparent resin over the circuit board and wire exits to prevent moisture intrusion and wire strain. With an IP68 waterproof rating and robust 3030 SMD LEDs, the fixtures tolerate wet, dusty and vibration-prone environments commonly found on trailers, trucks and marine craft.

• IP68-rated sealing for submersion and dust resistance
• Resin-filled rear for wire protection and longer lifespan
• Metal connector-compatible wiring for secure electrical contact
• Designed to resist road vibration, salt spray and weathering

Which vehicles and applications are these marker lights suitable for?

These compact red LEDs are intended for 12V systems and work well as brake/stop/turn signals or marker and clearance lights. They suit a wide range of vehicles and equipment where small-footprint, multi-function lighting is needed.

• Trailers, utility trailers, and flatbeds
• Pickup trucks, commercial trucks and semi trailers
• RVs, campers and motorhomes
• Boats, work vehicles, tractors and special-purpose equipment

Who is this for: Nilight's 3/4" round red LED markers are aimed at vehicle owners, fleet operators, and DIY mechanics who want compact, multi-function lighting that simplifies wiring and saves mounting space. If you need durable, weatherproof lights that combine marker and brake functions in a small bezel-free package—especially for trailers, RVs, boats or tight mounting locations—this 10-piece set offers an economical solution ready for direct flush installation.
