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

Nilight 3/4" round red LED marker lights are compact, sealed vehicle lights with dual-brightness 3-LED modules for marker and brake/stop applications.

These 10-piece red LED lights from Nilight combine a low-profile, flush-mount design with upgraded three-wire connectors and high-grade 3030 SMD LEDs to deliver visible daytime and nighttime signaling. Each lamp includes a rubber grommet for quick installation, an IP68-sealed housing for long life in harsh environments, and a three-conductor wiring layout that separates ground, low brightness (marker), and high brightness (brake/stop) functions.

How do these lights perform during day and night driving?

The Nilight lights use three 3030 SMD LEDs that provide two selectable brightness levels: a lower level for marker/clearance illumination and a higher level for brake or stop signaling. The dual brightness helps ensure the lights are visible without blinding other drivers while still providing a distinct, attention-getting signal when needed.

• 3pcs 3030 SMD LEDs per lamp for consistent output
• Low mode for marker/clearance visibility
• High mode for brake/stop/turn signal emphasis
• Clear lens for even light distribution

What makes installation fast and reliable on trailers or trucks?

Each light ships with a rubber grommet sized for a 0.78" hole for a flush mount fit that presses into place without special brackets. The wiring uses three insulated leads—white for ground, black for low brightness, and red for high brightness—plus upgraded metal connectors suited for 4mm terminals, simplifying hookups and reducing wiring errors.

• Press-fit rubber grommet for neat, flush installation
• 3-wire layout separates functions for simple wiring
• Upgraded metal connectors compatible with 4mm terminals
• Fits standard 12V DC vehicle electrical systems

Are these lights built to withstand weather and road conditions?

Nilight encases the circuit board in a transparent hard glue potting compound and fully seals the housing to prevent moisture and contaminants from entering. The IP68-rated construction resists water intrusion and corrosion, making these lights suitable for marine, agricultural, and heavy-duty road environments.

• Fully sealed housing with potting compound over the PCB
• IP68 waterproof rating for submersion and heavy water exposure
• Durable lens and housing materials resist road debris damage
• Reliable in salt, mud, and high-humidity settings

Which vehicles and uses are these lights best suited for?

Designed for 12V DC systems, the Nilight round LED markers work well on trucks, trailers, RVs, buses, tractors, campers, special-purpose vehicles, and boats. They can serve as marker lights, clearance lights, indicator lights, or high-output brake/stop lamps depending on wiring and placement.

• Commercial trailers and tractor-trailers — marker and brake functions
• RVs and campers — compact clearance lighting
• Boats and marine trailers — waterproof signaling
• Work vehicles and specialty equipment — durable, sealed lighting

Who is this for? Installers, fleet managers, RV owners, boaters, and DIY vehicle owners who need a compact, durable red LED marker that combines easy flush mounting, separate low/high brightness control, and proven waterproofing will find these Nilight lights a practical choice. They are particularly useful when you want low-level running illumination plus a brighter stop/turn signal without adding separate fixtures. The 10-piece pack covers multiple mounting points or spare replacements for routine maintenance.
