Nilight 3/4" Round LED Marker & Turn Signal Light — 3-Wire Dual-Brightness, IP68 Sealed Flush-Mount

Nilight 3/4" round bullet lights are compact LED markers that function as both low-level clearance lights and brighter turn signals using a three-wire hookup for dual-brightness control.

These miniature lights combine focused 3030 SMD LEDs with an upgraded three-conductor connection and a flush-mount grommet so you can install marker, indicator, or turn-signal functionality in tight spots on trailers, trucks, RVs and specialty vehicles. The housing is fully sealed and potted to protect electronics from moisture and road debris, while the two-stage brightness lets one fixture serve two roles depending on your wiring.

How do these lights deliver both marker and turn-signal functions?

The Nilight units use three wires: ground, a low-brightness feed and a high-brightness feed. You can wire the low line to a running/clearance circuit and the high line to a turn-signal or hazard circuit, letting one lamp perform two duties without changing hardware.

• Three wires: white = ground, black = low brightness, red = high brightness
• Low mode for marker/clearance illumination; high mode for flashing turn signals
• Compact 3/4" diameter fits small mounting locations

Are these lights rugged enough for outdoor and marine use?

Yes — each lamp is fully sealed and the electronic board is encapsulated with hard potting material to keep water and contaminants out. The design meets IP68-level protection, so they withstand immersion and harsh weather when installed correctly.

• Potted circuit board and sealed housing resist moisture and vibration
• Durable rubber grommet provides a snug, flush fit to prevent leaks
• Constructed for use on trailers, trucks, RVs and boats

What does installation require and how do I mount them flush?

Installation is straightforward: drill a 0.78" round hole, push the rubber grommet into the opening, then press the light into the grommet until it seats flush. Connect the three wires to the appropriate circuits and secure wiring with proper connectors and heat-shrink for a weatherproof result.

• Drill a 0.78" hole for the supplied grommet
• Insert grommet, press lamp into place and wire white/black/red accordingly
• Use 4mm-compatible connectors for the upgraded metal terminals

What vehicles and applications are these best suited for?

These lights are ideal wherever compact, multi-function lighting helps save space and wiring complexity. Typical uses include side marker/clearance lights on trailers, auxiliary turn indicators on trucks, accent markers on RVs and waterproof signal lighting for small boats and specialty equipment.

• 12V systems: trucks, trailers, RVs, campers, buses and tractors
• Marine and outdoor equipment that needs IP68-rated illumination
• Places where a single lamp needs both running and signaling roles

Who is this for: Installers, fleet operators and DIY vehicle owners who need compact, weatherproof marker or signaling lights that save space but still deliver bright, visible amber output. If you want a small lamp that can serve as both a low-level marker and a high-visibility turn indicator with simple three-wire wiring, the Nilight 3/4" round bullet lights are designed for that use.
