Partswcgg 4-inch Amber Recessed LED Strobe Lights (4‑Pack) — 24-LED, IP67, Plug-and-Play Flush Mount

Bright, weatherproof 4" amber recessed LED strobe lights by Partswcgg — a four-piece kit with 24 LEDs per lamp, plug-and-play pigtails, and a flush-mount grommet for trailer and vehicle use.

These Partswcgg 4-inch round amber recessed strobe lights are built for vehicle signaling and attention-grabbing applications where a compact, reliable lamp is required. Each sealed unit houses 24 high-efficiency LEDs and connects using a three-prong pigtail, allowing simple installation on trailers, utility vehicles, trucks, and more. Rated for 10–30V DC and IP67 sealed construction, they tolerate wet conditions and road vibration while delivering a solid or rapid flash depending on wiring.

How do I install these recessed amber strobe lights?

Installation is straightforward: cut a mounting hole near the specified diameter, press the grommet into the opening, and route the pigtail wires to your vehicle's circuit. The included black rubber grommet creates a flush fit and helps keep the lens sealed against moisture and dust.

• Drill a hole approximately 4.6" diameter for the 4" inner lamp and 5.3" grommet ring.
• Use the three-prong pigtail: white = ground, brown = steady run/turn, red = rapid flash strobe.
• Ensure power source is 10–30V DC and secure wiring with connectors or heat-shrink.
• Push lamp into grommet until flush; test functions before finalizing.

What lighting modes and wiring options are available?

Each lamp supports two distinct outputs depending on which wire you energize: a steady amber light for turn/run function and a quick strobe flash for attention or hazard signaling. This gives installers flexibility to use one lamp for multiple roles without extra hardware.

• Brown wire supplies continuous amber output suitable for turn signals or marker lights.
• Red wire activates the fast strobe flash for warning or emergency-style signaling.
• White wire is the common ground to complete the circuit.
• Works across a broad 10–30V DC range, compatible with most vehicle systems.

Are these lights durable enough for outdoor and marine use?

Partswcgg built these lights to be rugged and sealed for harsh environments. The housings are sonically sealed and rated IP67, which means temporary submersion and heavy exposure to rain or road spray won’t compromise function.

• IP67-rated enclosure keeps out dust and protects against immersion up to 1 meter briefly.
• Sonic sealing and rubber grommet reduce water ingress around the mounting point.
• LEDs use less current than incandescent bulbs and resist vibration-related failure.
• Suitable for trailers, boats, utility vehicles, and exposed exterior mounts.

What are the physical dimensions and compatible vehicles?

Each lamp is designed as a 4-inch round unit with an inner lens diameter of four inches and a grommet ring near 5.3 inches, plus roughly 1" thickness. They fit a wide array of 10–30V DC vehicles and trailers where compact recessed lighting is preferred.

• Inner lamp diameter: 4"; recommended hole size for installation: ~4.6".
• Grommet ring outside diameter: approximately 5.3"; lamp depth about 1".
• Compatible with semi-trailers, service trucks, buses, RVs, UTVs, boats, horse trailers, and more.
• Each unit contains 24 LEDs for high visibility while drawing low current.

Who is this for? Owners and operators who need compact, durable amber signaling lights for trailers, trucks, utility vehicles, and marine trailers will find this Partswcgg 4" recessed LED kit ideal. It’s aimed at installers and DIYers who want a simple plug-and-play wiring option, long-lasting LED performance, and IP67 sealing for wet or dusty conditions. If you need reliable turn, run, and strobe capability in a low-profile, flush-mounted package, this four-piece kit suits fleet maintenance, seasonal float/ parade lighting, and aftermarket trailer upgrades.
