Partswcgg 4" Round Amber Recessed LED Strobe Lights — 4in Flush-Mount, 24-LED, Steady or Rapid Flash

Partswcgg 4" Round Amber Recessed LED Strobe Lights are compact, 24-LED flush-mount amber strobes designed for 10–30V vehicles, offering selectable solid or rapid-flash signaling in a waterproof, plug-and-play assembly.

These recessed 4-inch amber LED strobe lights from Partswcgg combine a low-profile design with high-visibility LED output. Each lamp houses 24 LEDs in a sealed housing and includes a rubber grommet and three-prong pigtail for simplified installation. The unit supports both steady and quick-flash modes and operates across a broad 10–30V range, making it compatible with many truck, trailer, and utility vehicle systems.

How do I wire these lights for steady and strobe modes?

Wiring is intentionally simple with three color-coded leads. White is ground; brown provides a steady amber turn-signal output; red activates the quick-flash strobe function. Use the included 3-prong pigtail for a direct connection to your vehicle harness, or splice into your wiring following standard safety practices.

• White = ground
• Brown = steady amber signal
• Red = rapid-flash strobe
• Compatible with 10–30V DC systems

Will these lights fit my trailer or truck — what are the installation dimensions?

The lamp body has a 4-inch inner diameter with a grommet ring of approximately 5.3 inches and 1-inch overall thickness. For a clean flush-mount, plan a hole around 4.6 inches in diameter; the included rubber grommet helps ensure a snug, sealed fit. The compact depth is intended for most trailer walls and vehicle panels where recessed mounting is preferred.

• Inner diameter: 4 inches
• Grommet ring outer ~5.3 inches
• Recommended hole: ~4.6 inches
• Body thickness: ~1 inch for recessed mounting

Are these LED strobes durable and weatherproof for outdoor use?

Partswcgg engineered these strobes to withstand harsh outdoor conditions. The units are sonically sealed and rated IP67, meaning they are dust-resistant and submersible for short periods, and the rugged construction resists vibration and moisture commonly encountered on trailers and utility vehicles. LEDs draw less current than incandescent equivalents while delivering brighter, longer-lasting illumination.

• IP67-rated for dust and temporary submersion
• Sonic-sealed housing for vibration resistance
• 24 LEDs for brighter, lower-current output
• Works in varied weather and temperatures

What vehicles and applications are these lights best suited for?

These 4-inch amber LED strobes are designed for a wide array of 10–30V vehicles and trailers. Common uses include semi-trailers, utility trucks, service vans, boats, parade floats, horse trailers, and off-road utility vehicles. Because they offer both steady and strobe outputs, they serve well for marker, turn, and attention signaling across commercial and recreational setups.

• Semi trucks, trailers, and utility trailers
• Service vans, buses, and pickup trucks
• Boat trailers, parade floats, and horse trailers
• UTVs, UTEs, and other 10–30V equipment

Who this is for: Installers, fleet managers, and owners of trailers or utility vehicles who need a compact, weatherproof amber signaling light with flexible flash modes will find these Partswcgg 4" recessed LEDs a practical choice. They suit anyone seeking easy plug-and-play installation, brighter LED output than incandescent bulbs, and robust sealing for outdoor environments. If you require visible amber signaling with low power draw and straightforward wiring, these strobes are built for that purpose.
