Oyviny 4" Round LED Reverse Lights — 24-LED White Backup Pair, IP65 Waterproof, Surface-Mount

These Oyviny 4" round reverse/back-up lights use 24 high-efficiency LEDs to produce a focused, bright white beam that improves rear visibility for 12V vehicles. Built with a reflective bowl and sealed housing, they offer strong light output with lower current draw and enhanced weather resistance. The pair is designed for surface-mount installation with a rubber grommet to reduce water ingress, making them suitable for trailers, buses, RVs, and trucks where DOT-style brightness and reliable operation are needed.

How bright are these 24-LED backup lights in real use?

The 24 LEDs are arranged with a reflective bowl to concentrate output into a clear white beam, which increases visibility when reversing at night or during poor weather. LEDs light almost instantly and consume less power than incandescent equivalents.

• 24 quality LED diodes for intense white output
• Reflective bowl for tighter, more visible beam
• Lower current draw and reduced heat compared with bulbs

Will they stand up to road moisture and corrosion?

Each light is assembled with a welded lens and housing and sealed with silicone to achieve an IP65 rating, protecting against dust and low-pressure water jets. In addition, the supplied rubber grommet helps keep the mounting point snug and further limits moisture entry.

• Welded lens-to-housing seam with silicone sealing
• IP65-rated protection for dust and splashing water
• Included rubber grommet improves mounting water-resistance

How easy is installation on trailers and vehicles?

These 4" reverse lights are made for surface-mounting without screws; you select an appropriate hole and press the unit into place. They use a standard 3-pin wiring connection (wiring not included), and the required hole dimensions are clearly defined to speed fitment.

• Surface-mount design — no screws required for basic installation
• Hole recommendation: 5.4" diameter, 1.2" depth for proper seating
• Connects to a standard 3-pin light wire (not supplied)
