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

Oyviny 4-inch round reverse lights are a pair of 24-LED, surface-mount backup lamps designed to deliver focused, high-visibility white light for trailers, trucks, RVs and buses while resisting moisture with an IP65 seal.

These compact 4" LED reverse/back-up lights combine a reflective bowl, efficient diodes and a rubber grommeted housing to produce brighter illumination with lower current draw than incandescent bulbs. Built for 12V systems, they’re intended for surface-mount installation on trailers, campers, trucks, buses and similar vehicles where durable, easy-to-fit reverse lighting is needed.

How bright are these 24 LEDs and what makes them more visible?

The lights use 24 quality LED diodes and a reflective bowl that concentrates the beam into a clear, white backup pattern. LEDs light faster and draw less current than incandescent lamps, so they produce intense output without excessive heat.

• 24 high-efficiency LED diodes for intense white illumination
• Reflective bowl concentrates light for longer, clearer visibility
• Faster light-up time than incandescent bulbs
• Lower power consumption reduces stress on 12V circuits

Are these lights waterproof and durable for outdoor use?

Yes — the lens and housing are welded and sealed with silicone to achieve an IP65 rating, keeping out moisture and most dust. Each lamp also includes a tight-fitting rubber grommet to improve water resistance where wiring passes through the mounting hole.

• IP65-rated sealed lens and housing for rain and splash protection
• Silicone weld prevents water ingress and corrosion at seams
• Rubber grommet seals the mounting aperture around wiring
• Robust construction suited to road vibrations and outdoor conditions

How simple is installation and what wiring does it require?

Installation is designed to be straightforward: these are surface-mount units that do not require screws for attachment, only a correctly sized hole and a standard 3-pin light wire. The listed hole dimension and depth help you prepare the mounting location so the lens and grommet seat properly.

• Surface-mount — no screws required for the light body
• Recommended hole size: 5.4" diameter with 1.2" depth
• Works with standard 3-pin 12V light wiring (wire harness not included)
• Plug-and-play wiring reduces installation time on trailers and RVs

What vehicles are these reverse lights suitable for?

These 4" white LED reverse lights are compatible with most 12V vehicles needing backup illumination, including trailers, pickup trucks, RVs, buses and light-duty commercial vehicles. They’re intended as reverse or backup lamps and complement existing tail lighting systems.

• Ideal for trailers, campers, motorhomes, and semi trailers
• Fits buses, vans and pickup trucks using 12V electrical systems
• Commonly used as reverse/back-up or auxiliary illumination
• Sold as a pair to outfit both sides or replace two existing lights

Who is this for? The Oyviny 24-LED 4" reverse light pair is aimed at vehicle owners and fleet managers who need a compact, energy-efficient backup lamp that’s bright, weather-resistant and quick to install. It’s suitable for DIY trailer maintenance, RV upgrades, commercial fleets and anyone replacing worn incandescent reverse lamps with a more efficient LED solution. Note: the lights are splash-resistant but not designed for continuous underwater use; ensure proper mounting and wiring for best long-term performance.
