Ronybuy 4" Round LED Trailer Tail Lights 10-Pack — 24-LED Sealed Red, Waterproof IP65, 3-Prong Plug

These are Ronybuy 4-inch round LED trailer tail lights (10-pack) with 24 LEDs each — sealed, waterproof, and wired for stop/turn/brake and tail functions for 12V vehicles.

If you need a complete lighting replacement or upgrade for trailers, trucks, RVs, or specialty equipment, this 10-piece set supplies matched round red tail lights with rubber grommets and 3-prong plugs for plug-and-play installation. Each lamp contains 24 LEDs arranged for bright high/low output, a molded 3-prong pigtail, and an IP65-rated sealed body to resist weather and road spray. The package includes everything to mount and wire ten lights so you can outfit multiple points or keep spares on hand.

How bright and versatile are these 4" LED tail lights?

Each lamp uses 24 LED chips and supports two brightness levels — high for stop/turn/brake and low for running/tail light. The LEDs are arranged to deliver consistent visibility from common viewing angles while minimizing heat build-up for longer life. They are suitable where distinct brake, turn, and running signals are required.

• 24 LED chips per light for improved luminosity and thermal performance
• Two brightness modes: high (stop/turn/brake) and low (tail/running)
• Clear, even illumination designed for 12V vehicle electrical systems

Will these lights hold up in bad weather and road conditions?

The lights feature an LED water-tight sealed design, premium rubber grommet rings, and molded 3-prong plugs to resist dust and moisture, earning an IP65 rating for splash and spray protection. They’re built for roadside exposure but should not be submerged or exposed to concentrated saltwater. Proper installation and gasket seating ensure the best moisture resistance.

• IP65 water-resistant construction for rain and road spray
• Rubber grommets included to seal mounting holes and prevent leaks
• Molded 3-prong pigtail reduces connector corrosion and ensures reliable contact

How do I install and wire these flush-mount trailer lights?

Installation is straightforward: each light is a sealed flush-mount unit sized to fit typical 4" cutouts and includes a 3-prong plug for simple wiring. Wire color coding is provided for quick hookups, and the package includes the rubber grommets for a clean, secure fit in the mounting hole.

• White wire: ground (negative)
• Red + white: high brightness for stop/turn/brake function
• Black + white: low brightness for tail/running light function
• Includes 10 rubber grommets and 10 molded 3-prong plugs — plug-and-play ready

What are the dimensions and compatibility details I should check first?

The outer grommet diameter is 5.3", the inner light diameter is about 4.1", and the light thickness is approximately 1" — measure your mounting hole before purchasing. The 3-prong pigtail is about 18 cm (7.1") long, and these lights are intended for standard 12V DC systems found on trailers, trucks, RVs, and many utility vehicles.

• Outer grommet diameter: 5.3"; inner lens diameter: 4.1"; thickness: 1"
• Pigtail length: ~18 cm (7.1") for easy routing
• Designed for 12V DC systems—compatible with most trailers, trucks, and RVs

Who is this for? Installers, fleet owners, RV enthusiasts, and trailer owners who want a reliable, all-in-one lighting solution will appreciate this Ronybuy 10-piece set. It’s ideal for outfitting multiple lights at once, keeping matched spares, or completing larger trailer projects where consistent appearance and plug-and-play wiring reduce installation time. If you’re replacing worn lenses, upgrading incandescent bulbs, or preparing vehicles for safer road presence, this set gives a matched, weather-resistant option — just confirm your cutout dimensions and 12V compatibility before buying.
