Nilight 6" Oval LED Tail & Backup Trailer Light Kit — 4-Pack Grommet Mount, IP65 Waterproof, 3-Prong Plug

Nilight 6" Oval LED Tail & Backup Trailer Light Kit is a four-piece grommet-mount set that combines bright stop/turn LEDs with white backup illumination in a weatherproof housing for trucks, trailers, and specialty vehicles.

This 4-pack from Nilight brings a compact, oval LED combination light engineered for visibility and durability. Each lamp integrates red LEDs for tail/stop/turn signaling plus white LEDs for reverse, all sealed in a silicone-protected lens with an IP65 rating. The kit includes grommets for surface mounting and a three-prong watertight plug to simplify wiring, making it a practical upgrade or replacement for many 12V vehicle lighting circuits.

How bright are these Nilight oval lights and what functions do they perform?

Each lamp contains 10 high-quality SMD LEDs arranged to deliver distinct brightness levels for different functions: full intensity for stop/turn and backup, and lower intensity for tail/marker lighting. This design improves rear visibility at night and during braking while preserving a clear reverse light when backing up.

• 10 SMD LEDs per unit for strong, consistent output
• Red LEDs for tail, stop, and turn signals
• White LEDs dedicated to reverse illumination
• Separate brightness levels for tail versus stop/reverse

Is installation difficult and what hardware is included?

Installation is straightforward: the lights use grommet surface mounts and include upgraded grommets plus a three-prong watertight plug with attached wire. You surface-mount each grommet, push the oval light into place, and connect the three wires to your vehicle’s 12V wiring system—matching ground, tail/stop/turn, and reverse wires.

• Grommets included for secure surface mounting
• 3-prong watertight plug reduces exposure to moisture
• Hole footprint: approximately 6.6" x 2.5" x 1.75" for planning
• Quick wire connections—no complex adapters required

Will these lights stay connected and resist vibration or weather?

Nilight designed the lights with “ears” on each side and upgraded notches in the grommets to lock the lamp firmly in place, while the 3-prong plug has a tighter fit to resist vibration. A silicone seal and IP65 rating provide protection against water ingress and most road-weather conditions, supporting reliable performance over time.

• Side “ears” and grommet notches for shakeproof mounting
• Tighter 3-prong plug fit prevents loose wiring connections
• Silicone-sealed lens for added moisture protection
• IP65 waterproof rating for rain and spray protection

What vehicles and systems are these lights compatible with?

The Nilight oval light kit operates on standard 12V DC electrical systems and suits many rear lighting roles including tail, turn, stop, and reverse on trailers, trucks, tractors, and specialty vehicles. Verify the grommet hole size and mounting depth on your vehicle to ensure a proper fit before purchasing.

• Works with 12V DC systems on trucks and trailers
• Suitable for horse trailers, travel trailers, dump trucks, semi-trailers
• Universal signal functions: tail, stop, turn, reverse
• Measure mounting hole to confirm fitment

Who is this for: This Nilight 6" Oval LED 4-pack suits vehicle owners, fleet operators, and trailer enthusiasts who need reliable combination lights that are bright, weather-resistant, and easy to install. It’s a practical choice for anyone replacing worn lights or upgrading to LED signaling and backup illumination on 12V trailers, work trucks, or specialty equipment.
