Nilight 6-Inch LED Trailer Tail Lights 4-Pack — Red Oval Brake/Turn Running Lights, Weatherproof ABS

Nilight 6-inch LED trailer tail lights (4-pack) are compact, high-brightness red LED lamps that combine brake, turn and running light functions for safer towing.

These oval 6" lamps use 10 high-output 3030 LED chips per light and a durable ABS housing with a PC lens, delivering a bright red signal for braking and turning plus a lower-intensity taillight beam. Designed for 12V vehicle systems, they mount with included self-tapping screws and are sealed against dust, water and vibration for reliable exterior use.

How bright are these lights and will they be visible in daylight?

The Nilight LEDs use high-efficiency 3030 chips to provide a strong red output for brake and turn signals while keeping running light output lower for contrast. The high-brightness mode activates for brake or turn functions so the lamp is noticeable in daylight and poor weather.

• 10 × 3030 LED chips per lamp for powerful red output
• Distinct high-brightness brake/turn mode and low-brightness taillight mode
• Designed to exceed visibility of standard halogen bulbs

Are these lights weatherproof and rugged enough for trailer use?

Yes — the lamps are molded from impact-resistant ABS with a polycarbonate lens, and ultrasonic welding creates a sealed enclosure that resists water, dust and shock. That construction helps keep the electronics intact when exposed to road spray, vibration and changing temperatures.

• ABS housing and PC lens for impact resistance
• Ultrasonic weld sealing prevents water and dust ingress
• Engineered for vibration-prone towing environments

How easy is installation and what wiring does it require?

Installation is straightforward but hard-wired rather than plug-and-play: each light includes three wires (ground, high-brightness brake/turn, and low-brightness taillight) and 16 self-tapping screws for mounting. You’ll need basic tools and a means to splice into your vehicle’s 12V lighting circuits.

• White = ground, Red = brake/turn (high brightness), Black = taillight (low brightness)
• Includes 16 self-tapping screws for metal mounting
• Requires hard-wiring; not a pre-terminated plug harness

What vehicles and applications are these lights suited for?

These 6" oval lamps are versatile across many 12V platforms — from small trailers and ATVs to large truck and agricultural rigs. They function as tail, brake, turn, clearance or side marker lights where a compact, bright oval fixture is needed.

• Ideal for trailers, RVs, pickup trucks, horse trailers and boat trailers
• Also suitable for dump trucks, semi-trailers, tractors and buses
• Good for retrofit upgrades or replacing worn/inefficient lamps

Who is this for: Installers, fleet operators and DIY trailer owners who need a dependable, high-visibility lighting upgrade. If you maintain trailers, tow frequently, or want a long-lasting alternative to incandescent tail lamps, this 4-pack offers a sealed, high-brightness solution compatible with standard 12V systems. Note: wiring requires basic electrical work and it’s not a plug-and-play harness.
