Nilight LED Trailer Light Kit — Oval Taillights, Round Side Markers & 9-LED ID Bar, Sealed Weatherproof 12V

Nilight's LED Trailer Light Kit combines oval taillights, round side markers and a 9-LED ID bar to provide bright, sealed lighting for trailers, trucks and specialty vehicles. This kit supplies a complete set of exterior lights designed for towing and commercial trailers: two 6-inch oval taillights, four 2-inch round side markers (two red, two amber), and a low-profile 9-LED ID bar with mounting screws. The components use modern SMD LED chips for long life and efficient output, plus sealed housings intended to resist water and vibration on the road.

How bright and durable are these LEDs for highway use?

The lights use a mix of 3030 and 2835 SMD LED chips chosen for consistent lumen output and extended runtime under vibration and temperature changes. Expect strong visibility for brake, tail, turn and marker functions without rapid dimming over time.

• High-quality 3030 and 2835 SMD LEDs for reliable brightness
• Designed to maintain light output under road vibration
• Energy-efficient operation lowers electrical load on your vehicle

What makes installation straightforward for DIY or fleet shops?

The kit is prepared for common trailer wiring setups and includes the screws needed for the ID bar. Oval taillights and round markers mount with grommets and screws, and the wiring uses standard 2- and 3-prong plug connections to match most 12V trailer harnesses.

• Includes self-tapping screws for the 9-LED ID bar
• Uses 2-prong and 3-prong plug connections for quick hookup
• Grommet-style mounting for straightforward panel insertion

Are these lights weatherproof and suitable for marine or open-bed use?

The assemblies are ultrasonically sealed where lens meets housing to minimize moisture intrusion and help guard the LEDs from weather exposure. They are intended for exterior use across rain, splashes, and typical road grime, though surface corrosion prevention depends on mounting location and maintenance.

• Ultrasonic bonding creates a tight lens-to-housing seal
• Water-resistant design for use in rain and road spray
• Suitable for trailers, trucks, boats with appropriate wiring and mounting

What connectors and functions will these lights support on my vehicle?

The kit supports standard 12V DC systems and operates as running/tail, brake, and turn signal lights plus side markers. The included plugs are compatible with common trailer harnesses, making the set a practical replacement or upgrade for many towing applications.

• Designed for 12V DC vehicle electrical systems
• Functions: running/tail, stop/brake, turn signals, and marker lights
• Plug-and-play style connectors reduce wiring complexity

Who is this for? This Nilight kit is aimed at owners and operators who need a dependable, visible lighting solution for trailers, service trucks, horse trailers, RVs and specialty equipment. It's a convenient option for DIY installers and fleet maintenance teams who want bright, sealed LEDs and standard connectors to replace worn incandescent lights or upgrade visibility on the road.
