XtraGlow Submersible LED Trailer Tail Light Kit 10-inch American Flag — Waterproof, Aluminum-Alloy

XtraGlow's submersible 10" square LED trailer tail light kit supplies seven required lighting functions in a waterproof American-flag design for trailers up to 80" wide.

This all-in-one 12V lighting package combines two square American-flag tail lights, a 10-inch third brake light bar, four mini side markers, a 25-foot 4-flat wiring harness, a license plate bracket, and mounting hardware—ready to replace or upgrade your trailer lighting. Built with a sealed aluminum-alloy base and high-efficiency LEDs, the kit balances visibility, corrosion resistance, and simple wiring to perform reliably in wet, snowy, or submerged conditions.

How does this kit meet DOT-style lighting needs on trailers?

The XtraGlow kit covers the standard functions most states require for trailer operation, consolidating multiple lights into coordinated units to simplify compliance. Each component plays a role in stop/turn/tail signaling, side marking, and plate illumination so you get legally visible lighting without separate parts.

• Seven combined functions: stop, turn, tail, side marker, side reflector, rear reflector, license plate light.
• Includes a 10" third brake light bar for an elevated, center-mounted brake signal.
• Mini side markers (2 red, 2 amber) for clearance and lateral visibility.
• Built-in license plate illumination on the driver side tail light.

Will these lights survive marine and winter conditions?

Yes—the housings are fully sealed and use aluminum-alloy bases that resist corrosion and water intrusion, making them suitable for boat trailers, snowmobiles, and utility trailers exposed to spray or immersion. The LED electronics are protected inside an IP-style sealed enclosure to reduce failure risk in harsh environments.

• Fully sealed, waterproof construction prevents moisture entry into the circuit board.
• Aluminum-alloy bases resist rust and hold up to salty or wet conditions.
• LEDs generate less heat and last longer than incandescent bulbs in cold climates.
• Designed for submerged use and heavy road spray without compromised performance.

How easy is installation and what wiring should I expect?

The kit arrives with a 25-foot harness and a 4-flat plug to connect to common trailer wiring systems; color-coded leads simplify hook-up for each light’s functions. Clear wiring tips are provided for each component, so installation typically requires only basic tools and standard trailer wire connections.

• Included 25ft wiring harness with 4-flat plug for straightforward connection to tow vehicle.
• Color-coded leads: square tail lights (white ground, brown low, yellow/green high), 10" bar (white ground, black low, red high), side markers (white ground, red positive).
• Mounting hardware and license plate bracket included for complete setup.
• Plug-and-play for most trailers under 80" wide; minimal splicing if adapting to nonstandard systems.

What brightness and LED layout can I expect from each piece?

The square tail lights pack multiple diodes for signal and plate illumination, while the 10" light bar uses compact SMD LEDs to produce a bright, uniform stop/turn/tail output. This combination gives clear, visible cues to other drivers in daytime and nighttime conditions.

• Square tail lights: 15 diodes (12 red + 3 white) including license plate LEDs.
• 10" third brake light bar: 14 x 2835 SMD LEDs for even, high-visibility brake signaling.
• Mini side markers: compact LEDs for clearance indication and reflector functions.
• LED design reduces power draw while improving longevity versus incandescent bulbs.

Who this kit is for: XtraGlow's Submersible Square LED Trailer Tail Light Kit is aimed at trailer owners who need a complete, low-maintenance lighting update—boat and utility trailer operators, snowmobile haulers, and anyone towing trailers up to 80" wide who wants corrosion-resistant, waterproof lighting with an American-flag aesthetic. It’s ideal for users seeking plug-ready wiring, strong visibility from LEDs, and a durable aluminum-alloy build that holds up to wet or salty conditions.
