XtraGlow LED Trailer Tail Light Kit 10-inch Submersible American Flag — Waterproof, Complete 7-Function Set

XtraGlow's submersible 10-inch square LED trailer tail light kit combines American-flag style rear lamps, a 10" third brake light bar, four side markers, a 25ft wiring harness and mounting hardware for a complete 12V trailer lighting solution.

This all-in-one kit is built for trailers up to 80 inches wide and includes everything needed for a full rear lighting setup: two square American-flag LED tail lights with integrated license plate illumination, a 10-inch LED third brake light bar, two red and two amber mini side markers, a 25-foot 4-flat wiring harness, a license plate bracket and mounting hardware. The lights are fully sealed and rated to withstand wet environments, making them a good option for boat trailers, utility trailers, snowmobile haulers and other towing uses where water exposure and rough conditions are expected.

How does this kit improve visibility and safety on trailers?

The kit supplies seven essential lighting functions — stop, turn, tail, side marker, side reflector, rear reflector and license plate light — plus a high-mounted 10" brake light bar for earlier driver recognition. LEDs offer brighter, quicker illumination than incandescent bulbs, improving reaction time from following drivers.

• Two square rear lights with 15 diodes each: stop/turn/tail plus built-in white license LEDs
• 10" third brake light bar with 14 x 2835 LEDs for centralized signaling
• Four mini oval side markers (2 red, 2 amber) for lateral visibility and clearance

Are these lights suitable for water exposure and harsh conditions?

Yes — each lamp is fully sealed in a waterproof housing to protect the internal circuit board from moisture and corrosion. That sealed construction helps the kit survive immersion, rain, snow and road spray common in marine and winter towing environments.

• Fully sealed housings prevent water ingress into LED circuits
• Aluminum-alloy bases provide corrosion resistance and heat dissipation
• Durable sealing and materials rated for outdoor use and submersion

How straightforward is installation and wiring for this complete kit?

The kit includes a 25-foot wiring harness with a standard 4-flat plug plus clear wire-color guidance for each component, so most users can complete the install without specialty tools. Color-coded leads and the included license bracket and mounting hardware keep the process organized.

• 25ft harness with 4-flat plug connects to most towing vehicles
• Color wiring tips: square lights (white ground, brown low, yellow/green high); 10" bar (white ground, black low, red high)
• All mounting hardware and license plate bracket included for immediate installation

What are the LED brightness and component specifics?

The square tail lights use a combination of red and white diodes to deliver stop/turn/tail and license plate illumination, and the 10" bar uses high-density 2835 LEDs for a strong, uniform brake signal. These specs balance visibility with low power draw typical of LED systems.

• Square tail lights: 15 diodes each (12 red + 3 white for license plate)
• 10" third brake light bar: 14 x 2835 LEDs for bright centralized signaling
• Mini markers: compact oval LEDs in red and amber for side visibility

Who is this for? This XtraGlow kit is designed for boat owners, utility trailer users, RV owners and recreational vehicle haulers who need a reliable, waterproof rear lighting package that looks distinctive and installs without specialty parts. It fits trailers up to 80" wide and is especially useful where exposure to water, salt or winter conditions makes a sealed LED solution preferable. Choose this kit if you want a complete, American-flag-styled lighting upgrade with a bundled harness and mounting hardware for fast installation.
