EXERAUO 17-inch 12-LED Red Trailer Light Bar — Low-Profile Waterproof Brake & Tail Light, Dual-Brightness

EXERAUO's 17-inch 12-LED red trailer light bar is a low-profile, waterproof multi-function brake and tail light designed to increase visibility on trailers and trucks.

This lamp bar combines a compact aluminum housing with 12 high-output LEDs to serve as marker, tail, stop, turn signal and parking lights in one sealed assembly. Built with a sonically welded polycarbonate lens and straightforward three-wire hookup, the unit installs horizontally, vertically, or at an angle and is suitable for most 12V heavy-duty vehicles and trailers.

How will this light bar improve my trailer's visibility?

The EXERAUO light bar uses bright LEDs and a sealed lens to deliver clearer signaling and side marker illumination in rain, fog, or night driving. LEDs react quickly for brake and turn signals, and the low/bright modes help meet different regulatory or towing needs.

• 12 high-intensity LEDs for sharp, noticeable light output
• Dual-brightness design: low for markers/parking, high for braking
• Weatherproof polycarbonate lens prevents moisture intrusion
• DOT-style fit for common trailer applications

What are the installation and wiring steps?

Installation is simple: position the 17-inch bar, secure both ends with the included screws, and connect the three wires to the vehicle harness. The white wire is ground, black is low/intensity, and red is high/intensity (brake); no special tools or housings are required for basic mounting.

• Includes 2 light bars and 4 mounting screws per package
• Hole-to-hole mounting distance: 16 inches for easy alignment
• Three-wire hookup: white = negative, black = low, red = high
• Can be mounted horizontally, vertically, or angled

Is this light bar durable enough for heavy-duty and marine use?

The housing and sonically welded lens are engineered to resist water and dust, making the light suitable for outdoor, off-road, and marine trailer conditions. The solid-state LED design also withstands vibration and frequent use better than filament bulbs.

• Sealed assembly prevents moisture and corrosion
• Polycarbonate lens resists impact and UV degradation
• Aluminum-based housing reduces weight and improves heat dissipation
• Designed for 12V systems used in trucks, trailers, RVs and boats

Which vehicles and trailers are compatible with this 17-inch light bar?

Because the bar uses standard 12V wiring and common mounting spacing, it fits a wide array of tow and work vehicles. It's a practical choice for owners who need an additional top-of-door brake light, center-mounted tail bar, or side marker replacement on larger trailers.

• Fits cargo, travel, boat, horse, and semi trailers
• Works with RVs, campers, work trucks, and utility trailers
• Compatible with UTVs, ATVs, and golf carts on 12V systems
• Useful as a supplemental brake/marker bar for increased visibility

Who is this for: The EXERAUO 17-inch 12-LED red trailer light bar is aimed at trailer owners, fleet managers, and recreational vehicle users who want an affordable, robust light upgrade to boost rear visibility and signaling. If you need a waterproof, easy-to-wire LED bar that mounts in multiple orientations and fits most 12V heavy-duty applications, this product provides a straightforward, durable solution without complex installation.
