Partsam 17" Clear Lens Red LED Tail Light Bar — 40-LED DOT-Approved Sealed Waterproof

The Partsam 17" Clear Lens Red LED Tail Light Bar is a low-profile, DOT-approved 40-LED identification and brake/turn/tail lamp designed for trailers and trucks that need a bright, sealed center or side mount light.

This slim 17-inch light bar combines a clear lens with red LEDs to provide Stop/Turn/Tail functions and can be mounted horizontally, vertically, or at an angle when space is limited. Built with 40 high-output NICHIA Super FLUX LEDs and a sonically sealed housing, the bar delivers strong visibility while resisting water intrusion — making it suitable for trailers, boat trailers, utility trucks and other 12V vehicle applications that require DOT-compliant lighting.

How bright and visible is this LED light bar?

The Partsam bar uses 40 high-power NICHIA Super FLUX LEDs that produce approximately 460 lumens of output, giving a noticeable increase in brightness over standard incandescent markers. The clear lens with red LED emitters provides crisp signaling that's easily seen in daylight and at night.

• 40 NICHIA Super FLUX LEDs for high lumen output
• Approximately 460 lumens total brightness
• Clear lens emphasizing the red LED output for visibility
• Effective for Stop, Turn, Tail and center third brake use

Can this light bar handle wet or submerged conditions?

Yes — the fixture is sonically sealed so the lens and housing form a single waterproof unit that prevents water from reaching the LEDs or circuit board. That construction makes it a practical choice for boat trailers and other applications where the light may be exposed to splash or temporary submersion.

• Sonic seal bonds lens to housing for a watertight enclosure
• Sealed electronics reduce corrosion and failure risk
• Suitable for trailers that encounter water or heavy spray
• DOT-approved design meets typical legal and safety requirements

How do I wire and mount the light bar?

Wiring is straightforward: white is ground, red provides the high-brightness (stop/turn), and gray supplies the low-brightness tail function. The low-profile bar is designed for flexible mounting positions — horizontal, vertical, or at an angle — which helps when mounting space is limited.

• Three-wire configuration: white = ground, red = high, gray = low
• Slim 17" footprint fits tight mounting locations
• Can be used as center third brake light or side marker/ID bar
• Surface-mount design for quick installation on trailers and trucks

Which vehicles and applications is this compatible with?

The Partsam 17" LED bar is a universal 12V light designed for use on a wide range of vehicles including heavy-duty trucks, semi trailers, pickup trucks, cargo and utility trailers, horse trailers, and boat trailers. Its DOT approval and multi-function capability make it suitable for both identification and signaling roles on vehicles wider than 80 inches.

• Universal 12V compatibility for most trucks and trailers
• Works as stop, turn, tail, marker, identification or 3rd brake light
• Designed for heavy-duty and recreational trailer use
• Compact profile for use on cramped or custom installations

Who is this for: The Partsam 17" Red LED Tail Light Bar is ideal for fleet owners, trailer builders, and DIY vehicle owners who need a bright, waterproof, DOT-rated light that fits limited spaces and performs multiple signaling roles. Choose this light when you want a durable, sealed LED solution for trailers, boat trailers, trucks, or any 12V vehicle requiring improved visibility and a low-profile mounting option.
