Partsam 17" Amber LED Light Bar - Pack of 2 Slim 40-LED Sealed Turn Signal & Tail Marker with Chrome Bezel

Partsam 17-inch thin amber LED light bar is a sealed, DOT-compliant 3-wire turn signal and taillight assembly with 40 high-power LEDs, chrome bezel, and mounting hardware — sold as a pack of two.

This slim LED strip is built for visibility and flexible installation on trailers, trucks, RVs and many work vehicles. The sealed housing and chrome bezel present a low-profile, corrosion-resistant finish that resists road grime and weather. With a 3-wire design the lamp functions as a bright turn signal and a lower-intensity running/tail light so you can wire it to fit your vehicle's lighting circuit needs.

How does this light bar handle turn signal and tail light roles?

The Partsam 17" amber bar uses a 3-wire system that separates signal brightness from the low-run/taillight mode, allowing both functions to operate from a single unit. Use all three wires for combined signal and tail light behavior or two wires if you only need one function. The Super FLUX LEDs provide a strong, visible flash for signaling while a reduced-intensity circuit keeps the lamp useful as a running or marker light.

• 3-wire: white ground, red high-brightness (turn), gray low-brightness (tail/marker).
• 40 Super FLUX LEDs deliver clear, attention-grabbing signal output.
• Can be wired as turn + tail, turn-only, or tail-only depending on needs.

What are the size and build details I should know before mounting?

This bar measures approximately 17.12" long by 1.58" wide and 0.83" high, with a hole-to-hole mounting spread around 16" for straightforward replacement or new installations. The sealed amber lens and chrome bezel offer corrosion resistance and a neat factory-style appearance. Screws are included so you can mount immediately; expect a low-profile fit across fenders, trailer boards, or bumper faces.

• Overall dimensions 17.12" L x 1.58" W x 0.83" H; hole spacing ~16".
• Sealed housing keeps moisture and dirt out for longer life.
• Chrome bezel provides a clean visual match with many vehicles.

Which vehicles and applications are these lights best suited for?

These bars are designed as universal marker, clearance, turn signal or identification lights for trailers and commercial vehicles. They are appropriate for semi trailers, pickup trucks, horse trailers, RVs, service trucks, dump trucks, floats and many specialty vehicles. Use them where a slim, visible amber marker is needed without major modification.

• Common fitments: semi-trailers, flatbeds, service trucks, campers, horse trailers.
• Ideal for retrofit or new installations requiring DOT-compliant amber marker lights.
• Pack of two gives left and right coverage or spare replacement.

How should I wire and maintain the Partsam 17" LED bar?

Connect the white wire to chassis ground, red to the turn signal circuit for high-brightness strobes, and gray to the tail/running circuit for low-brightness operation. If you prefer single-function use, cap off the unused wire. Periodic cleaning of the bezel and inspection of the wiring will keep the sealed unit performing well; if condensation appears, check mounting seals and vehicle grounds.

• White = ground, Red = turn/high brightness, Gray = tail/low brightness.
• Cap unused wire for one-function setups; tighten included screws for secure mounting.
• Wipe lens clean and inspect seals to maintain visibility and longevity.
