Partsam 17" Amber LED Light Bar - 40-LED Sealed Turn Signal & Tail Marker, Pack of 2

Partsam's 17" thin amber LED light bar is a sealed, 3-wire combination turn signal and tail/marker lamp designed for durable, bright visibility on trailers, trucks, RVs and specialty vehicles.

This sealed 17.12" amber LED strip (pack of 2) uses 40 Super FLUX LEDs behind an amber lens and chrome bezel to deliver strong, consistent light while resisting road moisture and dust. The low-profile housing measures about 1.58" wide and 0.83" tall, with roughly 16" mounting hole spacing, making it easy to fit where more compact marker or signal lamps are needed. The assembly is DOT-compliant for lighting applications where compliance and reliability matter.

How does this light bar handle both turn-signal and tail/marker roles?

The Partsam light bar is a 3-wire design that separates functions for high and low brightness. Use the high-brightness feed for turn signals and the low-brightness feed for tail or marker lights; you may also wire it with two wires to use a single function only. This flexibility makes the lamp suitable for combination applications without extra modules.

• Three wires: white = ground, red = high-brightness (turn), gray = low-brightness (tail/marker)
• Operates as combined turn-and-tail or single-function if desired
• Plug-and-play wiring style for retrofit or new installations

How bright and durable is the LED strip for on-road use?

The unit employs 40 Super FLUX LEDs that provide a vivid amber output for quick recognition by other drivers. Its sealed construction and chrome bezel protect the LEDs and internal wiring from water and road grime, extending service life in harsh conditions. DOT compliance assures that the light meets standard visibility requirements for many vehicle applications.

• 40 high-power Super FLUX LEDs for strong amber illumination
• Sealed housing resists moisture and dust for outdoor durability
• Chrome bezel for added protection and cleaner mounting appearance
