Partsam 17" Amber LED Turn Signal Light Bar 2-Pack — 40-LED Sealed Chrome Bezel, Low-Profile

Partsam's 17" thin amber LED turn signal light bar is a sealed, 40-LED amber marker that combines turn-signal and tail/parking light functions in a slim, DOT-compliant chrome-bezeled package (pack of 2).

These 17.12" amber LED light bars are designed for utility vehicles, trailers, RVs and trucks that need a bright, low-profile signaling solution. Each bar uses 40 Super FLUX LEDs in a sealed housing with a chrome bezel and amber lens, offering both high-brightness and low-brightness modes through a three-wire hookup. The compact 1.58" width and 0.83" height make these bars easy to mount in tight spaces while meeting identification, marker and turn-signal needs.

How does this light bar handle both turn signal and tail/parking light duties?

The Partsam 17" light bar uses a 3-wire design to provide dual-function operation. One wire delivers a high-brightness signal for turn indicators, while a low-brightness feed provides running or parking light illumination. You can also choose to wire only two leads and leave the third unused if you want single-function use.

• Three-wire setup: red = high/turn, gray = low/tail, white = ground
• High mode for turn signals; low mode for tail/parking lights
• Simple to convert to single-function by ignoring one wire
• Sealed housing prevents moisture intrusion at wiring points

What are the key specs and physical dimensions I should know?

Each bar measures 17.12" long, 1.58" wide and 0.83" tall, with an approximate hole-to-hole mounting distance of 16". The low-profile form factor fits neatly beneath trim, on trailers, or on truck rear panels without protruding. Built from a sealed lens and chrome bezel, the assembly is engineered to be weather-resistant for exterior use.

• Overall dimensions: 17.12" L x 1.58" W x 0.83" H
• Approx. 16" between mounting holes for easy retrofit
• 40 Super FLUX LEDs for bright, consistent output
• Comes with mounting screws for straightforward installation

How durable and weatherproof are these LED bars for outdoor use?

The light bars are sealed to keep out water and dust, and the chrome bezel helps protect the lens edge from impact and road debris. Because the LEDs run cool and are solid-state, the bars resist vibration and thermal cycling better than incandescent lamps. They are intended for exterior vehicle use across many applications where moisture and road grime are common.

• Sealed lens and housing to resist water and dust ingress
• Chrome bezel adds edge protection against impacts
• Solid-state LEDs withstand vibration and temperature changes
• Suitable for regular outdoor exposure on vehicles

How easy is installation and what wiring tips help avoid mistakes?

Installation is straightforward: secure the bar with the included screws and connect the three wires to your vehicle harness. Use the white wire as ground, red for high/turn signal output, and gray for low/tail/parking lights. If you only require one function, simply connect two wires and cap the unused lead.

• Includes mounting screws for quick attachment
• White = ground, red = high/turn, gray = low/tail
• Can be used as combined or single-function light with simple wiring
• Universal fit for trucks, trailers, RVs and more

Who is this for: These Partsam 17" amber LED light bars are made for vehicle owners and fleet managers who need a slim, bright signaling solution for trucks, trailers, RVs, buses and specialty vehicles. They suit anyone replacing worn marker lamps, upgrading to LEDs for better visibility and durability, or adding turn-signal capability in low-clearance mounting locations. Ideal when you want DOT-style amber signaling in a compact, sealed assembly that’s easy to install and versatile across vehicle types.
