Partsam 12" Amber LED Light Bar — Slim 15-LED 2835 SMD, Dual-Brightness Chrome Bezel, Sealed Surface-Mount

Partsam's 12-inch amber LED light bar is a slim, sealed, dual-brightness identification and turn/marker light designed to add high-visibility signaling and a polished chrome look to trailers, trucks, and RVs. This low-profile LED bar combines a bright amber lens, chrome bezel styling, and a watertight housing so you can mount it where space is limited without sacrificing durability. Powered by fifteen high-efficiency 2835 SMD emitters, the bar delivers roughly 460 lumens and supports two output levels for use as an identification, clearance, or turn/emergency signal. It runs on 9–16 volts and is built for universal fitment on a wide range of commercial and recreational vehicles.

How bright and visible is this 12" amber LED light bar?

The Partsam bar uses 15 high-power 2835 SMD LEDs producing an estimated 460 lumens, which offers noticeably greater brightness than traditional incandescent marker lights. Dual-brightness operation lets you choose a lower marker output or a higher flash/output for signaling, improving visibility in daylight and at night.

• 15 x 2835 SMD chips for concentrated amber illumination
• Approx. 460 lumen total output
• Two brightness levels (low for marker, high for signal/emergency)
• Clear lens with chrome bezel enhances perceived brightness and style

Where and how can I mount this light bar on my vehicle?

The bar is thin and low-profile (11-13/16" L × 9/16" W × 9/16" H), allowing horizontal, vertical, or angled surface mounting wherever clearance is tight. Mounting hole spacing is about 11 7/16", so it fits common trailer and truck mounting patterns; surface screws secure the unit while the sealed body resists road grime.

• Dimensions: 11-13/16" long, 9/16" wide and high
• Mounting holes spacing: ~11 7/16" for easy fitment
• Surface-mount installation — horizontal, vertical, or angled placement
• Low-profile design for tight clearance areas

Is this light bar weatherproof and road-ready?

The lens and housing are sonically sealed into a single unit to prevent water intrusion, making the assembly suitable for exposed installations including boat trailers. Its rugged sealed construction helps protect the LEDs and circuit board from moisture, dust, and splash conditions commonly encountered on the road.

• Sonically sealed lens and housing for reliable waterproofing
• Suitable for exposed or partially submerged trailer applications
• Durable chrome bezel resists corrosion and preserves finish
• Designed for DOT-style marker and identification use

How do the electrical connections and functions work?

This dual-function bar has three wires for simple integration: white is ground, gray is low-brightness output, and red is high-brightness output. It operates across a broad 9–16V range, making it compatible with 12V automotive systems and heavy-duty electrical setups on trucks and trailers.

• Wiring: white = ground, gray = low, red = high
• Operating voltage: 9–16 volts for wide vehicle compatibility
• Dual-brightness lets a single bar serve marker and signaling roles
• Works with trucks, trailers, RVs and other 12V systems

Who is this for? This Partsam 12" amber LED light bar is aimed at trailer owners, fleet operators, RV enthusiasts, and pickup or work-truck drivers who need a slim, bright, and weatherproof identification or turn/marker light. If you want a compact, stylish bar that offers dual brightness, straightforward wiring, and a sealed design for exposed installations, this light bar is a practical upgrade for improved visibility and road presence.
