Partsam Amber 12in LED Trailer Light Bar — Clear Lens, Chrome Bezel, Dual-Brightness Sealed

The Partsam 12" amber LED light bar is a slim, sealed dual-brightness trailer light that serves as a turn signal, marker or identification light for trucks, trailers and RVs.

Compact and bright, this 12-inch amber LED bar combines space-saving styling with DOT-friendly illumination. Built around 15 high-efficiency 2835 SMD LEDs and a chrome bezel, it delivers a higher lumen output in a low-profile housing that mounts horizontally, vertically or at an angle. The sonically sealed construction protects the diodes and circuit board from water and road grime, while a universal 9–16 V operating range makes it compatible with most 12V vehicles.

How bright is this Partsam 12" amber LED light bar?

The bar uses 15 high-power 2835 SMD LEDs producing about 460 lumens total, making it noticeably brighter than many stock marker lights. It offers two brightness levels so you can use it for steady marker/clearance lighting and a brighter mode for turn or emergency signaling.

• 15 x 2835 SMD LED emitters for stronger output
• Approximately 460 lumens total light output
• Dual-brightness wiring: low and high modes

Will this light bar hold up to weather, road spray and occasional submersion?

The housing and clear lens are sonically sealed into a single unit, creating a waterproof assembly intended for tough trailer conditions, including boat trailers that see splashes or brief immersion. The sealed design helps prevent moisture intrusion that can damage LEDs or the circuit board.

• Sonically sealed lens and housing to keep out water
• Durable chrome bezel for corrosion resistance and visibility
• Suitable for trailers exposed to spray and wet environments

How do I wire and mount the light on my vehicle?

Mounting is flexible: the slim 11-13/16" length and shallow 9/16" profile allow installation in tight locations, either horizontally, vertically or at an angle. Wiring is straightforward — white for ground, red for high-brightness, gray for low-brightness — and it operates within a 9–16 V range so it works with standard 12V systems.

• Mounting hole spacing: roughly 11 7/16" for easy alignment
• Dimensions: 11-13/16" (L) x 9/16" (W) x 9/16" (H)
• Wiring: white = ground, red = high, gray = low

What vehicles and uses are compatible with this 12" LED bar?

This Partsam bar is designed as a universal DOT-style light for most 12V road and work vehicles. It works well as clearance/marker lights, identification lights, or an emergency/turn signal accent on a wide variety of trucks, trailers and RVs.

• Fits heavy trucks, semi trailers, pickup trucks, utility and horse trailers
• Also suitable for boat trailers, cargo trailers and service vehicles
• DOT-friendly styling and universal 12V compatibility

Who is this for? Installers, fleet managers and DIY owners who need a compact, bright, and weatherproof lighting solution will find this Partsam 12" amber LED bar useful. It’s ideal where space is limited but visibility matters — on tow vehicles, trailers, RVs and other work rigs that require reliable marker, identification or turn signaling without bulk.
