Partsam 2Pcs RED AMBER LED Trailer Fender Lights Bullet LED

These Partsam two-piece fender marker lights combine an amber front-facing LED and a red rear-facing LED in a compact, pre-wired assembly to mark trailer width and improve visibility.

When towing wider trailers you need simple, durable marker lights that mount to the fender and clearly show the trailer’s widest points to other drivers. The Partsam Fender Light Set arrives as a left and right assembly with sealed lenses, a low-profile housing, and a 2-wire hookup for quick installation. They are DOT compliant and designed for trailers wider than 80 inches.

How do these lights install on my trailer?

Installation is straightforward: the assemblies are pre-wired and designed to mount on the top or side of a fender, indicating the trailer’s outer edges. The two-wire system requires a power lead and a ground connection, and the compact housing sits flush to minimize snagging.

• Pre-wired assemblies for left and right fenders (no mounting screws included)
• Two wires: black = positive, white = negative (ground)
• Mounts on top or side of fender; suitable for trailers over 80" wide
• Low-profile housing reduces exposure to road debris and contact

Which light faces which direction and why does that matter?

Each assembly includes one amber LED pointing toward the trailer’s front and one red LED pointing rearward. This orientation follows standard color coding for clearance lights so other road users can quickly interpret the trailer’s direction and dimensions.

• Amber LED faces forward to serve as a front clearance marker
• Red LED faces rear to indicate the trailer’s back edge
• Sealed lenses protect LEDs from water and dirt, maintaining visibility

Are these lights durable and compliant for road use?

The Partsam fender lights use single-diode LEDs in a sealed, low-profile housing that resists moisture and impact from typical road conditions. They meet DOT standards, making them appropriate for on-road trailers when installed correctly.

• DOT compliant construction for legal on-road use
• Sealed, waterproof lenses to resist weather and splashes
• Compact 3/4" round LED modules in a durable housing

What wiring and maintenance should I expect?

Wiring is a basic two-conductor hookup: connect the black lead to power and the white lead to ground. Maintenance is minimal—periodic checks for secure mounting and clean lenses ensure continued brightness and visibility.

• 2-wire design: black positive, white negative (ground)
• Occasional cleaning of lenses and inspection of wire connections recommended
• No internal bulbs to replace; long-life LEDs reduce upkeep

Who is this for: The Partsam 2-piece fender marker light set is intended for trailer owners, fleet operators, and DIY mechanics who need a DOT-compliant, low-profile solution for marking the outer edges of trailers wider than 80 inches. It suits boat trailers, utility trailers, car haulers, and any towing setup requiring clear front and rear clearance indication with easy mounting and simple wiring.
