Partsam Trailer Side Marker Lights 4.4" White 2-Pack — 24 SMD LEDs, IP67 Waterproof

These Partsam 4.4-inch white side marker lights are a two-piece set of 24-LED surface-mount lamps designed to serve as reverse, backup, and running lights with an IP67 waterproof aluminum backing for long-lasting roadside visibility.

Whether you tow a trailer, maintain a fleet, or customize an RV or motorcycle, reliable marker lights matter. Partsam's two-pack of 4.4-inch white marker lights combines a high-output 24-SMD LED array with a durable polycarbonate lens and a die-cast aluminum backing plate to manage heat and resist impact. The compact, low-profile housing mounts easily on flat surfaces and includes hardware so you can place them where they improve visibility and reduce collision risk.

How bright and visible are these marker lights at night?

The built-in 24 high-power SMD LEDs deliver intense, evenly distributed white light that increases rear and side visibility after dark. The polycarbonate lens shape focuses light rearward while remaining visible from off angles for safer lane changes and reversing.

• 24 SMD LEDs per lamp for strong lumen output
• Lens design enhances rear and side visibility
• DOT-approved brightness level suitable for trailers and road use

What makes their construction durable and weather resistant?

These markers use a tough polycarbonate lens instead of brittle acrylic, reducing the chance of cracking from impacts. A die-cast aluminum backing plate dissipates heat from the LEDs, extending component life, while an IP67 rating helps prevent water ingress during rain, washing, or wet-road exposure.

• Polycarbonate lens resists impact and discoloration
• Aluminum backing for improved heat dissipation
• IP67 waterproofing prevents condensation and shorting

How do I wire and mount these lights on my vehicle?

The lights use a three-wire system: white for ground, red for high-brightness (reverse/backup), and black for low-brightness running mode. The slim, surface-mount design includes zinc-plated screws and nuts, so installation on trailers, trucks, RVs, or motorcycles is straightforward without bulky housings.

• Three-wire wiring: white ground, red bright, black running
• Surface-mount profile fits tight spaces and flat panels
• Includes mounting screws and nuts for easy installation

Will these fit my trailer, RV, or motorcycle?

These universal marker lights are compact and designed for broad compatibility across trailers, trucks, tractors, RVs, motorcycles, vans, and campers. The low-profile footprint and stainless hardware make them adaptable to aftermarket upgrades or replacements.

• Universal fit for trailers, RVs, trucks, tractors, motorcycles
• Low-profile size reduces snag and collision risk
• Sold as a two-piece set for symmetric mounting or spares

Who is this for: Installers, fleet managers, and owners of trailers, RVs, motorcycles, and light commercial vehicles who want a compact, high-visibility lighting upgrade. If you need rugged, waterproof marker lights with strong LED output and easy surface-mount installation—whether replacing worn lamps or adding reverse/running illumination—this Partsam two-pack provides a practical, long-lasting option.
