Partsam 4.4" Red 24-LED Trailer Side Marker Light — Pair, IP67 Waterproof, Aluminum Backing

Partsam 4.4" red 24-LED trailer side marker light is a compact, surface-mount clearance/stop/turn/tail lamp with an aluminum backing and IP67 waterproof rating.

These two-piece marker lights combine bright SMD LEDs, a durable polycarbonate lens and a die-cast aluminum backing plate to deliver highly visible signalling for trailers, trucks, RVs and other vehicles. Designed for low-profile mounting, they provide multi-function lighting — tail, brake/turn and side marker — in a single compact housing and include mounting hardware for quick installation.

How bright are these marker lights and will they improve visibility?

The lights use 24 high-power SMD LEDs per unit that produce a strong, concentrated red output visible from the rear and at oblique angles. The polycarbonate lens concentrates and protects the LEDs so light remains punchy even when viewed from the side.

• 24 SMD LEDs per lamp for intense brightness
• Lens shape optimized for rear and side visibility
• Designed to meet common visibility needs for trailers and larger vehicles

What makes the construction durable for roadside use?

Partsam combines a tough polycarbonate lens with a die-cast aluminum backing plate that helps dissipate heat and resists impact better than thinner acrylic lenses. The IP67 rating keeps moisture and dust out, reducing condensation and preserving electronics after exposure to rain or pressure washing.

• Polycarbonate lens resists cracks and chips
• Die-cast aluminum backing plate for thermal management
• IP67 waterproofing keeps internal components dry

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

Each lamp uses a three-wire setup: white for ground, red for high-brightness brake/turn function, and black for lower-intensity tail lighting. The low-profile, surface-mount design ships with zinc-plated screws and nuts for simple attachment to flat surfaces, fenders or frame edges.

• Three-wire color-coded connections for brake/turn and tail functions
• Includes mounting hardware for surface installation
• Compact footprint fits in tight spaces or low-clearance locations

Will these lights fit my vehicle model and where are they best used?

The lights are built to be universal across a broad range of vehicles — trailers, pickups, RVs, campers, buses, tractors and light commercial trucks. Their compact size and rugged build make them suitable for side marker, clearance, tail and auxiliary brake/turn applications wherever extra visibility is needed.

• Universal fit for trailers, trucks, RVs, vans and buses
• Ideal for low-profile mounting to reduce snagging and damage
• Works well as additional side markers, clearance lamps or backup auxiliary lights

Who is this for: These Partsam 4.4" red 24-LED surface-mount marker lights are intended for owners and operators of trailers, pickups, RVs, campers, vans and light commercial vehicles who need a durable, bright, low-profile solution for improved side and rear visibility.
