Partsam 4.4" Amber 24-LED Trailer Marker Lights - DOT Approved, IP67 Waterproof Aluminum Surface Mount

Partsam 4.4" amber 24-LED marker lights are compact, DOT-approved surface-mount signal lamps that deliver bright amber brake/turn and side-marker illumination for 12V trucks, trailers, RVs and tractors.

These low-profile lights combine a durable aluminum housing, a polycarbonate lens and 24 high-output SMD LEDs to provide clear, energy-efficient signaling and side-marker visibility in wet or rough conditions. Each lamp uses a three-wire configuration (high-brightness brake/turn, low-brightness park/marker, and ground), ships with a gasket and stainless mounting hardware, and meets DOT standards so you can replace or upgrade vehicle marker lights with confidence.

How bright and visible are these marker lights?

The 24 SMD LEDs in each 4.4" assembly produce a vivid amber output designed to be seen in daylight and at night. The LEDs provide faster illumination than incandescent bulbs, helping other road users notice braking and turning more quickly.

• 24 high-power SMD LEDs per light for strong amber output
• Designed for both brake/turn (high) and parking/marker (low) modes
• DOT-approved for regulatory visibility standards

Will these lights hold up to weather, road vibration, and corrosion?

Yes — the lens is polycarbonate and the body is corrosion-resistant aluminum, built to resist impacts and vibration commonly encountered on trailers and trucks. An IP67 rating means the units are protected against dust and temporary immersion in water, so they continue operating through rain, snow and road spray.

• Aluminum housing resists rust and mechanical wear
• Polycarbonate lens resists cracking and UV degradation
• IP67 waterproofing keeps electronics dry in heavy weather

How simple is installation and wiring on a 12V vehicle?

Installation is straightforward: these are surface-mount lights that come with a gasket and mounting screws for a sealed fit. The three-wire wiring makes hookup clear—connect high (brake/turn), low (parking/marker) and ground—so they integrate with standard 12V vehicle circuits.

• Includes gasket and screws for secure surface mounting
• Three-wire harness: red=high, black=low, white=ground
• Lightweight, low-profile design fits tight locations

Are these marker lights compatible with my truck, trailer, or RV?

They are intended for 12V systems and work as brake/turn/parking side markers on a wide range of vehicles including trucks, trailers, tractors, RVs, buses and MPVs. Their compact 4.4" size and surface-mount style suit many retrofit and replacement applications.

• Specifically for 12V vehicle electrical systems
• Works as brake, turn signal, and side/parking marker light
• Ideal for trailers, trucks, tractors, RVs, buses and utility vehicles

Who is this for: Drivers, fleet managers, and DIY vehicle owners who need a durable, DOT-compliant amber marker light that’s easy to install and built to withstand the elements. If you want a compact LED upgrade for improved visibility and lower power draw compared with incandescent markers — for trailers, farm equipment, commercial trucks or recreational vehicles — these Partsam lights are a practical choice.
