Partsam Amber LED Marker Lights 5-Pack — Rectangle 10-LED DOT-Approved 4x2

Partsam 5-pack amber rectangle marker lights are DOT-approved 12V LED clearance/side identification lamps with a double-bullseye lens delivering bright, reliable visibility for trailers, trucks, RVs and campers.

These compact 4" x 2" x 1" LED marker lights provide a high-output, energy-efficient alternative to incandescent lamps. Each unit houses 10 LEDs behind a replaceable snap-on amber lens and comes hardwired with red (positive) and black (negative) leads. The set includes stainless mounting screws and fits a wide range of heavy-duty vehicles and towing equipment where DOT-compliant lighting is required.

How bright are these marker lights and what makes them efficient?

Each rectangular lamp contains ten high-quality LEDs arranged to maximize forward and side visibility while consuming minimal current. LEDs maintain long life and consistent output compared with filament bulbs, so you’ll get brighter performance with less power draw.

• 10 high-intensity LEDs per housing for strong amber illumination
• Lower amperage draw than traditional incandescent bulbs
• Durable lens and sealed housing reduce moisture and corrosion risks

Will these lights fit my trailer, truck, or RV and how are they installed?

The lights are designed as universal rectangular clearance/marker lamps and fit most 12V vehicle lighting applications. Each lamp measures 100 x 49 x 26 mm with a 75 mm mounting hole center distance, and they are supplied with two stainless steel surface-mount screws for quick installation.

• Standard 4" x 2" footprint and 75 mm hole spacing for common mounting locations
• Hardwired with red (positive) and black (negative) leads for direct connection
• Snap-on replaceable amber lens simplifies maintenance or lens replacement

Are these lights DOT-approved and suitable for heavy trucks like Peterbilt or Freightliner?

Yes — the lights are DOT-approved and meet typical identification and clearance lamp requirements for commercial and recreational vehicles. They are suitable as replacements or additions on heavy trucks, trailers, campers and RVs where compliant amber marker lighting is required.

• DOT-approved design for use as side marker and clearance lights
• Compatible with cab, sleeper, fender and roof mounting points on large trucks
• Commonly used on Peterbilt, Freightliner, Kenworth and similar vehicle models

How durable are these marker lights for outdoor and marine-exposed uses?

Constructed for road and trailer environments, the housings and lens retain light transmission while resisting impact and weathering. The stainless steel mounting hardware and sealed body help prevent rust and water intrusion in most typical road and campsite conditions.

• Sealed housing limits moisture entry and protects the LED array
• Replaceable lens design for quick field service without full unit replacement
• Includes corrosion-resistant stainless steel screws for secure mounting
