Partsam LED Bullseye Side Marker Lights for RV Truck Trailer — Red 5-Pack, 4" x 2", DOT-Approved, 10-LED Low-Profile

This five-light package supplies bright, low-profile red marker lamps built around a bullseye lens with ten LEDs each. Designed for surface mounting, the rectangular 4" x 2" fixtures aim to replace or upgrade older incandescent side and clearance lamps, offering longer life and lower current draw. The units are compatible with commonly found 3" mounting hole patterns and include two-wire connections that exit from the center of the housing.

How bright and durable are these LED bullseye side markers?

Each light uses ten LEDs behind a bullseye-style lens to provide a focused, highly visible red signal that stays noticeable in daylight and at night. The LED design reduces heat and improves longevity versus incandescent bulbs, while the sealed housing resists moisture and road spray.

• 10 LEDs per lamp for concentrated red output
• Sealed surface-mount housing to limit water intrusion
• Lower power draw and longer service life than incandescent
• DOT-approved for legal road use where required

What are the installation details and electrical connections?

Each rectangular lamp measures approximately 100mm x 49mm x 26mm (4" x 2" x 1") with 75mm (2.95") hole spacing for easy alignment to standard brackets and panels. The lights have two wires: red for positive and black for negative, and wires exit from the center of the backplate for tidy routing.

• Size: 100mm x 49mm x 26mm (4" x 2" x 1")
• Hole distance: 75mm (2.95") to match standard panels
• Wiring: red = positive, black = negative; center-exit leads
• Surface-mount design fits cab, sleeper, roof, or side locations

Which vehicles and positions are these marker lights suitable for?

These red bullseye markers are made for heavy-duty and recreational vehicles including trucks, trailers, campers and vans. They work well as side clearance markers, roof or corner indicators, and for cab or sleeper panel lighting on manufacturers such as Peterbilt, Freightliner and Kenworth.

Will these lights meet regulatory and fitment needs?

The Partsam markers are DOT-approved red clearance lights, making them acceptable where regulation-compliant identification or side-marker lamps are required. Their compact footprint and standardized hole spacing simplify replacing worn or noncompliant fixtures without major drilling or modification.

• DOT approval ensures compliance with many vehicle lighting rules
• Compact rectangle fits tight panel spaces and OEM cutouts
• Standardized mounting reduces need for additional brackets
• Center-exit wires allow neat under-panel routing and sealing
