Partsam LED side marker lights Red 5‑Pack 4" Rectangular Bullseye — DOT‑approved 10‑LED visibility

The Partsam 5-piece red double-bubble bullseye LED side marker set is a DOT-approved surface-mount lighting kit designed to replace or upgrade clearance and marker lights on trucks, RVs, trailers and motorhomes.

These compact 4" x 2" rectangular LED marker lights combine a distinctive bullseye lens with a bright 10-LED array to improve vehicle visibility and match standard mounting patterns. Built for exterior vehicle use, the lamps use a two-wire connection (red positive, black negative) and are sized to fit many OEM mounting locations on cab panels, sleepers, bumpers and roof edges. The low-profile housing and tiger-eye styling make them suitable for heavy trucks such as Peterbilt, Freightliner and Kenworth, as well as RVs and campers.

How bright and durable are these LED bullseye side markers?

Each marker contains 10 high-efficiency LEDs behind a bullseye lens, providing concentrated light output and good lateral visibility. The sealed housing resists road moisture and grime for dependable performance outdoors.

• 10 LEDs per unit for clear illumination
• Sealed surface-mount housing resists water and dust
• Durable lens and casing for road vibration and impact

Will these lights fit my truck, trailer or RV mounting holes?

The fixtures are sized to match common aftermarket and OEM hole patterns so they slide into many standard locations without modification. Measure your panel before installation to confirm compatibility.
