Partsam 2.5-inch Round LED Side Marker & Clearance Lights — 2-Pack White, Flush-Mount Waterproof 13-LED

These are Partsam 2.5-inch round, 13-LED white flush-mount lights that serve as side marker, clearance, interior courtesy, or auxiliary reverse lights with included rubber grommets and two-wire pigtails.

Small, bright, and weatherproof, this 2-pack of Partsam 2.5" round LED lights provides a compact lighting solution for trailers, trucks, campers, and custom vehicle builds. The clear polycarbonate lens produces a white appearance when lit, and the units install by pushing into the supplied rubber grommet for a low-profile, flush fit. Each lamp contains 13 LEDs for strong, energy-efficient output and comes with a two-wire pigtail for simple wiring.

How will these lights fit into my vehicle or trailer setup?

These flush-mount LEDs are designed for panels where you can cut approximately a 2.66" hole and press the grommet into place. They’re compact enough for cab kits, bumper installs, air cleaner bars, or interior courtesy locations. Because they’re flush-mounted, they minimize snagging and maintain a clean aesthetic.

• Requires ~2.66" cut-out; grommet included for push-in mounting
• 2.5" diameter lamp fits common light panels and custom mounts
• Low-profile design suitable for cab, bumper, or interior locations
• Two-wire pigtail eases electrical connection and polarity testing

What lighting functions can these Partsam LEDs perform?

These lamps are multi-purpose: they can act as side marker lights, clearance lights, ID lamps, interior courtesy lights, or supplemental reverse lamps in custom setups. They are intended to supplement factory lighting or serve specialized functions where additional white illumination is needed.

• Side marker and clearance light capability when mounted correctly
• Useful as interior courtesy or outline lamps for cabins and trailers
• Can serve as auxiliary reverse lights for custom applications (not a DOT-approved primary reverse light)
• Clear lens produces a bright white output from the 13 LEDs

Are these lights durable and weather resistant for exterior use?

The housings and polycarbonate lenses are built for outdoor use and resist moisture and road conditions when installed with the included rubber grommets. The LED design is inherently more shock- and vibration-resistant than filament bulbs, making them suitable for truck and trailer environments.

• Clear polycarbonate lens resists impact and UV fading
• Flush mount with rubber grommet helps seal the panel opening
• LEDs tolerate vibration and frequent on/off cycling
• Wiring pigtail allows connection inside a protected cavity

How do I wire and maintain these 2.5-inch LED lights?

Wiring is straightforward: the two-wire pigtail connects to your vehicle’s 12V circuit and ground. Because the LEDs are low-current, they’re efficient and require minimal maintenance—just keep lenses clean and check the grommet seal periodically for watertight integrity.

• Two-wire pigtail simplifies positive and ground connections
• Low current draw reduces strain on vehicle circuits
• Inspect and clean lenses periodically to preserve brightness
• Replace grommet if it becomes brittle to maintain a tight seal

Who is this for: This 2-pack of Partsam 2.5" 13-LED round lights is aimed at vehicle owners and fabricators who need compact, bright, and weather-resistant auxiliary lighting. Ideal for truckers, RV and trailer owners, custom builders, and anyone adding marker, courtesy, or supplemental reverse lighting to a cab, bumper, sleeper kit, or interior panel. These lamps work best as supplemental or position lights rather than replacing required DOT-approved primary lamps.
