Partsam 5pcs 2 inch Red Round LED Lights
Best for: fleets or DIYers needing a ready-to-install set for multiple locations. Why selected: 5 red 2″ round lights with a grommet/pigtail kit simplify installation. These are sealed for water exposure and can serve as side marker or clearance lights. The reflex lens helps visibility at a distance, and the kit supports complete wiring for 12-volt systems. Limitation: only red in this kit, so you’ll need additional amber units if you require both marker and clearance colors in one install.
FXC 4Pack 2-Inch Round LED Lights
Best for: users who want a mix of amber and red markers with strong waterproofing. Why selected: Each light contains 9 diodes with reflex reflectors for wider angles and higher visibility, and the sealed design resists sand, dust, water, and snow. Easy 2-prong plug installation with grommets and pigtails, though you may need to drill a hole of about 2.25″ to 2.3″ for the grommet to fit. Limitation: outer diameter is 2.5″ while inner light measures around 2″; ensure your mounting hole size matches.
Partsam 10Pack Amber/Red 2″ Round Lights
Best for: cost-conscious buyers upgrading multiple trailers or RVs. Why selected: DOT Approved, includes 5 amber and 5 red units with reflex lenses for dual-function marking and clearance. The 2″ round, flush-mount design comes with standard grommets and pigtails. Heavy-duty waterproof housing supports submersion. Limitation: mixed color set means you’ll want to track color-specific wiring for correct signaling on different trailer sections.
Partsam 2pcs Red 2″ Round Lights
Best for: small vehicle applications or replacements where only red clearance/marker lights are needed. Why selected: a compact package that includes grommets and pigtails, making flush-mount installation straightforward. Submersible, 12-volt operation keeps performance consistent in challenging weather. Limitation: limited color options in this pack; only red is offered here.
EclatLights 10Pack Round Marker Lights
Best for: high-visibility fleets or campers needing a balanced amber/red set. Why selected: a DOT-certified 10-pack containing 5 amber and 5 red units, with IP67 waterproofing and 4 LEDs per light for strong daytime and nighttime visibility. 2-prong plug compatibility and included grommets/pigtails simplify DIY installs. Limitation: grommet sizing requires a close hole fit; ensure hole preparation aligns with your mounting plan.
Buying Guide: Key Purchase Considerations
What color scheme do you need? If you require both marker and clearance functions, a mixed amber/red set may reduce part counts and ensure consistent signaling. How weatherproof should lights be? Look for IP67 or higher, and submersible claims for off-road or coastal use. Is DOT approval important? For commercial fleets and regulated haulers, DOT-certified options offer compliance clarity. What installation approach works best? Flush-mount designs with grommets are DIY-friendly, while sealed housings support rugged environments. Do you need ready-to-wire kits? Kits with pigtails simplify wiring for standard 12V systems. Consider hole size and grommet compatibility to avoid drilling beyond what’s needed.
