Partswcgg 2.5" Round LED Trailer Marker Lights 13-LED Amber IP67 Flush-Mount for 12V Trailers

Partswcgg 2.5" round LED trailer marker lights are flush-mount, 13-LED reflector clearance and side markers designed for 12V trailers and trucks with a waterproof IP67 housing.

These compact 2.5" round markers combine a miro-reflex faceted reflector with 13 bright LEDs to increase visibility on trailers, utility trucks, horse trailers and other 12V vehicles. They install as flush-mount lights using rubber grommets and standard 2-prong trailer pigtails. Sonically sealed for weather resistance and submersible performance, these marker lights are built to withstand road spray, rain and occasional immersion.

How do these lights improve trailer visibility at night?

The combination of a multi-faceted reflector and 13 concentrated LEDs creates a clearer, more noticeable point of light compared with plain marker lenses. The reflector redirects and magnifies LED output, helping other drivers spot your trailer from the side or rear in low-light conditions.

• 13 LED modules for concentrated brightness
• Miro-reflex faceted reflector increases perceived light output
• Available in amber and red to meet side and clearance color needs
• Flush mounting reduces glare and snag risk while keeping a low profile

What do I need to know about installation?

Installation is simple and tool-light: drill an appropriately sized hole, insert the rubber grommet, and press the light into place—no screws required. Standard 2-prong pigtail wiring makes these compatible with typical 12V trailer electrical systems.

• Recommended hole size: about 2–2/3 inches
• Outer diameter: 3.5 inches; inner visible diameter: 2.5 inches
• Wiring: black = positive, white = negative
• Flush mount height with grommet: approx. 1 inch (depending on insertion depth)

Are these marker lights durable and weatherproof?

Yes—each unit is sonically sealed and rated IP67, which means the housing and lens are designed to resist dust and temporary submersion. That makes them suitable for trailers exposed to road salt, mud, and wet conditions.

• IP67-rated housing and lens for water protection
• Sonic-sealed unit reduces moisture intrusion over time
• Rubber grommet provides vibration cushioning and a tight fit
• Designed for repeated outdoor exposure and road conditions

Can I use the same light for both side marker and clearance functions?

These 2.5" round LED lights can function as either a side marker or a clearance light, but they cannot perform both functions simultaneously from a single fixture. If you require separate side-marker and clearance signaling, install two lights in the appropriate locations.

• Use individually as side marker or clearance lamp
• For both functions, mount two lights—one dedicated to each role
• Color options (amber, red) meet common placement standards
• Ensure wiring follows local trailer lighting codes

Who is this for: Partswcgg 2.5" round LED trailer marker lights are ideal for fleet operators, trailer owners, and DIY mechanics who want low-profile, weatherproof marker and clearance lamps with enhanced reflectivity. They suit semi trailers, utility trailers, horse trailers, pickups, UTVs and other 12V vehicles that need reliable side or clearance illumination without complex installation.
