2.5in Round LED Trailer Marker Lights 10-Pack - Bright, Waterproof

Our review of these 2.5in round LED trailer marker lights finds them ideal for owners who need a simple, durable lighting upgrade. The biggest reason to buy is straightforward: ten ultra-bright red LEDs in a compact, weatherproof housing give clear daytime and nighttime visibility for trailers, trucks, RVs and campers. Installation is uncomplicated for most users thanks to the included grommets and pigtails, and the IP67 rating means the lights hold up well outdoors, making this set a practical replacement for failing incandescent markers.

Key Features

• Ultra-Bright LEDs: Four high-intensity diodes per light produce a noticeably brighter marker signal that improves visibility in daylight and at night.
• Ten-Light Pack: The pack includes 10 matching round lights so you can outfit an entire trailer or replace all side markers at once for consistent lighting.
• Weatherproof Construction: An IP67 rating helps ensure reliable operation in rain and harsh conditions without premature failure.
• Easy Installation: Each light ships with grommets and wire pigtails to simplify mounting and wiring on common trailer and truck panels.
• Multi-Application Use: The compact 2.5in round shape works well as side marker lights, clearance lights, cab roof markers and fender lights for a range of vehicles.
• Durable Design: The LED assembly is built for longevity so owners can expect extended service life compared with older incandescent bulbs.

Who It's For

These lights are best suited to trailer, truck and RV owners who want a practical, affordable upgrade from incandescent markers and need consistent, bright red side or clearance lights. They appeal to DIY installers who are comfortable cutting mounting holes, pushing in grommets and connecting simple pigtail wiring for a quick swap.

Those who should look elsewhere include buyers who require integrated mounting brackets, factory plug compatibility for uncommon connectors, or a specific OEM-certified lens shape. If the supplied grommets or pigtail plugs do not match your trailer harness, expect to do a little additional wiring or use adapter fittings.
