Partswcgg 2" Round LED Trailer Marker Lights 20-Pack (10 Amber + 10 Red) 9-LED 12V Low-Profile Flush-Mount

Partswcgg's 20-piece set of 2-inch round LED trailer marker lights includes ten amber and ten red 9-LED flush-mount lamps for 12V vehicles, designed for clear side-marker or clearance-light visibility.

Whether you maintain a fleet, outfit a trailer, or keep an RV road-ready, this kit supplies a matched pair of safety lights in two colors so you can replace worn fixtures in one go. Each lamp is a compact, low-profile round unit with a two-prong pigtail and nine bright LEDs that run on standard 12-volt systems. The lights are built for universal fitment across trucks, trailers, RVs, buses, ATVs and similar vehicles, and come with clear installation dimensions to simplify mounting.

How do these 2" LED marker lights improve nighttime and daytime visibility?

Each fixture houses nine LEDs arranged to throw a wide, even beam that’s easier for other drivers to spot at distance. The combination of amber and red lamps delivers standard front/side and rear/side color coding so your vehicle presents clear signals in traffic.

• 9 high-intensity LEDs per housing for consistent brightness
• Amber for front/side or clearance use; red for rear/side or clearance use
• Low power draw suitable for extended use without battery drain

Will these lights fit my trailer or vehicle and how are they wired?

The lights are made for universal 12V systems and are designed to be flush-mounted into a roughly 2-1/4" hole, with outer and inner diameters specified for accurate drilling. Each lamp includes a two-prong pigtail: black is positive, white is negative, which makes hooking them into typical trailer harnesses straightforward.

• Outer diameter: 2-7/8"; inner diameter: 2"; recommended mounting hole ~2-1/4"
• Two-prong pigtail included for simple electrical connection
• Designed for 12V DC systems used in trailers, trucks, RVs, and more

Can these markers serve as both a side marker and a clearance light on the same mount?

Each lamp can function as either a side marker or a clearance light, but it cannot legally replace both roles simultaneously from a single unit in most installations. If you need dual-function coverage at the same mounting point, install two separate lights or follow local vehicle codes to ensure compliance.

• Use individually as side marker or clearance light, not both
• Install a second lamp if both signals are required at the same location
• Check local regulations for placement and color requirements

What should I expect during installation and maintenance?

Installation is straightforward for anyone comfortable drilling and wiring small trailer lights. The grommet-mounted design sits flush when pressed in; height varies by how far it’s inserted. For maintenance, LEDs require less frequent replacement than incandescent bulbs, but ensure connections remain dry and corrosion-free.

• Grommet flush-mount profile; insertion depth affects visible height
• Drill a ~2-1/4" hole, press light into grommet for secure fit
• Inspect wiring and seals periodically to prevent water intrusion

Who this is for: This 20-piece Partswcgg kit is ideal for fleet owners, trailer builders, RV enthusiasts, and DIYers who want a matched set of reliable 2" LED marker lights in both amber and red. It’s a practical purchase if you need immediate replacements for multiple vehicles, prefer standardized parts across a fleet, or want to keep spare lights on hand for quick roadside swaps. For installations requiring both side-marker and clearance functions at one location, plan to mount additional fixtures to meet safety and legal requirements.
