Partsam 4-inch Round Red LED Trailer Tail Lights 4-Pack — 24-LED Flange Mount, IP65 Waterproof

Partsam 4" round red LED stop/turn/tail lights are a four-piece, flange-mount LED lighting set that delivers bright 24-LED signaling for trailers, RVs, trucks and utility vehicles on 12V systems. These compact, weatherproof lights combine stop, turn and tail functions in a single housing to simplify installation and improve visibility on the road. Each lamp uses 24 super-bright red LEDs in a durable, IP65-rated shell and fits standard 4-inch mounting openings with a flange-style installation. The hardwired three-conductor setup (gray ground, red stop/turn, green tail/running) makes these lights compatible with most trailer wiring configurations and common 12V DC electrical systems.

How do these lights improve roadside safety and visibility?

The 24 red LEDs produce a consistent, high-intensity signal for braking, turning and running lights, helping other drivers notice your vehicle sooner. The multi-function design concentrates necessary signaling into one compact fixture, reducing the number of separate lamps needed on a trailer or RV.

• 24 super-bright red LEDs for clear signaling day and night
• Stop, turn and tail functions in a single lamp to simplify layout
• Even light distribution reduces glare and dark spots
• IP65 protection keeps LEDs visible in rain and dust

What installation steps and wiring should I expect?

Each lamp is flange-mounted and requires a roughly 4.38-inch mounting hole for proper placement and fit. The lights use a three-wire hardwired connection: gray for ground, red for high-brightness stop/turn, and green for low-brightness tail/running light.

• Flange mount design for quick surface installation
• Approximate 4.38" mounting hole required for each light
• Three-conductor wiring simplifies tie-in to existing trailer harness
• Designed for standard 12V DC vehicle electrical systems

Are these lights durable enough for outdoor and heavy-duty use?

The housing and lens are engineered to meet an IP65 waterproof rating so the fixtures resist rain, splashing water and road debris, making them suitable for most outdoor and on-road applications. The LED components are long-life compared with incandescent bulbs, reducing maintenance and bulb replacement frequency.

• IP65-rated waterproof protection against rain and dust
• Solid sealed assembly prevents moisture intrusion
• Long-life LEDs lower maintenance compared with bulbs
• Rugged design for trailers, RVs, trucks and work vehicles

Will these lights work on my vehicle’s electrical system?

Yes—these lights are built for universal fit on standard 12V DC systems, commonly found on trailers, RVs, light trucks and semi-trailers. Confirm your wiring colors and functions match the three-conductor configuration for straightforward integration.

• Compatible with 12V DC electrical systems
• Three-wire hardwired setup matches typical trailer harnesses
• Works on trailers, RVs, trucks, and utility vehicles
• Reduces retrofit complexity thanks to universal wiring colors
