Partsam 4" Round Red LED Trailer Tail Light 4 Inch Flange Mount, 24-LED IP65 Waterproof Stop/Turn/Tail

Partsam 4" round red LED tail lights are compact, multi-function trailer lamps that combine stop, turn and tail light duties in a single waterproof flange-mounted assembly.

These 4-inch LED lamps are built for trailers, RVs, trucks and utility vehicles that need a bright, reliable rear lighting solution. Each light packs 24 high-intensity red LEDs into a low-profile housing with a flange mount for fast surface installation. The hardwired 3-conductor setup ties into standard 12V DC systems and the IP65-rated enclosure helps keep moisture and road debris out, so the lights keep performing in wet or dusty conditions.

How bright and visible are these lights on the road?

The lens contains 24 super-bright red LEDs that produce a sharp, easily noticed signal for stopping, turning and running lights. LED technology ensures quick illumination and consistent brightness over time without filament failures.

• 24 high-intensity red LEDs for clear signaling
• Distinct stop/turn versus tail brightness via separate wiring
• Quick-response illumination improves visibility at night and in traffic

Will these fit my trailer and how are they mounted?

These lamps use a flange mount designed for surface installation and require a roughly 4.38-inch mounting hole. The compact 4-inch diameter housing works well on narrow mounting areas and on a variety of trailers and RV rear panels.

• Flange-mounted for straightforward surface installation
• Approximate 4.38-inch cutout needed for flush placement
• Low-profile housing suitable for most standard trailer panels

How do I wire and power these LEDs?

Each lamp uses a three-wire hardwired configuration that connects directly to a 12V DC trailer electrical system. The color-coded wires separate ground, high-brightness stop/turn, and low-brightness tail functions for simple integration with most vehicle harnesses.

• Three-wire setup: gray = ground, red = stop/turn high brightness, green = tail low brightness
• Designed for standard 12V DC automotive trailer systems
• No sockets or bulbs to replace—solid-state LEDs reduce maintenance

Are these lights durable and weather resistant?

The lights have an IP65 rating to protect against rain, splashing water and dust, making them suitable for outdoor use in changing weather. The sealed housing and rugged lens resist road grime and routine exposure, helping maintain consistent performance.

• IP65 waterproof rating for protection against rain and dust
• Sealed construction resists road debris and moisture ingress
• Durable housing designed for regular trailer use and exposure

Who is this for: These Partsam 4" round red LED stop/turn/tail lights are ideal for trailer owners, RV enthusiasts, pickup and truck fleet managers, and anyone needing a compact replacement rear lamp with multi-function capability. If you want an easy-to-mount, low-maintenance LED solution that fits standard 12V systems and stands up to outdoor conditions, this set of four lamps delivers a practical, bright and weather-resistant lighting upgrade.
