Partswcgg Rectangular LED Trailer Tail Lights 4‑Pack 5x3 Red — 12‑LED, IP67 Waterproof, 3‑Prong Pigtail

Partswcgg 4Pcs 5x3 Rectangular LED Trailer Tail Lights are a four-piece set of 12-LED red rear lamps designed to deliver stop, turn and running light functions for 12V trailers and trucks with IP67-rated sealing.

These 5x3 rectangle LED tail lights combine compact sizing with durable sealing and three-conductor wiring to simplify upgrades or replacements on flatbeds, utility trailers, trucks and other 12V vehicles. Each lamp houses 12 bright LEDs in a low-profile housing and ships with rubber grommets and three-prong pigtails for straightforward plug-and-play installation without hardwiring. The lights are rated to resist water and road grime, making them suitable for varied weather and hauling conditions.

How bright and visible are these LED trailer tail lights?

Each lens contains 12 LEDs that produce a distinct red output for stop/turn and a lower-intensity output for running lights. The LED array is arranged to maximize visibility from common rear viewing angles on the road and at the trailer hitch.

• 12 LEDs per light deliver clear illumination for stop, turn and tail functions
• Dual-mode wiring separates high (stop/turn) and low (running) outputs
• Red lens optimized for regulatory visibility in traffic

What size are the lights and how do I mount them?

The nominal lamp face is approximately 5.14" x 3.27" with an overall bezel near 6.25" x 4.26"; an installation hole around 5-5/8" is often needed. Each unit is supplied with a rubber grommet and a 3-prong wire pigtail so you can secure the lamp in a cutout and connect to a standard 12V trailer circuit.

• Light-only dimensions: 5.14" x 3.27" x 1.00"
• Overall bezel size: 6.25" x 4.26" x 1.00"
• Supplied rubber grommet and 3-prong pigtail for mounting and connection

How does the wiring work and what functions are supported?

Wiring is broken into three conductors: white for ground, red for the higher-output stop/turn/brake circuit, and black for the lower-intensity tail/running circuit. This arrangement lets a single lamp perform multiple standard rear-light roles on typical 12V vehicle wiring harnesses.

• White = ground; black = tail/running; red = stop/turn/brake
• Pre-attached pigtails simplify hookup to existing trailer wiring
• Compatible with common 12V trailer and truck electrical systems

Are these lights weatherproof and suitable for heavy use?

Yes—the housings are silicon-sealed and carry an IP67 level of protection against water and dust ingress, making them resilient for road spray, mud and most wet conditions. They’re designed for general-purpose commercial and recreational vehicle use but standard maintenance and inspection are advised for long-term reliability.

• High-grade silicone sealing for durable water resistance
• IP67-rated against dust and temporary immersion
• Intended for repeated road use on trailers, trucks and utility vehicles
