Partsam 4" Round Dual-Color LED Tail Lights 2-Pack — Red Stop/Turn + White Backup, 19-LED, IP65, 3-Prong Pigtails

Partsam's 2-pack 4" round dual-color LED lights combine stop/turn/tail red illumination with an integrated white backup lamp in a weatherproof housing.

These dual-function LED units are designed for trucks and trailers that need compact, visible rear lighting with easy installation. Each lamp houses 19 diodes that emit red for stop/turn/tail functions and white for reverse, and the kit includes rubber grommets plus standard three-prong offset wire pigtails and an extra bullet plug for the backup circuit. The lights run on 12V DC, carry an IP65 splash-resistant rating, and have overall dimensions intended to fit common 4.7" rubber grommets.

How do these lights fit my trailer or truck?

The lights are sized to accommodate most standard 4" mounting holes and commonly used rubber grommets. With a 5.3" outer diameter and 1.2" profile height, they sit flush in many rear lamp cutouts and include grommets for a secure fit.

• Overall diameter: 5.3 inches; height: 1.2 inches
• Fits roughly 4.7" standard round rubber grommets
• Includes rubber grommets for vibration dampening
• Low-profile design clears tight mounting pockets

What wiring and connectors are included, and how do they work?

Each lamp ships with a standard three-prong offset wire pigtail plus a short yellow lead with a male bullet plug for the backup lamp. Wire color coding simplifies hookup: white is ground, black is tail (low brightness), red is stop/turn (high brightness), and yellow powers the white reverse LEDs.

• Standard three-prong offset pigtails for easy replacement
• Yellow bullet-style plug for reverse lamp circuit
• Clear color coding to match typical trailer wiring
• Plug-and-play style for quick swap-in installations

How bright and durable are the LEDs in everyday use?

The assembly uses 19 high-quality diodes per lamp to provide bright, distinct red brake/turn/tail output and a crisp white reverse light. The housing carries an IP65 rating for protection against rain and road spray, making it suitable for general trucking and trailering environments (not for submersion).

• 19 LED diodes for clear visibility in both colors
• IP65-rated housing for weather resistance
• Operates on standard 12V DC electrical systems
• Recommended two red stop/turn lamps when using reverse white override

Who is this for: This kit is made for owners and operators of trucks, trailers, and heavy-duty vehicles who need compact, dual-function rear lighting that replaces standard 4" round units. It’s particularly useful for fleets and DIY mechanics who want a straightforward, weather-resistant LED solution with plug-style wiring for faster installation on vehicles such as Peterbilt, Kenworth, Freightliner, and similar rigs.
