4 in Round Dual Revolution LED Tail Lights - Dual Red and White

In this review the 4 in Round Dual Revolution LED Tail Lights are examined for drivers who need a compact, dual-function lighting solution for trailers, trucks, RVs and Jeeps. The single biggest reason to consider these lights is their dual-color design: a red stop/turn/tail function that switches to a bright white backup light, combining two lamps in one low-profile unit and simplifying wiring and mounting for flush installations.

Key Features

• Dual-color LEDs: The light uses 19 LEDs that provide distinct red and white output, allowing a single fixture to serve as both tail and backup lighting for improved visibility.
• Complete installation kit: Each package includes two 3-prong trailer wire pigtails, rubber grommets and chrome plated visors, which speeds up fitment and gives a finished look.
• Simple wiring: Color-coded leads make setup straightforward: white is ground, red is stop/turn, black is tail running and the auxiliary plug drives the backup white LEDs.
• Flush mount fit: The lights are roughly 5.1 in diameter and 1.1 in deep and require a 4.5 in hole for a neat flush installation with the provided grommet.
• Weatherproof construction: Sonically sealed and rated IP67, these lights are submersible and suitable for exposed exterior use on trailers and service vehicles.

Who It's For

This product is aimed at owners of trailers, semi trucks, RVs, service trucks and off-road vehicles who want a compact, combined stop/turn/tail and reverse light in a single 4 in housing. It is especially useful for those doing a clean flush mount installation who appreciate the included grommets and chrome visors.

Those who need ultra-high brightness for long-range signaling or who require custom lens colors should look elsewhere, since feedback on brightness is mixed and the light is designed as a compact dual-function unit rather than a high-output lamp for long-distance visibility.

Pros & Cons

Pros

• Combines red tail/stop/turn and white backup lighting in one compact 4 in housing.
• Includes mounting hardware and pigtails for a faster, cleaner installation.
• IP67 waterproof and sonically sealed for reliable performance in wet conditions.

Cons

• Brightness receives mixed feedback, so users expecting very high lumen output may find it modest compared with larger LED housings.

What wires control each function?
White is ground, red is stop/turn brake, black is tail running and the auxiliary blue bullet plug powers the backup white LEDs.

Will these fit a standard trailer light hole?
They require a 4.5 in hole and sit roughly 5.1 in across, so verify panel clearance for a flush install.
