## Before you buy

- The listing calls the lights 5.9 inches in the title and color field, but gives no dimensional drawing. Confirm dimensions, mounting arrangement, wiring compatibility, and whether your application requires a particular lighting certification. The listing describes both a 35-LED white light and a clear acrylic lens, and identifies the product as model year 2018. Its waterproof, durability, and fit claims are not independently verified. Some vehicles may need wiring work.

## In the box

## A good fit for

- Trailer, truck, RV, or other vehicle owners seeking a two-light rear set with reverse or backup functions.
- Buyers whose installation supports 12V DC, three-wire connections, and stud mounting.

## Less suited to

- Buyers needing confirmed dimensions, vehicle-specific fitment, or verified regulatory compliance before purchase.
- Installations that require a different voltage or a wiring arrangement incompatible with the listed three-wire setup.

## Customer feedback

Only aggregate rating information is supplied, with a single rating in the highest category. That is too limited to establish a pattern of customer experience or identify specific strengths and drawbacks. Buyers should base fit and function decisions on the listed wiring, mounting, and vehicle compatibility details.
