What to know before buying

Listing details to confirm

The listing is inconsistent about fitment voltage: the title says 12V, while the package description claims suitability for most 12V-24V vehicles. Confirm voltage compatibility before purchase. The title specifies 3/4-inch lights, while the listed overall dimensions are 5.71 x 3.35 x 4.13 inches and do not clarify the measurement basis. Strobe and constant operation are advertised, but how the modes work is unconfirmed.

Who is it for?

A good fit for

Truck and trailer owners looking for a red marker-light set and prepared to hardwire each light.
Installations where the described separate marker-light and turn-signal wiring is useful.

Less suited to

Buyers who need plug-and-play lights or a confirmed voltage range before wiring.
Shoppers who need a confirmed switching method for strobe and constant modes.

Aggregate customer ratings are mostly five-star, with some lower ratings also present. That offers a broadly favorable but limited signal about customer experience, not evidence about brightness, waterproof performance, wiring ease, or the disputed voltage details. Buyers should weigh those unresolved fitment and mode questions against the rating summary.
