Dimensions matched perfectly. Fit my existing mounting pattern with no mods. Clear lens + white LED gives true color output—no blue or yellow tint.

Great Value for Heavy-Duty Use
Compared several brands—this one had the best combo of price, brightness, and build. At $20, it’s half the cost of some OEM units but works just as well.

Excellent for Auxiliary Use
Using this as a backup and work light on my utility trailer. Mounted it low and angled slightly down—lights up the entire work area. Draws very little power, even after long use.

Fully Waterproof – No Fogging
Installed before a storm and tested in deep puddles. Zero moisture inside the housing. Seals are tight and the flange sits flush. Critical for all-weather reliability.

Slight Tint in Lens, But Still Effective
The lens looks slightly milky in direct sunlight, but once powered, brightness is excellent. Waterproof seal held up after a week of downpours. Solid build for $20.
