Best 40 inch LED Light Bar Reviews

Forty-inch LED light bars are a great choice when seeking extreme illumination and a lower price compared to a full-size 50-inch model.

Most manufacturers offer this size, so you have a wide array of lighting capabilities, LED configurations, beam patterns and prices from which to select.

Although most buyers mount a 40-inch light bar overhead above the windshield, on a rack or on the roof, this size fits well in grills and below the bumper too. They make an outstanding scene illumination light for emergency or public service vehicles as well.

The KC HiLites 337’s brightness falls in between the Black Oak and the Tuff Stuff light bar as does its price. It is built for rugged trails, ice, snow, fording creeks and lots of dust. The low-profile reduces air resistance, while offering a sleeker look than other dual-row light
