Unity has been an innovative manufacturer of automotive, truck and emergency vehicle lighting products for over 80 years. The company was started in 1918, on the south side of Chicago. The company evolved into single, private ownership under Henry Rue Gross in 1923. In the mid-1920’s, Unity started production of its line of post-mount spotlights. The company expanded into the manufacture of automotive and heavy-duty truck road lights in the 1930’s. Shortly after moving to its current 160,000 sq. ft. facility in 1960, Unity was able to expand into the manufacture of emergency lighting products for police, fire, and other emergency vehicles.

Throughout the history of motorized vehicles, Unity has adapted to customer needs and made products that improve the safety of motorists, truckers, off-roaders, police, fire, ambulance, utility, military, farmers, wreckers, snow plows and services vehicles of all kinds during nighttime activities and emergencies.

Today, Unity is the world’s largest manufacturer of post-mount spotlights. The company is also a major OE supplier of both auxiliary and emergency lighting products. Its product range includes post-mount spotlights, roof-mount spotlights, fog lights, driving lights, off-road lights, work lights, hand-held spotlights, deck lights, 360 degree warning lights and custom wire harnesses.

Unity’s commitment is to produce products that exceed customer expectations, achieve the highest level of quality while offering our customers exceptional value.
