HELLA auxiliary lamps are legendary for their ruggedness and dependability. Every one of our lamps must pass a series of endurance tests before we will brand it "HELLA". HELLA's 550 Series lamps have always been a top-seller. These lamps have everything it takes to be HELLA - world-class quality, brilliant performance, and off-road durability, all with great affordability. You get an impact-resistant reinforced ABS housing, bonded water-tight lens, and an aluminum vapor-coated reflector. The HELLA 550 Series lamps are at home either on or off the road on cars, trucks, SUV's or any other vehicle that requires high performance, rugged lighting. Their light weight and easy one-stud mounting make installation quick and simple so that you can spend less time mounting and more time driving. All of these things combine to make the HELLA 550 Series the obvious choice for anyone wanting a rugged, easy to install high-performance driving lamp at a competitive price.
