For those who prefer the look of a "clear" lens, the 520 SMR features PIAA's computer-designed Super Multi-Surface Reflector technology. SMR technology reduces stray light providing an extremely focused beam pattern without the use of lens fluting. The number one, best selling light on the market today. The 520 complements more trucks and SUVs than any other light available. The reason? Simply the best combination of fashion and performance in its class.
