PIAA's number one selling lamps - period. Without question the number one best-selling truck lamp on the market today.
No brush guard should be without a set of PIAA 520's!

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.
