I am trying to select between the PIAA 510 and 540 Ion Crystal Fog light based on the most up to date information and personal experiences out there.
My bumper will fit either a 510 with the PIAA grill or the 540 with out the grill. My understanding is both versions use the same bulb. Since the 540 lamp is larger does it perform better or worse than the 510 smaller sized lamp...?
Which lamp would perform the best?
Where is the best place to purchase PIAA these days?
