Ok, FINALLY i decided to give the silverstars a try...... from looking at it side by side in daylight........i did not see any difference at all (disappointing), but than again...its daylight LoL. I guess I'll wait till tonight to take some digital shots and see side by side comparison. Does anyone know if bulbs have to burn in b4 it can really show its performance? BTW, the sylvania silverstar bulbs are smaller in bulb size compared to the Piaa's Xtreme white plus. Not sure if size makes a difference..
