My experience exactly, I've tried the SS and GE in my cars and wasn't impressed with bulb life. I just run an OEM Osram or Phillips for reliability. It looks like I need to give the PIAAs a go. Thanks for the info!
Our eyes are the least sensitive to light in the blue end of the spectrum. I prefer to avoid the cool temperature bulbs. Is the PIAA cool white you use a nice bright white or is it slightly blue? Still have the SV?
