can these HB4 bulbs be used on the main headlamps as well as the fog lights?
I would alos like to change to more 'white' lights as opposed to the standard yellow.
I looked up the link and the Phillips bulbs are referred to as having a blue effect, are they really blue? Don't want to look like a spide!!!
Thanks, found this link really useful but just want to double check the colour before i spend £23 per bulb!
