Which is the best super yellow or white bulb for the 08 GS350 fog light to match the headlight white color?

I was wondering if anyone can help me on this? Which is the best fog light bulb replacement to match the headlight color (white)? or is there a super bright yellow that%26#039;s brighter than the stock (faded yellow)? Can i just change the bulb or do i have to do a conversion to a HID?|||White bulb...
