I know this is a stupid quetion but I am really confused about this. I am planning to buy a pair of foglight bulb and I fould MTEC Super White 4X Racing Halogen Headlight Bulbs is quite good one along searching the forum.
Can I use that item for foglight bulb?

 

Sure, as long as its a H4 bulb and you are replacing the bulbs in the lower section of the headlight.

 

Yeah. If it's H4 it should fit. Don't go by the fact that they are saying "foglight" bulb. Foglight bulb normally means H3 but not always.
