Bulb Size

Im looking for the bulb size for my 91' accord ex 2door fog lights...i have been lookin everywhere to fin it out and cant seem to find it...the reason why is because i want to put in 3K hid's in them...

I personally would just locate a store that you want to buy them from and call and ask them which ones to use.  That way if they're wrong it's their fault and not yours for requesting the wrong part.

thanks for the sugestion
