what is the bulb that fits the stock fog light kit for an 07 civic si 4dr cause someone gave me some free yellow hid fog lights but i dont have fog lights on it right now are the bulbs h1??

 

h11

 

If they gave you an hid kit for free and they use amp connectors, you might just buy new bulbs to fit the housing.
Unless you're referring to HIDs as those halogen bulbs that on the package says XENON

 

If they are H1, they most likely have amp connectors, whether they are true HID bulbs or not. For an HID bulb, the connector would just be on the end of a wire. But, they wouldn't fit correctly in the H11 foglight housing anyway, so they'd be useless for an 8th gen civic.

 

so the stock ones are h11??

 

Yes...which would be why I said "h11".
