will a h4 bulb work n a jdm eg headlamp. i know they are supposed to use a h4h. what is up side and a down side thanks

 

H4H has a narrower base so unless you modify the H4's base it won't fit period and even if you did you have no way of knowing for sure that you've got everything lined up evenly. You can find H4H bulbs on ebay for around 30 bucks last time I checked...

 

here ya go

Yeah but those are not for hids. Im looking for some too. Or i might just modify mines to fit.

 

All the H4H hid kits I've seen are low beam with no glare shield which leads to pist off people...

 

So maybe i should just try to modify my kit then.

 

he didnt say he was looking for hid h4h bulbs just asking if h4 would fit.
pnp hids suck! h4h hid lights dont have glare sheilds, your going to **** a lot of people off with them

 

they wont fit, the base of an h4 is bigger then h4h, i know cause i have h4h headlamps and tried h4 and they wont fit
