Headlight Bulb Types (SEARCHED)

Yes, I searched and couldnt find a direct answer. I know its a stupid question…

I’m looking to replace my headlight bulbs as well as my turn signals, but im not sure what TYPE of bulbs to get.

I don’t know if watts play a factor or the type of mount, I have no idea what type to get.

EDIT: Realize this is the wrong thread. Check the Electronics section…

Look here for bulb applications:

JDM - H4H

Besides that you just would need to decide what style of light you want to go with. Wattage never made a difference for me except for fogs. I used 100w on my USDM fogs and it ended up melting the lense a few months later. So for fogs go with a 55w or so.
