I want to replace the bulbs on my halo headlights on my 95 Jetta to halogen headlights but im not sure what size to look for or how to getthem. I am talking about the bulbs for the normal headlights not the high beams or the halos.Although I would like to replace the halo lights too to get quality brighter bulbs too.I got them online and have no idea of the specifics of them so any advice would help thanks.

 

The bulbs were size 9004 for stock jetta headlights, but i need the bulbs for the jetta halo headlights.

 

do i have to buy a whole HID kit or can i just replace the bulbs?
