I'm getting ready to change my fog lights to a H3 6000K Xenon bulb light, but the question is.....Do I really need the ballast for the bulb to work or is it just a plug and play type bulb? Also should I use a 35W or 55W?:dunno:
Yes you do need the ballast. The ballast is what powers the bulb meaning "HID". Dont even start the install until you have the ballast along with Warning Cancellors so you dont get a message on you dash.
