You can look up the proper bulb to use but several of us here use the Sylvania Silver Star Ultra bulb. My Pontiac takes the H11 bulb and you just pop out the old one and put in the new ones, just like replacing a bulb. They are not cheap and are about $50 for two of them at Walmart. Plus they are only good for about 1000 hours which for me was about one year, but they are about the brightest of the white lights (not those idiot blue bulbs) you’ll get with standard bulbs. Still nothing like the daytime light you get with HID or LEDs but quite an improvement anyway.
There are about four different grades of the Sylvania bulb from regular halogen to the Ultra just to confuse people but the Ultra are the ones I use.
