Welcome to the forum and congratulations on the new purchase! Bulbs are H4/9003, I run the cheap LED bulbs from ebay, they are much brighter but do not project very far, but that's what light bars are for. Or you can buy the better conversion kits and get the real deal. Here is a link to a company that has a wide variety https://www.superbrightleds.com/search/led-products/9003 led/
