Yes, H4 outer and H3 inner. I've heard it said that the old housings only really work with the 360 degree design of the Halogen bulb and your best bet for brighter lights is a relay kit. Apparently an LED will have dead spots since it is not a true 360 degree bulb but I haven't personally tested that claim. If you are going to get LED make sure you get headlight bulbs and not just the same fitment. True headlight bulbs will have a dome on the back side for air cooling. Bulb pricing is all over the map! Not sure what an expensive bulb really gets you vs. a Chinese import.
For Halogen H4 & H3 bulb selection try https://www.rallylights.com/light-bulbs they have a selection in various watts. Just make sure your headlight housing & wiring can handle greater wattage over the factory design.
