Welcome from Colorado, Edward. I assume that you are talking about replacing your Willys's Headlights? I have high performance Sylvania Halogen head lights replacing the original head lights. These are more efficient and brighter than most. In addition to them, I also have a couple of "Hella" Offroad Lights mounted up front. If you do any Off Roading, you are likely going to be on the Trail after dark for a ton of reasons. When that Happens, You want to Light up as much as possible all around you, trust me!! Pivnic
