NO! People prefer to upgrade to projector style headlights for a more uniform and even light output, that doesn't blind people. However, you still can use HIDS in standard type headlight housings. The trick is aiming them correctly. You might have to aim them down a bit more, and they may not be as perfect and uniform, but they still are going to provide you excellent lighting performance if aimed and used correctly. Projector headlight housings are better, but sometimes a person cannot afford projectors. Or sometimes a projector type headlight housing does not meet the persons taste or likes as far as look.
