One of our newest categories, color changing halos and demon eyes are among the most popular additions recently for cars, trucks, and motorcycles! Adjust the accent color of your headlights from a remote or even your phone with bluetooth technology! We define demon eyes as an active light inside a projector that gives a soft glow, not quite as bright as the light source of the projector itself and its primary purpose. Demon eyes do not impede or reduce the performance of the projector, and generally are not visible during the day, they're not that bright. With our RGB optional demon eyes, you can set the color of the projector back-lighting aka demon eyes to any color you choose.
