– The Retrofit Masters specialize in customizing headlights for better overall performance and looks. Retrofitting headlights involves installing projectors into headlights that originally did not have them. Projectors are the only safe way to use H.I.D. systems in your vehicle. They focus all the light a HID bulb emits onto the road. They have a sharp cutoff that keeps light out of oncoming traffic’s eyes while lighting up the road from side to side for you! While the headlights are opened up, you can opt to customize the interior. This ranges from painting the internals, adding LED lights (halos/angel eyes, LED strips), and many other things!
