I just got my headlights and taillights tinted by Victor with Invisible Edge (phone 951-833-1914).
The headlights have a light tint that isn't as obvious in pictures, but are pretty obvious in person. They are not very dark, but that's completely fine with me as I don't want to limit visibility very much.
The taillights are just one shade darker than the headlights, but are much darker than I originally expected. Hopefully I will have the LEDs delivered tomorrow so I can install them in the coming days.
