Diameter of Vaquero OEM driving lights

[Old Bear]

I finally decided to install the OEM driving lights in the Vaq fairing. I want to put a light tint on them before installing, but I don't know the diameter of the lights. Besides the diameter of the light, I'll take suggestions on tint as well! My Vaq is black, and I want to maintain that look as much as I can. I'm going to black out the assembly, and found one company that makes a glossy smoke tint for headlights. With a headlight-rated tint I should still get good light, more visibility when on, and keep that blacked out front end when off. And finally, this should get rid of that high-speed buffeting that I heard others speak of, which is cleared up by replacing the louvers.
