Unless the tinting is so dark as to be opaque-to-eye (not so opaque as to let no light through when the light is on - just the type of opaque that is "off-road/show use only"), it's going to have little effect on police LIDAR.
Yes, to a degree, light is light, and your IR reflectivity will be cut-down with *any* tinting.....but that's also the problem - that police LIDAR is IR-based, and although your cosmetic tinting may visibly darken your light's appearance to the naked-eye, to the receiver optics on the police LIDAR device, that it may not appear so "dark" at all.
And that's where items like the LaserShield and VEIL come in.
These devices, although appearing to be "transparent" actually significantly attenuate IR. Visible proof of this exists from various members on the RadarDetector.net Forums, and I'll snag the pertinent posts to add here, tomorrow.
So unless your ride is equipped with such "visually opaque" covers/tints - such as those made by AVS, etc. (where their effectiveness has been proven, by the likes of the over-the-top, die-hard enthusiast alpinestars
, on his various vehicles - really, you're better-off, in terms of IR coverage and the semblance of road-legality, with VEIL.
Is the Veil darkening the lens 'or' lessening the shineyness of the headlamp?
Yes to both.
G4, the current VEIL formulation, is leaps-and-bounds better than the outgoing G2, in terms of optical transparency. One light coat will barely diminish your light's output.
With coventional halogen-incandescent lighting, a slight step up - say, a 10 (ten) Watt overwattage application, will render the resultant single-G4-coated lighting to be somewhere between the OEM's brightness and that of the slight overwattage solution's. With OEM or aftermarket HIDs, the difference is all but un-noticeable.
Slight blurring of the cut-off line should also be expected, but depending on your headlight optics, this may or may not even be noticeable.
In terms of aesthetics, yes, your headlights will appear somewhat "dusted."
G4 is nowhere near as "dirty" appearing as G2, but I still would say that show-car owners should shy away from it. For an everyday-driven road-car, even an overnight's stay in your garage will put enough dust on the lens that it'll make the VEIL seem un-noticeable.
My vehicle is blue - and VEIL G4, as it turns out, is also somewhat "blue" appearing, when applied as a light, single, coat: Veil G4 Sneak Peek (PICs)
With just a single day on-road or in the garage, my application looks, from anything farther than about 10 ft. out, to be a very light tint over the lens.
But again, closer inspection will see fault, which is why I cannot recommend VEIL for true show-car owners.
Can Veil be used on a tinted headlamp w/o destroying the film?
Multiple users of VEIL have presented their cases (as well as experiments) with such aesthetic as well as protective film overlays to the RadarDetector.net community - so far, none have been successful, and all have resulted in some degree of aesthetically unacceptable or even damage-inducing scenarios.
I will again return here tomorrow, with posts from RD.net, to support this assertion, but rest-assured that, for the time being, this is definitely not something that's recommended.
