Is this something you guys are willing to do on a customers car?
Yes, we'll be offering it soon for all customers.
Right, but the HID lens is located behind the blacked-out plastic front, therefore the light output would be significantly reduced because it has to pass through this darker material.
I think you might misunderstand how the Unplugged Performance headlamps are being modified. They have the interior bezel modified, not the clear lens.
The UP headlamps will offered completely upgraded projector assemblies, with custom lenses for noticeably improved output over the OEM Tesla projector. The bezel being painted has does not affect on the output of the headlamp.
Back in my m5 owning days, we would black out the inside part of the headlight, not the plastic cover. That stays clear but everything surrounding the bulb would be blacked out.
There was no way of getting inside those headlights so we had to cut them open.
@bulletproof, are model s headlights easily opened?
Again, I think might have been some confusion, the inner bezel, NOT the clear lens is darkened.
As far as opening the lamps, it's tough to say "easy" versus "difficult" without knowing a person's skill level and confidence. I will say that the MS headlights require a specific process for getting them open cleanly (and without breaking anything).
