I wonder if maybe you just intentionally avoid the issue with your clients because if they ever ask they won't like the anwer you give them...
Probably won't make a difference to a customer driving a Lexus or a Beemer.
OTOH, if I see a couple of hybrid cars and/ or solar panels on the roof, they're usually a good target for LEDs, no matter where they're made.
