I was due for inspection this month so I went to my local mom & pops to have it done. The guy almost failed my truck because of the tinted tails. He said the reflector cannot be covered in tint and that the lights had to be red even when not illuminated.
I only passed because he had already entered the new sticker information into the computer and the lense had the D.O.T. on them (of course, these were just stock lenses with the VHT spray on them).
Just FYI for you other Texans out there!
