I thnk the only fasteners they didn't use were some reed and prince metric screws!
Anyway, I was trying to post a video.its not bleed over from another light because it happens about 1/2 a second after the other lights come on. Maybe the video camera is not fast enough to show that.
Also, removing the the turn relay causes the indicator light to be off, and the other light are on.
I cleaned all the contacts and checked the transparency printed circuit board for little like. Didn't see any. Cut with an exacto a couple of suspect spots.
I have a great idea!! Let's just print the circuit onto film!
