I had yellow city lights back in 94-95 and I was pulled over for tint after sunset. Well he was in the middle of an intersection and spotted my car with yellow lights so he waited for me at the next intersection, I'm sure I wasn't pulled over just for the tint because the light was the second thing he checked after noting my light tint. (I said I got the tint with the car). He didn't see that the lenses were yellow so he let that one go. He let me go on the tint with a warning.
Oh, that was in Glendale too.
Bottom line is, it draws attention. I run regular white city lights now and haven't been hassled again since.
