Hardware: 9500CI - ZR4 Rear Head (culprit)...
About a week ago I got pulled over after being followed for a good 3 / 4 of a mile. Long story short, the officer was a nice guy, but the 'warning' he gave me was for inadequate lighting of my rear license plate.
I assessed the situation, and the entire traffic stop is / was bullshat. You can see my plate just fine in the darkest of conditions, BUT because the ZR4 head is there it gave them a reason to pull me over.
So my advice would be just to check yours out when you get a chance and if it looks a little dim you might have to move the light over a touch. or make it off center.
