Windshield Wiper Mods

I recently saw an item up for bid on eBay - they were a lighted version of the windshield wiper nozzel that attaches to the front hood of your car. Very cool looking... well, while at Discount Auto Parts the other day, I was talking with someone who had installed these on his car. He stated that he received a $50 fine from the friendly (cough cough) local police who stated that regardless of color (bad blue lights...baaaad) these were unecessary and illegal modifications that would result in repeated fines if he had them illuminated.

Anyone experience similar situations? Granted, I am sure it differs from jurisdiction to jurisdiction, but I thought that was ridiculous.
