For Christmas my dad got me 4 Blue Tire valve lights. I mean, it looks pretty cool... Only supposted to work when its dark and in motion, but I dunno about this.. Kinda Ricey. I said "Um, gee. thanks Dad" He said "well if you don't like them I'll put them on the Bronco" My question, are they illegal in TN? I was all excited about the Stereo and speakers, but these tire valve lights... hmmm..
