When my boyfriend picked up his Jeep Liberty Renegade the dealer told us about the light cover law. He took them off at the dealership before we left. We now have had the Jeep for 6 months and he hasn't gotten told about it yet, but where I live I bet the cops don't even know! I'm gonna tell him to put clear covers on them since it is a grey area teehee.
Also there isnt that much wind noise with his 4 lights, but the jeep does have beefy noises comming from everywhere! I have 2 hella lights from my old WRX that I am going to install on my Baja, but instead of on the crossbar I think I am going to put them on the front bumper.
