I put mine on the rear shelf inside the vehicle and they point out the rear window. I run the wire thru the interior of the car (it just lays on the seats and floor), open the passenger door and raise the hood and route the cable to the attachment point of the towbar going thru the lower front grill. I had to add about 6' of wire to accomplish this but it works great. They are just as visible in the back window as they would be outside. Never had any problem with law enforcement in any state I've been thru. I also had to screw a couple of pieces of 2 x 6 together and attach a 4" square blank electrical plate to the wood for the lights to magnetically attach to. That's my story and I'm sticking to it. :B
