Getnof gave you examples of statutes dictating the height of the aux lights. I won't find the statutes but I know MA, VT, NH, NY, and ME all have that same 42" light rule because I wanted to run my lights during the deer rut but its illegal so it's do at your own risk. That's a pretty common theme with most states. Clearance/marker lights are different and so are emergency vehicles like tow trucksThe fact is, in all States aux lights are legal.. (providing you comply with local regs)
Fact also, most Taxi's are NOT re-purposed police vehicles (really?? now we're projecting tv commercials), they are purchased new, look it up..
FMVSS? you're kidding right?? no one posting on this thread is required to follow FMVSS, those are standards for Vehicle Manufacturers...
So how about lets agree to stop distributing FUD.... (that'd be, Fear-Uncertainty-Doubt)
