Driving in a suburban, part rural town and on the interstate, I see trailers being pulled by trucks and cars that have the brake lights go off when the vehicle’s lights go off. But the trailer doesn’t come with the car or truck when people buy it new, so how can any trailer work with any vehicle that’s hauling it?
I’m a normie, by the way. I’ve never driven a truck, nor ever hauled a trailer, so if my assumption of “any trailer can work with any vehicle” is wrong, please correct me!
Thanks for your answer!
