Apologies in advance for all those that want me to turn my lights off, but my Chevy Silverado has lights that come on automatically when it is dark and stay on, emergency brake or not. The only way to turn them off is to turn off the truck, which makes it real hard to back down and/or pull out Besides it is a diesel and doesn't like to be turned off and on all the time. I back up real well even in the dark and take all of 10 seconds once in position to get my boat off the trailer and out of the way, so I'm not there for very long, but when I'm there my lights are on, sorry
