I have a 2012 Keystone Outback 250RS that we bought used a couple of years ago. The amber step lights at each entry door no longer work. The bulbs are good. Does anyone know what switch turns them on? How they are wired, like to the porch light switch? Any advice on how to get them working again would be appreciated. I’m brand new to the forum, today! I don’t remember when the lights stopped working or what switch used to turn them on.
