Just bought a 2011 mountain air and the coach battery's and chassis battery's go dn owner night why, the light switchs stay lite with a dim blue light all times I don't no if there is away to cut them...
Have the batteries tested - it's free at almost every tire/auto parts house. The led lights your looking at consume nominal battery power and won't have any meaningful impact overnight on your batteries. It't likely that you have an issue with your batteries +/or something related to their charging.
