No idea what "RN" on dash is for, no it's not for nurse

[Coria]

I am new to this forum, but thought this might be a good place to start. We just bought a new to us 1998 Dodge Islander with less than 30,000 K's and in mint condition. The previous owner didn't know what the RN toggle on the dash does. Any ideas from anyone. There's 2 toggles, one is BK which is for the back up lights, but no idea on the RN. We know it will use battery if it's left on. And it's not for rear noise. Would love to figure this out.
Thanks,

Perhaps "Running Lights" which are the parking lights. Switch it on and check the front and back lights.

I believe we checked that as we too thought that made sense considering the BK beside it was lights, but will check again. Thanks.
