So, I have a 2007 2700BHS pull behind. I purchased a product called rv glow, which basically looks like a relay that you plug into the top two slots of your trailer connector and it will turn on all your running lights while you are stationary. so I just got it in the mail and plugged it in and it didn't work. my thought is that these light are not linked into my electrical system. Anybody else try this product or something similar?
