My TM came with a Pursuit Series Model PRO 9246CH remote system. There are a whole lotta steps, but you can program the system to flash lights when you lock/open the doors/alarm, or do optional events like you suggest (turning on lights).
Pursuit is made by Audiovox. I received an owner's manual with my coach. If you did not, I will copy this and get it to you.
07 TM 40D;ISL 450 Cummins(upgraded). Very happy w/coach
Gnarly toad to scoot around.
