I think the 07 Tour is nearly identical to my 07 Ellipse and my door handle wasn't equipped with a light.... but I added one.
The handle is made of clear acrylic and lights up nicely. Remove the handle... install the proper bulb (I used a Monaco part)... drill a small hole through the wall behind the handle bracket... tie into the 12v lighter outlet at the copilot's right hand... and install a lighted rocker switch on that same console.
Works like a champ and costs about $15.
An easy job once you get over the idea of drilling a hole in the side of your coach.
Good Luck...
