Chuck, mine are also like that. I asked River Park why the Xite control head bottom row of buttons only illuminated with the headlight switch on. Their response was Entegra must have tapped into the light source. The buttons are illuminated on the unit they have on the bench at River Park, power on and off.
Maybe that's the power source they used for the Entegra logo screen when the unit is off???
