I cant remember offhand what model, but I cut open the headlight sensor wire, dropped in a toggle switch, any spst (single pull, single throw) should do, I guess you could get fancy and put a lighted one in there, but I didnt bother measuring the voltage on that line, but I assume there is probably enough voltage for a lighted LED toggle, so when the sensor is "on" via the switch the light in the toggle is on. But you could wire it up any darn way you wanted to.

Perhaps this following little addition could go into the wish list, but I am unsure of the display properties of the unit, perhaps you could wire the dimmer into the dash illumination potentiometer and select the brightness of the unit, along with the dash lights?

But I agree, at night a nice little light show is cool to show off, and with my windows being tinted, the display has to be pretty bright at night for others to oooo and ahhh.

36Gb wont be enough soon!!
