Ok quick one should the interior clock backlight come on when the ignition is on? from what I can remember of my orion years ago which had the same clock the backlight only came on when sidelights or more were on?

Also for some reason sidelights work fine until ignition is on, then the headlight bulbs illuminate very dimmly?

So basically looking for confirmation on the correct backlight operation, sidelights or ignition? and any pointers as to why headlights come on with sidelights?

thanks, Lee
