And another................possibly for MOT tester types or Police traffic Trying not to add loads of extra switches to the dashboard, the existing light master switch on the dash has two positions,1- lights, 2-lights and dash illumination. Thought of using this switch to provide 1-rear fog light, 2- rear and front fog lights. Then using an ignition controlled relay to send power to the column light switch.Is it a legal requirement to have sidelights useable with ignition off? Front fogs are not a necessity, so if this is not doable, I will forget them. I am aware that on roads over 30MPH, you are required to park at night with side lights on, so to meet that requirement [ like never !] I could just leave the ignition on.
