I say "Fog" because we always called these "Driving" lights. Fog lights are amber, where driving lights are clear. Reason being, if you turn on more white lights in the fog you're going to get blinded, amber lights will cut through the fog. These are the factory lights with the factory switch.
Anyhoo...it turns out that, as usual i'm finding, it was the switch. It was all gummed up and yucky. Took it apart, cleaned it up, put on some dielectric grease and popped it back in. Working great! At first the switch light was also coming on, but it's not now, i'll work on that. The problem is, there is power to the switch at all times, which means the lights could accidentally get left on easily. I can't imagine that this is how it is supposed to be. Normally, at least here in the US, driving lights only have power when the headlights are on. I actually prefer mine to come on with just the parking lights on, nice to have just the driving and parking lights on sometimes when it's not dark enough for the headlights. Is it possible this switch was rewired at some point? There is no sign of this with just the switch panel pulled out, so I will get the top of the dash off to look further.
My main question is, what is the normal operation for these, ON with parking lights, or ON with headlights? Also, if I attach the power supply to the parking lights, will that put too much strain on that circuit?
Thanks!
