This is a small pita, not any major issue , but perhaps someone has the answer. The (center)knob on the combination switch no longer lights up at night as it used to, as is obvious from the "black hole" in the center of the otherwise orange display. I pulled the knob out and replaced the tiny bulb -but no change. The bulb itself checked out OK. The switch seems to work fine otherwise. This too is a good excuse to check out the digital camera....

i have only seen this bulb light up when the knob is pulled out and the fog lights are on, try pulling it gentlyone click out then two with the lights on and see if it works, if you look at it, it has a pictire of a light on it. please let me know how it goes. ray

if you pull the knob gently it turns on the foglights, if you pull it harder the knob comes off and the bulb socket is exposed. Ray

yes, there is a blub inside.... when you turn on the rear fog light..
if u pull once it will turn on the front foglamp, the second will turn on the rear and front fog lamp

hmm I have had the knob off a few times and couldn't find the bulb, I'll look again.

Hmmmm... I only started this thread because I thought that at one time this thing did actually light up .Maybe I am wrong and all along I just imagined it.
carson 356 : Well, in my car , when the knob is pulled (toward driver) only the center orange dot thingy lights up (Not the white arrow or light symbol ). When pulling you feel a spring type resistance rather than a klick.When you release it, it snaps back into place.
If you turn the knob left it activate the parking lights as it should.Still - the knob stays dark.
Hatterasguy : perhaps in your car the lamp is missing. It is the tiny mb type lamp sitting in the center of the metal tube that holds the Knob.You just pull it out.

Thanks guys. I realize this combination light switch is somewhat more complex than breakfast cereal, so perhaps on mine some of these functions are just lost in time and I need to live with that.
