So today I was just driving with headlights on. When it got darker, I noticed my gauges (RPM, Speedo) were brighter than usual. THEN I noticed none of my inside lights turn on when I have the headlights on. Navi is on but it is on as if I am driving during the day. Gauges are on but again, as if I am driving during the day (really bright). A/C controls, cruise,NONE of the lights turn on. It turns on when I lock/unlock my alarm (aftermarket clifford) but otherwise it stays off. My TAIL LIGHT is ALSO NOT TURNING ON. Again, turns on when I arm the alarm and when I step on the brakes. Even if it was due to my alarm, I've never heard of this problem and why would it all of sudden act weird NOW? I've had it for about two years. Any help would be great

 

Electronics can bug out, and it can happen all of a sudden. I would definitely have a reputable alarm installer check it out... the alarm can affect all of the interior and exterior lights you mentioned in your problem description, plus door locks, windows, and ignition, depending on the alarm's features.

 

i think on the bottom left hand side of ur car there should be a control that you can make it darker and lighter ... i think its by where your knee at.
