I've had my 3g TL for about 4 months now. Haven't had to do a whole lot of night driving until recently now that it gets dark earlier, but I've noticed that occasionally while driving, my fog lights will flicker off for an instant and come back on. I can hear the clicking sound that they make when they are turned off and on (like a relay sound), as well as the indicator light on the dash goes off when they flicker off, like it's actually being switched off then back on. It's both lights at the same time. My high beams also do the same thing in the exact same manner, including the indicator light going off then back on. It's only for an instant, and doesn't seem to necessarily coincide with hitting bumps in the roads, but it could be small changes that I'm not noticing as well. Since these are both controlled by the turn signal stalk, does this seem like maybe the stalk is going bad and is in need of replacement?
