Headlamp repeatedly burning out

Still loving my 2004 TL but am having funky issue with headlamps burning out. First one burned out around 100,000 and assumed that was normal. Then the replacement burned out around 130,000 (2-3 months ago) and replaced it then. Now today that replacement just burned out. No obvious problem with water inside headlight enclosure. Could it be the control unit or the igniter?

Swap the bulb from side to side and make sure that it's not the bulb that is bad. It could be a bad connection to the ignitor or ballast. You can swap 1 part at a time from side to side to figure out the culprit.
