So the newest adventure of owning an MKS is while driving the drivers headlight will turn off, when I cycle the headlight switch off then on to automatic the headlight will turn on again. Sometimes it happens often sometimes once or twice while driving at night. So what parts should I check or test first?
Also passenger headlight is showing condensation in the lens, is it possible to reseal these headlights?
Do the head lights turn off in manual mode ? If they dont then its something to do with the light sensor.

Well only the drivers headlight turns off, but I will test in manual mode tonight
The drivers headlight shuts off in manual mode as well.

I have this exact same in my 2011 SHO. Been dealing with it for quite some time too. It

Any idea of what the cause could be?
None whatsoever ever. Looked over fuses, done all the basic stuff troubleshooting and didn
have you replaced the bulbs or are they original to the vehicle? sometimes condensation is caused simply by an improperly seated bulb or dust cap. dry it out with a hair dryer first, make sure bulb and cap are properly seated, then reevaluate.
MKS comes with HID standard I think. if so, the ballast could be failing, or the headlamp switch/FLM could be. each bulb is fused separately at 20A and likely is in the engine compartment fuse box (BJB). (Fusions have them in the passenger compartment lol.) IME, fuses rarely blow, most times they need reseating. unless there is an external force like water, rust, dirt, etc.
one other possibility is the shutter inside the headlamp that switches high to low/vice versa. might not be working correctly. make sure it is activating when commanded. do see these fail from time to time.
if you need a used headlamp, check ebay or car-part.com.
Thank you Shodded
