Service AFL Lamp Warning

[somebody]

My front left headlight went out. My Service AFL Lamp warning came on immediately. A few days later my Check Left Low Beam Lamp warning came on. I replaced the bulb and it didn't work. I checked my fuses; everything looked good. I noticed some condensation in the headlight after a day of rain. Any advice? What can I do next? Anyone else have this problem?

Interesting...... as noted condensation doesn’t mean water leakage. Different temps, humidity difference a good cause. Wouldn’t worry too much about enclosure, lamps are no longer halogen as another set of rules there.

As anything like that a good Mechanical connection is required for good electrical contact. Check lamp(s) electrical contacts as humidity can lead to corrosion or perhaps intermittent condition. Always look for the least evasive problems first, yup been there done that too lol.

This may help but it is on the 2010-11 model year and you didn't mention what year. Also you can check the Cadillac SRX fourm which also has the same issue.

I have the same problem with my 2016 Buick Cascada premium. Service AFL headlight then a few days later " check right low beam light" came on. Bought new bulbs and installed it. Came on briefly, then went right back off.

Yep, I'm experiencing the exact same issues. Although the headlights are working but the service right low beam headlight and service afl headlight warning is still lit up. I have no idea how to get them off. However, I had to replace the ballast a couple of times already but the service light has never went off. Also, I have noticed condensation in the headlight assembly. I cannot find why there is moisture getting in the headlight assembly. Everything appears to be sealed up good, but obviously, is not!
