Well, the daytime running lights are on whenever the car is running and in gear. They're off when you have the headlights on. So, your service light Doesn't come on when the headlights are on?? If you switch the headlights between on and off (with the car running and in gear) does the service light follow?

Fix My Headlights is a great place to go to correct foggy headlights. They are very trusted and can do a very good job. I do not know anyone who has used it but it seems good.
If your headlights fail and cannot be restored while driving in Arizona, you should safely pull over to the side of the road as soon as it is safe to do so. Turn on your hazard lights to alert other drivers of your situation. If necessary, call for roadside assistance or arrange for a tow to a nearby service station to address the headlight issue. Always ensure you have a plan for nighttime driving to avoid such situations in the future.

Amazon provides this service but there are other less well known companies who also sell these headlights.
