The headlights are failing. They are very dim. I am no longer driving this car at night if I can avoid it. If I do drive at night, I have to have the brights on 100% of the time to see the road effectively. It became more serious 2 nights ago when I could not see a median in the road and ran over it. I had three teens in the car with me. I had driven as a chaperone to a school competition. We were at the beginning of a 4 hour drive home in the rain. I have not taking any action to repair or replace anything at this time. There are no vehicle warnings to indicate the problem.
