while driving home tonight my brake, park brake, battery, and service lights all came on at the same time. They aren't bright like my washer fluid(not a problem just need to add fluid) one is they are dim and kinda fluctuate brightness but never get really bright. What's wrong?

Sounds like a charging system problem. All the affected systems have computers involved, and computers do weird things when they try to work on low voltage.
