brake light and esp light

I would check my brake reservoir for the correct amount of fluid. If the fluid level was up, I would take it to a shop to get it serviced.

I have the same problem. What does it means? A mechanic told me to ignore it. That the road is just slippery during winter time. I turn off my vehicle and drive again. It will be gone but later on when I do acceleration the break light turns on. Then ESP service shows.
