ESP and BAC warning signs

[raycoo]

I own a 2002 CL 500 with 33,000 miles. Recently the signals ESP followed by BAS have appeared in the speedometer display. I reset them, but they reappear at various random intervals like 2 days later or 3 weeks later.
What does it mean and should I be worried about them?

Sounds like the brake light switch.

Yup !! Eventually when the sensor get worse, it will come on every time when you on the brake after you start the engine.
