Volvo Repair: Hazard light on the dashboard, dashboard lights, hazard light

Question
I have a 850 Wagon with only 34k miles on it. Today I noticed that when I apply brakes - the yellow hazard light on the left side of my dashboard lights up. Brakes work fine. What is this yellow light all about? Thanks, Enver

Answer
yellow light with the bulb inside is that the light you are talking about ? yellow light with bulb warning light is for when you have bulb out/not working  replace both sides brake bulbs in rear   you will maybe  need  also position bulbs but replace  first 2 rear brake bulbs .
