Yellow light bulb warning light on 2007 BMW X3

A yellow light bulb has illuminated on my dash. Dealership is closed and i can not find out what the light is indicating. Is it safe to drive? Any ideas what it means? Thanks

Simply means you have a bulb blown

With the ignition on, switch on all your lights and check that they all are present and working, have an assistant to check your brake lights

Very common for rear fog light bulbs to bring on the yellow indicator due to a poor contact, removal of inner tailgate trim required and clean and adjust the bulb contact
I have the same light lit up on my 07 X3 3.0 SI ... did you find out what was causing it to light up???
