2006 BMW X3 Question: warning light looks like sml light bulb??
It means that an exterior lamp (bulb) is defective. I think you are talking about the indicator to the left of the open door light, directly below the airbag light. Pg. 56 of your owners manual. For instructions on replacing bulbs refer to page 99. If you don't have an owners manual, email me and I will send you a link to download one. - BBMW
