assuming you mean the check engine light, or the picture of the engine.

That is commonly known as the "Check Engine" light. The light is on because the vehicle's on board diagnostics as detected a problem. Have a trusted mechanic take a look at it soon. If the "Check Engine" light ever flashes while you're driving, stop the car when it is safe to do so and shut off the engine immediately.
