All "check" lights come on briefly when starting your engine. This is to make sure the light is working if soemthing does malfunction on your vehicle. If the light comes on while driving you may have broken or loose belts.

If the battery light comes on briefly after starting but then goes off, it could indicate a temporary drop in voltage while starting the engine. It's a common occurrence and not necessarily a cause for concern. However, you can still have the battery and charging system checked to ensure everything is in good working condition.

Do you have a diagram on 9volt battery and light bulb?

I can't display images. However, a 9-volt battery can be connected to a light bulb by attaching one end of a wire to the positive terminal of the battery, and the other end to the bottom tip of the bulb.
