What is the location of check engine light

I'm sorry, this question isn't making much sense. You are asking to replace a bulb for the check engine light, but you don't know where it is located? The check engine light is located in the instrument cluster. If you're not aware of how to access this or make repairs, or don't even know where it is or if it's working, I would recommend a professional address the concern.
