change light bulb running light (front) next to large headlight

What is your question?

I cannot figure out how to change this light bulb? It is the smaller light next to the big head light. I took off the plastic cover. I see a black plastic knob so I unscrewed it but it does not want to come out. It looks like it is connected at the front by wires. Can you explain how to remove this light bulb to install a replacement bulb. Looks easy but I hate to pay to have a mechanic replace a light bulb. Thanks
