The answer to 'why is my recessed lighting' is that there can be several common causes, including a blown bulb, faulty wiring, or a problem with the recessed light fixture itself. Symptoms may include the light not turning on, flickering, or the bulb burning out quickly.
Some potential solutions include replacing the bulb, checking the connections and wiring, or troubleshooting the light fixture. For more complex issues, it's often best to call in a professional electrician to diagnose and repair the problem safely.
