  2. Remove the Bulb: Gently pull the bulb out of the socket. If it’s stuck, wiggle it gently to loosen it.

Step 4: Inspect the Bulb and Socket

  1. Check the Bulb: Look for a broken filament or dark spots inside the bulb. If it’s burned out, it needs to be replaced.
  2. Inspect the Socket: Look for corrosion or damage. Clean the socket with electrical contact cleaner if needed.
