Inspect and Remove Old Bulb

What happens here

With the socket removed, gently pull the bulb straight out from the socket. Inspect the bulb for visual signs of failure, such as a broken filament or a dark, burnt appearance inside the glass, which indicates it has fused. The video shows a clearly 'fried' bulb with a darkened glass. The bulb type is identified as a 7443. **Within the context of 'Brake Light Bulb Inspection using Multimeter':** If the bulb doesn't show obvious signs of failure, a multimeter can be used to test its continuity. Set the multimeter to the continuity or resistance setting (ohms). Touch one probe to the positive contact on the bulb's base and the other probe to the negative contact. A functioning bulb will show a low resistance reading (close to 0 ohms) or beep if it has a continuity function. A faulty bulb will show an open circuit (OL or infinite resistance). You can also test for power at the socket by having an assistant press the brake pedal while you use the multimeter's voltage setting (DC Volts) to check for 12V at the corresponding terminals in the empty socket.

Goal: Carefully pull the old bulb straight out from its socket, observing for signs of failure such as a broken filament or darkened glass. (A multimeter can be used to confirm bulb continuity).
