How do you check the ignition bulb?

To check the ignition bulb, first, ensure the vehicle is off and disconnect the ignition switch or battery for safety. Remove the bulb from its socket and inspect it for any visible signs of damage, such as a broken filament or blackened glass. You can test the bulb by connecting it to a power source or using a multimeter to measure continuity. If the bulb illuminates or shows continuity, it’s functioning; if not, it needs to be replaced.
