How do you know if the bulb is bad or the igniter on a 2002 acura 3.2?

To determine if the bulb or the igniter is bad on a 2002 Acura 3.2, first check the bulb by replacing it with a known working bulb. If the new bulb doesn’t light up, use a multimeter to test the igniter for continuity and ensure it’s receiving power. If the igniter is faulty, it will need to be replaced; if it’s functioning but the bulb still doesn’t work, the issue likely lies with the bulb itself or its socket. Additionally, inspect the wiring for any signs of damage or corrosion.
