Why does the warning light for faulty light stay on even after changing the bulb?

The warning light for a faulty light may stay on even after changing the bulb due to a few potential issues. It could be caused by a faulty socket or wiring that isn't making a proper connection. Additionally, some vehicles have a system that requires a reset after a bulb replacement, or there might be an issue with the vehicle's computer system not recognizing the new bulb. It's advisable to check these components or consult a professional if the warning light persists.
