Discard the light bulb properly.

Why is my Fog light not working after replacement?

If your headlight bulb is not working after replacement, it could be due to incorrect installation, a faulty bulb, a blown fuse, damaged wiring, or a defective socket connection. Double-check the structure and connections to ensure everything is properly aligned and connected. If the issue persists, consider testing the bulb in another socket or checking the fuse and wiring.

Can I use a different size and wattage of headlight bulbs?

It’s recommended to use headlight bulbs that match the size and wattage specified for your vehicle in the owner’s manual. Using a different size or wattage can affect the headlights’ brightness, visibility, and overall performance. It may also overload the electrical system or cause excessive heat, potentially damaging the headlight housing. Always adhere to the manufacturer’s recommendations for safe and optimal headlight performance.

Replacing the fog light/day running light on a Mazda 3 can be difficult, considering that you must reach behind the front bumper to get to the bulb and replace it.
