Why is my Daytime Running Light Bulb not working after replacement?

Consider several potential factors if your daytime running light bulb is not working after replacement. First, verify that you’ve used the correct bulb type and installed it accurately in the socket, as incorrect installation can prevent proper functionality. Check the fuse related to the daytime running lights, as a tripped or blown fuse could be the culprit; replace any blown fuses with appropriately rated ones. Additionally, inspect the wires and connectors for any damage, disconnection, or poor connections, as these issues can disrupt the electrical flow to the bulb.
