2006 Infiniti QX 56 Left side Head light Not Working but bulb is ok

[Kpurrr]

The 2006 Infiniti QX56 has a problem with the left-side headlight, which is currently not functioning. Upon inspection, it has been confirmed that the bulb is in good condition and does not require replacement.

It has been checked for faulty headlight socket, damaged wiring, or a blown fuse in the electrical system. None of those proved to be of concern. Any inputs?
