odd headlight issue 2014 C7

Today we noticed that one headlight was not working in auto sensing mode. For some reason we decided to switch to manual mode and the headlight came on.

Does the corvette have separate sensors for each headlight or is this some type of electrical/switch issue?

There is only one sensor on top of the dash and it sends a signal to the BCM which then sends a turn on signal to the headlight relay in the underhood electrical center which then connects each headlight fuse with B+ power which turns the lights on. The headlight switch feeds signals to the BCM that let it know which operational mode the lights are in. Choosing manual or automatic doesn't affect the way the lights are turned on by the BCM.

Might be coincidence and the bulb is going out. When mine was going out it would randomly turn on and off when I turned the lights on,off, high beam, etc. maybe you’re just “kick starting it”

On my 16, my bulb failure started with the bulb still working cold. Then when it got warm, it would go out.
