High Beam Headlight problem

[I luvRovers]

Hello, I just came home from a mechanic who replaced my PVC valve on my LR4 2016, due to two vacuum codes that were thrown. Anyway, on the way home I was not able to use my high beam lights. The arm switched on but the high beams did not come on, however the flash part of the high beams worked. Everything worked fine last night. Is it possible that a connection was detached when they replaced the PVC valve. To get to the valve, they had to detach many components. Thanks for your help.

I think it may be coincidental.
If I recall correctly, when the bulb is on its last legs, it behaves as you have described.
