Range Rover headlight won’t come on all the time

I’ve owned multiple Range Rover models over the years, and let’s just say, I’ve experienced my fair share of “quirks” that come along with owning one.

I mean, who doesn’t love when their luxury SUV experiences electrical issues and won’t start? So when I was asked to write an article about the Range Rover headlight not coming on all the time, I wasn’t surprised.
