headlight problem

you have to check the healight glasses first if it's not original... if not check the lamp itself it may be put in a wrong way
Semi-obvious first check would be to make sure both housings are equally clean and not fogging up or yellowing. Then, I'd make sure both bulbs are same age (translation: replace both). If issue persists, I'd get a shop to look at it as it might be wiring related?
