For anyone who's lowered, you won't have failed to notice that the headlight beam seems shorter and allows you to see less up ahead
Obviously, due to the car being lower, the lights are lower too. So the beam isn't shining so far ahead as it's now lower to the ground
Due to all xenon having auto-levelling systems, it's not possible to amend this
However, I've come across these from Cusco

Ordered a set and will report back once they arrive
