@Linuxluver do you not use high beams?
You must dip your headlights when following another vehicle, so @Linuxluver is doing the right thing. It's what is required by law.
The vehicle in front should be lit as per the requirements for that vehicle, whatever that may be, but will be something along the lines of red lights that show how wide it is, and probably reflectors as well.
EDIT: Source
You must dip your vehicle's headlights:
- when other vehicles are coming towards you, so that you don't blind the oncoming driver
- when you are following other vehicles
- when you are approaching a police officer who is directing traffic
- when parked.
