On my first car the mechanism that is supposed to adjust the headlight level was broken so the lights "fell" into their lowest position so only the front of my car was lit up. On my second car i took the time to fix everything and adjusted the headlights to a correct position but the bulbs themselves were old and probably had weaker or less brightness than new halogen bulbs. As far as LED bulbs, i only use LEDs in my high beams. I don't want to be that guy who blinds everyone with their cheap LEDs but with high beams you're supposed to switch them off anyway. Doesn't really make much of a difference to me if you use LED high beams or if you add a LED Bar (so extra lights) to your car. LED high beams just don't add an ugly extra lights to your car while also being a bit weaker, so if you forget or drive on a windy road then you don't blind others as much.
