DIY headlight bulb replacement should be banned. You ought to have to

Changing a bulb for one of the correct type won't alter the beam setting.
What is more likely is the car has been damaged and repaired and the new
unit not adjusted correctly. If a new car, this won't be picked up until
the first MOT.


When was the last time you changed a headlight bulb Dave ? They have offset
locating 'tangs' on them to make sure that the main and dip filaments are
correctly located in the reflector. Unfortunately, many modern headlamp
units are so awkwardly located that bulb replacement can only be carried out
by feel. In these cases, it is perfectly possible to get the bulb in place
such that at least one of the locating tangs is not in its slot. Because the
retaining clip is only made of a thin gauge spring steel wire, it is
vanishingly easy to force it back into its clip, thus holding the bulb in
its seat at an angle. The result of this is a beam pointing either at the
ditch, or the moon ...
