So many garages set the lights way too low. This has been a problem all my lifetime, I remember fighting with the beam setter equipment back in the early seventies.
If the garage ha reset the lights, and the owner then can't see ahead at night, they might raise the lights again, for it to fail again the following year.
Or.
The lights have an electric motor to adjust beam height to compensate for loads in the boot. The reflector inside the lamp sits and pivots on studs with a ball and socket arrangement to hold the reflector. Sometimes these pop off, then the reflector can move around.
They're a real pig to pop back on. have to remove the bulb, put hands into bulb hole, hopefully protected with a clean soft cloth, and pull the reflector hard onto the ball.
So have a good look at the headlamps. If unsure, try to move the bulb from behind, if it moves, the reflector has popped off.
