Overly complex = unreliable.
When the headlight bulb of my BMW blew, I had to replace it. The headlight assembly is accessed from the front wheel well. To get at it: turn the front wheel, remove a panel, stretch your arm forwards and feel the back of the bulb, undo some screws which you can't see, then remove another panel. The bulb is mounted on another panel which is held in place with some clips. This requires some complicated manoeuvring to get out. Replace the bulb, then reverse the procedure. Unnecessarily complex.
In my old Toyota, just pop the hood and access the headlight assembly from the top.
