How many engineers?

See the mechanic working on my Renault Clio.

Do you know what he’s doing? Looks like he’s trying to squeeze his arm into a tiny space between some metal beams in the engine compartment frame. Why is he doing that? Because he wants to replace a burned out light bulb in the headlamp assembly.

Actually I carry spare lamps in the trunk, so I thought I could change the bulb myself. But after a long struggle I decided to take the car in to a garage shop, in the hope that the mechanic there could solve the riddle: how do you access the headlamp’s back side and extract the lamp?

Why, what’s the problem? Here is the problem:

The headlamp is wedged in behind the tube with the yellow cap, and is practically impossible to reach without disassembling the metal beam behind it. Yep… Renault designed this car so you need to take it apart to change a light bulb.

How many design engineers does it take to make it impossible to unscrew a light bulb?
