Came across this via rennlist, but I'd always thought it strange that the headlamp knob never had illumination like the other knobs, ( fogs, heated window etc). I had a look in the Porsche PET at the knob and it didn't show a bulb in there...BUT THERE IS!
It's a regular 1.2 watt push fit bulb, and it comes on as soon as the ignition switch is on, so I guess it is the first bulb to burn out...very simple job to replace if your interested, gently remove the plastic part that has the headlamp symbol on it, called the legend in the parts catologue, the get some needle nose pliers with some duct tape round them (that helps grip the bulb) and gently pull it out. Simply push the new bulb in and replace the legend. Job Done! Just replaced mine took 3 minutes.
