If you are referring to the third brake light, I have disassembled them before and they looked like ordinary bulb (albeit, very tiny) and not LED. In fact, the third brake light lights up not as quick as the tail light which is real LED.

But I am not sure if you can replace the bulbs individually.

There is an intermittent rattling sound coming from inside the left front passenger door panel. Any ideas as to what is the cause?

Btw, my PE is still going strong at 160k km. No major repairs, just normal wear and tear parts replaced. All stock, still handles well and speed well.

The only issues are the IAFM (my dad asked me 1 day, why my car is 'purring') and the degradation in steering feedback feel.
