Interesting 16V thought: knock light LED?

I got to do that to my Saab! Where did you see the article on it? (assuming there is one?) I think my knock sensor is on it's way out, as the car isn't producing nearly as much boost as it should before blowoff. Not that it's producing anything at the moment but for future reference it sounds quite useful.

Very, very interesting indeed: This was standard equipment on my Mom's
1987 Peugeot 505 STX V6. Peugeot put a little yellow LED at the base of
the instrument cluster that would flicker when the car sensed knock.
In our case, the thing flickered all the time prompting the dealership to
call it a bullshit gimmick and disconnecting the LED.
But since then, I've always thought it'd be cool to have one! :)
