That looks very cool, I am a bit scared of making holes in
metal cases, though. Even with plastic this can be complicated
enough, if you don't have any special tools.

Actually I think I will connect another LED and use a non-transparent

bright that it is distracting at night. I suppose connecting 
another "normal" red LED to the PPS output cant' be a problem.
