This was a debate a year or two ago and I did research it some before installing non-tso'd LED navigation lights on my 415C. The consensus of AOPA legal department, EAA, and my mechanic (and my common sense?) was that since none of the original instruments/equipment were TSO'd and the plane was certified that way, then you don't have to replace them with TSO'd equipment. The exceptions are new technology (transponders, ELT's, radar, etc.) that were not a part of the plane at time of certification and now a part of the system. (They don't want to rely on non-tso'd transponders in the system....if they existed.). I did not ask the FAA for a ruling because I didn't want to give them a chance to give a no answer (which might be given with no thought involved and CYA.) Dan C
