This thread started out on the Landing Light thread in the RV-14 Forum. I stated:
"I see everyone using different makes and types of nav and landing lights for our RVs, but according to 91.205 to be legal for night or IFR flights don't we have to use TSO'd lights?"
BobTurner came back with:
The FAR actually says "approved" lights. Most interpret that to mean a light that meets the FAA's specifications (brightness, angular coverage, color, etc) but not necessarily TSO'd. It is clear that Christmas tree bulbs are not "approved"!
This is for nav and anti-collision lighting. There is no requirement for landing lights, at all. You do not even need to have them, if you so choose.
I had just read Mel Asberry's article (Ask the DAR) in Kitplanes (August 2017) in which his quote was:
Your operating limitations state that to be approved for night and/or IFR flight, the aircraft must meet the requirements of 91.205. Since 91.205 is written primarily for standard certified aircraft, there is no mention of "lesser" requirements for Experimental aircraft. Therefore, to meet the requirements for 91.205, the aircraft must meet the same requirements as if it were a standard certified aircraft.
It didn't say "specifications" as Bob had mentioned, it mentioned "requirements".
Landing lights aside, I just wanting to see what most of Vansairforce had to say about this.
