Typical SCCA lack of rational thought.
Easy answer:
Have the SCCA do a test or two on various lights. Using a pretty cheap lumen detector.
Come up with a list of acceptable lights.
Make sure the max cost is no more than X dollars as a criteria for approved lights. AND keep that number low. Say $50 max!!
Why does the SCCA always do things the hard way?? Is there no one there on the FSRAC or BOD with any common sense?
Just adopting FIA standards shows a lack of effort and laziness on the SCCA. Why not actually do some work and research before you all adopt a rule?
Do not all classes need to be just as safe???
On that same thought what about GT, touring, prod and IT classes. Should not they be as safe as the formula cars and sports racers.
I wonder if anyone has had a collision because they could not see the rain light in front of them
