Heard from a friend today that the SCCA will be requiring all formula cars and sports racing cars to have a rain light "meeting FIA Standard 8874-2019, Technical List No. 76" starting January 1, 2024. (See the April 2023 FastTrack). Sounds like a $200 non-optional upgrade to have a blinking rain light instead of a solid rain light.
What was the logic behind this decision? Were there issues specifically related to rain light visibility during one or more of the many recent wet Super Tour events that prompted it?
