To clarify a recent change to general MSA regulations:
A car running to current regulations published by the Clubmans Register does NOT require brake lights regardless of the event it is entered in. This applies to all Clubmans formulae events - not just Clubmans Register sanctioned ones.
Just to add to Chris' info.
A car does not have to be running in a Clubmans formulae event, it can be running in any event,(i.e. the regulations for that event allow Clubmans cars to enter), but as long as it is running as a Clubmans Formula car under CURRENT Clubmans Register regulations, then it does not require brake lights.
