>>>you probably need a few other things by now
Well your information is definitely out of date, TTT, but possibly not in the way you meant!
Legislation requiring motorists to carry ONE breath test kit was introduced in July 2012. (French motoring organisations, and our own AA, recommended carrying two but it was never in the legislation). While that law remains unchanged, the legislation bringing in an €11 penalty for not carrying one has been postponed indefinitely, so you can't be fined for not having one.
French law also requires drivers to carry ONE hi-vis jacket, together with a reflective triangle. (There has never been a requirement to carry a hi-vis jacket for all occupants but, whichever country you're driving in, it's probably sensible to do so).
