How much power do we really need in a tail light?

It doesn’t matter how bright, how many or flashing or still … If she’s staring at her phone when she turns straight into you outside school ( me , 3 weeks ago) it hardly matters …I wasn’t hurt but she ( teacher) tried to blame me until a bunch of honey mummies on school run started kicking off at her …👍
The head teacher (!?) wrote me an apology email …. 🤔

Indeed.

The problem is not one of conspicuity or visibility.

The problem is one of inattention, negligence and downright recklessness on the part of motorists.
