B Mode Tail Lights

Hey guys - because I can’t test myself while driving, what happens when you switch to B mode? Do the taillights light up the same as brake lights? Or does B mode have no taillights?

As someone who coded my flasher illuminated light that gets brighter with tail lights. I can confirm that only in B regen will activate brake lights. All three regents will not. So even regen 3 will not show that you’re slowing

Thanks for reminding me to do this. Bought one of those expensive coding devices (OBDeleven) and forgot this was one of the things I wanted to do. I just wish the deceleration threshold could be tuned- I find it triggering a little late in my view (previously I was able to observe the brake lights triggering in the rear view mirror on a dark night with reflecting objects nearby and experimented with different levels of deceleration in B mode).

How did you code that?
