For those who have been following this "engine braking" thread I started, primarily dealing with mechanical questions, part of my real concern throughout has been the associated risk of not flashing brake lights as a warning to following vehicles while concentrating on down-shifting. That issue got discussed in another thread:
Design help for additional brake warning light...please!!
Both in this thread and the other, there has been information/discussion on the possibility of adding a deceleration-activated brake light system which would flash independently of the regular brake light, or at least not require tapping the brake pedal. Several product options were mentioned. After looking them over (Gear Brake, Vololights, Volomod, Admore Smart Brake Light) and checking with the respective manufacturers with regard to their compatibility with my 2017 F3L, I
decided to order myself an Admore. Boy, were they ever quick on delivery! I am going to try installing shortly, and will happily report back with an operational review. I decided, in the interest of additional safety, that anything I could add to the back end that would flash and light up my presence in the face of following drivers would be worth it. I did try looking to see whether any SL sponsor handled something similar, but couldn't find, so went directly to the maker, which has offices both in Canada and the US.
