GS100A brake light modulator

[Beebop]

I'm going to add a secondary brake light on my Dakar, probably
on the back of the top box, and use the GS100A modulator on
it, just to attract more attention from inattentive drivers.
Does anyone know if this is legal in SA?
I dont really want to attract the attention of the local constabulary
if at all possible.
Also has anyone tried it on canbus? The interwebs are inconsistant
on whether or not it works on there, as I'd like it on my RS too.
