I’ve tried both products. Only the Hex does the indicator on/spotlight off option. The Denalli will flash alternately on hazard lights though.
There’s another thread on this to which I contributed further. The Denali has the second “switched live” wire so, it only really works with Denali lights i.e. you lose the ability to alter the brightness via the wonderwheel.
Should also add that the Denali comes with a connector wire which is sufficient to run from the back of the bike to the front (although comes with the three-way connector at the front end to connect to Denali lights). The hex doesn’t come with such a cable (although does include tail connectors to plug into the hex) so, you’ll need to run a +/- wire set from front to back (twice if you want to use two of the channels and use the spotlight off/indicator on option).
