I'm not trying to convince anyone either way, just making aware other options
The Hyperlites LEDs look big and bulky compared to the Skene
Recognize that size (number of LEDs) will result in the overall intensity - more elements = more light.
The Hyperlites 3-way have both Stop AND turn in the same package i.e. separate yellow and red LEDs on the same strip.
For the Skene you add another $20 for $145 total which doesn't get you any more lighting capability, just allows the 'stop' lights to flash (programming change only)
If you want compact - and no turns, you can get even cheaper 8-way option from Hyperlites - and configured in either stop only or stop/running.
I can't seem to find informaiton on Hyperlites if their modules are programable like Skene. Such as changing the number of times the rear LED brake lights flash etc...
I would have to question the real need for this - a bit 'gimmicky' and might be fun to play for 5 mins but in the end I would expect most will pick a pattern & stick with it.
But with Hyperlites, they are essentially hard-coded and you first select which mode you want when you purchase
You should note that in various states the flash rate is governed. California especially has its own special requirement.
And whether those rapid flashing emergency turns of the Skene would be legal at all is questionable (in many states flashing lights cannot be misconstrued for actual emergency vehicles)
I did see however that the Hyperlites use a cut wire method on changing
At the end of the day, both systems are microprocessor controlled:
the means of changing the flashing is by setting one of the I/Os high or low which will select different options in the code;
For the most part, Hyperlites take the programming out of your hands and you pick the one you want up front (std brake, modulating, flashing or CA flashing)
and then you get two options for a 5 second cycle or continuous - one is set with the loop connected, the other disconnected. So not variable without cutting or rejoining the wire.
I would ask - how often would one change this after you pick your mode of operation?
The Skene system has an I/O controlled by the brake switch in 'programming mode' - it is doing same thing, setting that I/O in the micro by various input selections, but putting more 'programming' control in the users hands.
So admittedly it has a LOT more programming capability if that is something the user wants/will use. Some might like this capability, others will question its worth.
Also from what I can gather on the Hyperlite instructions is that the LEDs are stick on rather than bolt on.
At the end of the day, once it's actually mounted it's going to be just as reliable - not something that is going to be glaringly obvious and the tape will be secure for what is a very small mechanical load.
But it is another difference to note that may have some value to some vs others.
Just some observations to potentially help others make their selection one way or the other
At the end of the day it will come down to
Cost
Programmability
Mounting
