Do all the current halo tail light mods on the market need a separate hyperflash adapter for them to flash normally? Are all vendor versions made the same way? Or, is there there a difference between their versions? Is installation plug-n-play and no wiring mods?
Can't speak to all of the halo mod tail lamps, but the set I bought from Radioflyer did not come with nor did they need a hyperflash harness. These lamps include built-in resistors that simulate the load from standard bulbs that is required to make the OEM flasher work at the proper rate.
I think it's the front LED's that tend to need the hyperflash harness. My LED tails from corvettemods also came with built-in resistors. (but I did end up needing a hyperflash harness because I installed front LED's at the same time)
I have had my halos for a few years now, they did not come with an adapter and I needed to add one later. Mine is inline with the halos. Very easy to add. The halos are plug and play. You should be able to change out on your own
The Halo LED tail lights ALL come from the same factory in Taiwan and have a load resistor mounted to the back of each light. MOST of the time, this works to prevent hyperflash, but occasionally a resistor pack will fail resulting in hyperflash.
If you have a Hyperflash Bypass harness, you will never know or need to care if your load resistor is working.

I've had my LED halo taillights on my car for five years and I put the hyper flash harness on the car at the same time. It's not hard to do and I haven't had to worry about hyper flashing even though I have subsequently put other LED lights on the car.
If an LED goes out, does the whole light assembly go out or just the bulb itself? What about options to get something like that repaired?
To my knowledge, we at Radioflyer Innovations are the only company offering electrical repairs to halo LED tail lights. Typically, when an LED or component goes out, it will show up as a row of 4 LEDs. We can also repair more extensive damage up-to and including complete circuit board replacements. (we keep a good amount of parts in our bin) Our repair cost is $65 and decreases on a per-light basis. MUCH less expensive than having to replace the entire set.
It should be noted that we have only seen a handful of these lights needing repairs. For the most part (excluding the load resistors occasionally failing) they are quite reliable.
