Aftermarket blinker controller to fix LED Hyperflash?
2003 GMC Savana, put in all LED blinkers and now I have hyperflash which doesn't really bother me but I'm curious is anyone has found an after market replacement for the GM 25746427 light controller that will resolve it. The original part goes between $60-$120 as I've seen it so I wonder if it's worth bothering with.
I think I found what I'm looking for, the NOVITA LM502:

It's currently going for $50.79 on Rockauto (for reference)
