I have LED tails, which mean LED flashers in the rear. I had the hyper flash problem, and didn't want to deal with resistors and heat and what-not. What I did was go to Walmart, get two $3 trailer lights, and attached them under the truck, and added them to the blinker wiring. If you cover it with tape, the light won't be visible (I didn't cover mine) I have one mounted neatly on each side, under the vehicle, spliced only into the blinker wire for each side. Works like a charm.
