that IS a LED flasher that's what we use
it is a two prog flasher
Yes but a semi has a lot more lights/LEDs running so you may still need to run a resistor? Most wiring issue's are a result of bad grounds or dirty power double check both but it seems you know what your talking about..
I had a Toyota Truck that had wiring issue's, lights always burning out, flashers working funky and I went with a ground kit with a power conditioner everyone always thought I had HID's as the head lights were super bright. The fans blew twice as fast, and better gas milage....
Thinking about it might get one for my teener....
