The flasher circuit now has a much smaller load on it then before. Years ago you needed to swap out the flasher in the truck for one that was compatible with LED lights. I'd look into that. I don't know if you can change them out on the new trucks.
One way to get around that was to wire a regular bulb in parallel with the LED lights so there was more current draw. This will make the flasher circuit work properly again. The problem is this kind of defeats the point of putting in LED's if you're trying to reduce current consumption. You still get the longevity and cool look of LEDs.
You can buy the resistors as dummy loads that increase current low load demand that LEDS are designed for. Flashers are still manufactured the way they were 100 years ago. These flashers cause the contact to make and break through a bimetal pathway--causing the blinking depending on the electricity that is going through it. Look on ebay. They sell hundreds of them. LEDs are great but they are not "plug and play". In some applications,they could act weird and even affect other electronics. Consumers should have been made aware of this but they didn't. A lot of them are not DOT approved.
