With incandescent bulbs to LED 6 OHMS always did the trick The flatbed has LED turn, brake and tail lights. I am having a hard time satisfying the body control model to make the blinkers blink correctly. Has anyone had this type of problem???
The factory lights might have resistors in them so the BCM can be used with led or incandescent. I'd test current draw of both the factory lights and the flatbed leds to see if they're significantly different. Then if the flatbed is lower add resistors to get it about the same as factory.
Also take a look in the BCM to see if it's set any blown lamp codes. They might need cleared to get the blinkers working normally.

Correct me if I'm wrong...

It would be better to check the OE rears so that you're comparing apples to apples. Though I was assuming Paul was the one who switched the beds and would have the OE lamps available.
If the front turns are LED checking them would be better than nothing. If they pull a couple amps they've got resistors to mimic incandescents. That would strongly suggest the rears would be similar but wouldn't guarantee it.
