I have a set that came with those exact pieces, & another set without. The first set that I got didn't have them, & I had to wire in some resistors. When I installed the second set with the boxes, I removed the resistors, thinking I didn't need them. Well, I did. Hyperflash. Had to replace the resistors. But I also have LED tails, & corners, so that could be the cause of the hyperflashing. Don't really know. I'm no electrical whiz, but they work, so that's all that matters.
