Anyone have a LED tailgate bar?

[Mayo]

I bought a 60" Recon White Lightning for my truck back at the end of July but never hooked it up. Yesterday, I got my trailer wiring harness from LMC so I installed that and figured I would test out the LED bar. Everything works, the running lights, turn signals, brake lights, but I didn't wire up the reverse lights. It looks good, the only thing is the brake lights and turn signals are barely brighter than the running lights. Has anyone had this problem? Is there something wrong with my truck or do you think the light bar might be defective? Thanks.
