On my 2012 they have never given me any errors or codes. The center high mount brake light caused a stored code about the circuit being open but it's only visible with a scan tool, nothing annoying on the dash. Your 2015 may be a little more picky about exterior lighting but Recon is a reputable company and I'm fairly certain their stuff is well tested. They list two sets of lights, one is for trucks that came with LED, the other is for trucks with incandescent lamps which will have resistors included.
