Lighting issue

[doozer78]

I have a 2014 GMC Sierra 1500 allterrain.

I installed a new opt7 triple Red Line LED tailgate bar which has brake running and sequential turn signals built into it along with reverse. Also if you have a rear view camera parking sensors and towing assist you have to buy an adapter box which is just plug and play. The LED bar simply plugs into your 4 flat trailer connector two before installing everything I hooked it up and everything worked perfect installed everything tested again everything working perfect then all of a sudden both my rear turn signals flash rapidly when I use either one. So I disconnected the LED bar in my turn signals continue to flash rapidly now when before it would not been work normal. Alao front signals doing the same Looking for thoughts or suggestions as to what may have happened thanks everyone in advance

Take that adapter box out of the circuit and try again. If I remember correctly that adapter was only needed for the Ferd F150.

I just bought one of those, after one of my coworkers got one. He didn't use any adapter box, and I didn't buy one either? Def try it without!

I don't see any need for any type of adapter, because we are basically tapping into our trailer break lights with this bar.

Hope it works out for you!
