See full version: Troubleshooting Trailer Lights Going Out When the Brakes are Applied After Trailer Light Kit Install
Wired up an Optronics 4-wire system on trailer. All lights come on at startup, then Any turn signal flashes BOTH trailer lights and when I hit the brakes the lights go off. What might I have done? Appreciate any help. here

You also need to make sure the white wire at the trailer coupler is attached to the trailer frame and that the attachment point is free of paint and corrosion.

I spoke with my contact at Tekonsha, who tells me that if the brake controller has been properly installed, the brake controller will have nothing whatsoever to do with the ABS system of your vehicle. If the controller was hardwired into the tow vehicle (as opposed to using a plug-in connector) there's a very slight chance that if the red wire from the brake controller could've been tapped into the wrong circuit. The red wire should be tapped into the circuit coming off the brake stoplight switch that only shows power when the brake pedal is pushed. [links]
I noticed that when I am towing my travel trailer and I hit some rough road surfaces or go over a significant bump on the highway, my ABS and brake warning lights come on. This never happened before I installed this model brake controller. I still have full braking power and when I stop the engine, the warning lights go off. They do not come on when I am not towing. Is it possible I am losing traction momentarily while towing and setting off the sensors? My brakes were just serviced prior to having the controller installed . Is there any adjustments I can or should make to resolve this? I have a new weight distribution anti-sway system on the RV. I am having my mechanic look at my abs sensor as well. Thanks.
If this isn't the case, the ABS and brake warning lights going off are most likely coincidental. I'll link you to our Brake Controller Troubleshooting FAQ article.
To see what can happen when a trailer comes loose, INSIDE EDITION went to the Lancaster National Speedway in Buffalo, New York. Then we did something you should never do -- we removed the pin, undid the safety latch and unhooked the chains from a trailer. Then a professional driver took it for a drive. more
“If they would have hooked that up correctly that day, if they would have put the two chains on and the pin, then right now as I sit here, then Liam would still have his Dad and his sister,” Cox told INSIDE EDITION.
After one person was pulled over and ticketed for having only one safety chain, INSIDE EDITION’s Lisa Guerrero asked the driver, “Did you learn something today?” more
Fix says it’s also important to have two chains hooked up properly. “You have to have two chains. It's really critical, and the key is: you cross them to cradle the hitch in case it comes undone.”
