I had wondered whether the brake actuator pole would work for the brake lights.
thanks!

Trailer brake circuits are 12-volts, because it powers the brake actuator magnets (Or sometimes a hydraulic actuator), so most of them supply up to 30 amps. So yes, they power lights fine but with incandescent, you have to have the brake controller voltage maxed out.
One thing I've noticed is my controller doesn't say a trailer is connected which it's only the hitch rack, but it still works!
