all is normal Phil till you start the engine with the taillights on, and the brake lights come on all by themselves, I spent a couple of hours checking for back feed of power in the car from the light wiring, trailer wiring and electric brake wiring, added their load resistors as recommend by them to make no change, still the same, then sent them a video to them and they agreed their seamed to be an issue but if they bench tested them then their would be no help, I informed them at that point of time that they worked fine on the bench with a constant 12v as I had already done this to validate the lights but as soon as the voltage goes up due to the alternator charging thats when things change, they agreed that if I sent them back then they would exchange them for some other units that may work on my 2003 BA ford ute. Once they received them they called me to tell me they bench tested them and there was nothing wrong with them, dah I said I told your customer service team this before I sent them back, the exchange now turned into for another $140 we can send you the others, ahh hello I just spent $280 plus load resistors for zero outcome, don't think Im about to spend anymore with your crappy company I will just do what everyone else normally does and by the chinese units at half the price.
