I am starting a new post.I just put a 5 to 4 wire converter on my trike ,to pull my camper.I am not completely satisfied with how it is working. With the brake lights on and a signal light on,the signal it hard to see.It works good without brakes applied ,or rather brake lights on. I am thinking of going back to 5 wire design and changing the lights on the camper or just adding signal lights to what I have.Any thought?
