OK guys I have a question yesterday I started playing with the wiring on a trailer a friend bought, I should say an old abused trailer, The wiring is somewhat less than, well workable, so its a whole new harness not a big real, but the question came up about mix and matching lights, between LEDs and incandescent light like for turn signals and brake lights. A couple of the fixtures are new but the marker lights are junk. So he doesn't want to spend more than he has to in order to get it road ready. I think I read someplace or some one told me you have to have a balancing resistor between the two so the flashers would work, or something like that. So guys chime in here so I can figure out if he has to go all LEDS or mix and match
