Drewhop Posted June 11, 2010 Report Share Posted June 11, 2010 Wiring up a 4 wire turn signal system. using same bulb on a Rat Rod. Essentially If the turn signal is on the light will flash. If the brake is applied it will brighten up and still flash correct? It should be simple is there something I am missing. If I need to explain it better let me know.
