I am attempting to make a directional system for a project vehicle. i have 2 rear taillightes, each lite has one 1157 dual elementbulb, i have a brakelight switch and a directional switch and a 2 or 3 prong flasher. i have done a rough install to see of it all works. I can get the low side of each bulb to light ican get the high side to blink on either or the brake lights to both come on but my problem is if i put on the left or right directional on and step on the brakes it stops blinking how do i wire this so when i step on the brakes one side stays bright and the other side remains blinking.
