I have recently got my car back on the road and as an old guy, I guess I have just gotten used to blinkers and don't like not having them. I installed a Painless Wiring Harness so the wiring is there. I also installed an IDIDIT column that has the turn signals switch built into the column. The thing I don't have is a 3rd bulb in my taillights. They work fine for taillights and Brakes. Any ideas how I might add blinkers?
Thanks in advance. Picture of the back of my vehicle.
