Rerofitted Led Tail Lights, Now have no blinker, or brake.

LED bulbs draw less current, which is why people like them.

The "blinker" relay is a typically a very old fashioned bimetal thermal switch. When it heats up (from current running through them). This is why when either the front of the back bulb is burned out, they blink fast.

Adding resistors defeats the goal of less current draw.

What you want is an electronic flasher relay. (Google is your friend). Flash the same speed all the time, which means your won't know if you have a non-functioning LED turn signal.
