Nope. One side should be enough.
You did connect the resistors in across the LED's didn't you. The supply from the relay should connect to the +ve end of the LED array and the resistor. The other end of the resistor and the LED go to ground.

However, the flash rate is still fast.
Do I need to have all 4 indicators and resistors in before the flash rate will drop?  |
