My guess would be this. The wires are reverse for the functions you want. They probably have a resistor in them so they have a bright side and a dime side. Since it is backwards of your system you get a blink on the dim side when the park light is off, but when you turn the park light on you have full voltage making them constant bright. Therefore you see no blink. Now the only way to know for a fact is flip your wires around but that probably requires cutting them and in my .02 not worth the trouble caus they are not very good or bright any how. The dim side should be constant on with park. Then when you hit turn you get full voltage and the light gets brighter causing a noticeable blink.
