You are using the wrong filament for the directional lights.
You can’t use the park lighfilament for flashes. They will flash too fast.
You must use dual filament bulbs in the front parking lights. The dimmer,smaller filament for park lights and the brighter filament fo directional lights.
Same in the tail lights, the bright filament has to be brake and directional while the dimmer one will be the tail lights.
