Left: Stock amber 1157 bulb
Right: V-LEDs Switchback (Type 2)
Blinker mode:
Type 2: Amber-No Light.
Type 1: Amber-White
I found that type 2 would be better. For Type1 bulbs, The Amber light is not easily distinguished from the white light. Infact the Amber color seems to be not as bright as the white light.
