Thank you roxboxxx for the tutorial. It worked.
However, I had a hard time removing the marker light, it was just dumb luck I think I did not break off the upper tab on the light.
So after I managed to change the light bulb on one side I tried the other one, thinking if one light bulb burned out the other one is right behind it.
So trying to do it without removing the side marker light assembly, I tried removing the light bulb socket by removing the headlight assembly first and reach the bulb from that side. It worked, by popping out the light bulb socket with a long, flat head
