Hey Tung
To remove rear light assembly open hatch,on the inside edge of the light assembly you will see 2 small plastic circles with a slot in the bottom pop those off with a small screwdriver and remove the 2 screws underneath then pull the whole assembly STRAIGHT out the back as to not break the plastic pins on the outside.May take a little grunt but should pop right out then you will have access to the bulbs . Change the burnt one and your in buisness
Let me know if this helps Thanks
