Changing the tail light

[vincentg]

Hello Yaris World! Im new here and i just got my 07 yaris last month. and it seems the back up light is not working. I already bought the bulb needed through the other thread. And i wanna change it myself (for more bonding experience with the car) any help would do. I already searched the whole forums regarding and there is no step by step process how to put it out.

Thank you guys

UPDATE
now that ive checked the reverse light. i found out that the bulb is in good condition (i switched it to the other side to check if its still working. and it still works just fine) now i need to know how to fix the terminal or how will i find the problem? ive searched tons of PDF files and manuals but nothing to do with the reverse light condition. anyone please do help me.
if i can still fix this or should i call the electrician regarding this.
