Hello and welcome to another one of my how to's. Today we will be installing the Ralliart taillightson the Lancer. Lets get started Tools needed: 10mm Socket Phillips Head Screw Driver Flat Head Screw Driver Some Sort of Cloth First step is to figure out where your taillights are. After you have done this you already won half the battle. Second you will have to open the trunk or this Third take your phillips head screw driver and unscrew these 2 screws. You will need to take your flat head screw driver and cloth and prey it out Fourth remove the bulbs and place them in the new light, and re-install. Fith its time to start on the other light assembly. For this you will need to remove the trunk liner. You will need to take your flat head and pop these out. Sixth take your 10mm socket and remove these 2 bolts. Seventh replace with new taillight Now do the same for the other side Let me tell you these are freckin sweet. They make the car look so much better. Thank you and have a nice day
