The tail light lens on your Toyota Highlander sports utility vehicle keeps your tail lights protected. A cracked tail light lens can eventually allow water to get in which, in turn, can cause damage to your tail light and electrical system. The tail light lens of your Toyota Highlander is molded onto the tail light assembly. As a result, the entire tail light assembly will have to be replaced. The tail light assembly can either be purchased straight from your Toyota dealership or ordered at an auto parts store---probably for a cheaper price.
Open the rear hatch of your Toyota Highlander and locate the two retaining screws.2
Remove the two tail light retaining screws with the Phillips screwdriver.3
Twist the tail light bulb and socket to the left and remove it from the rear of the tail light assembly. Set the old assembly aside.4
Place the tail light bulb and socket into the rear of the new tail light assembly and turn it to the right to tighten it into place.5
Put the tail light assembly back into place and replace the retaining screws.
