With a #5 Torx screwdriver, unscrew the 4 first Torx screws retaining the wheel inside liner than you will get access to the lamp. Just pop up outside the lamp assembly from the upper part of it, Turn the bulb assembly to disengage it, then take out the incandescent lamp. You are now ready to install the new LED assembly. Just insert the wire in place of the incandescent lamp, engage and turn the bulb assembly, insert the new LED assembly in place and install the 4 Torx screws. Do a test before reinstalling the new LED assembly. It took me 30 minutes for the first side to figure how and install the new LED lamp and less than 10 minutes for the second one.
