Remove the light assy and turn the bulbs counterclockwise to remove them.
Open up the hood, and go in behind the fixture where the light is located. Sometimes there is an access panel on top. Open it and reach down inside and grab the bulb's socket. Twist the socket a quarter turn counter clockwise, and pull out the socket. Grab the bulb, and pull it straight out. To replace the new bulb, never touch it with your bare fingers, as this will greatly shorten the bulb's life, if it even work's at all. Use a tissue or something else in that order to handle the new bulb. Push the new bulb into the socket, put the socket back into the housing, and twist a quarter turn clockwise to secure the socket into the fixture.
FOR 99' ES300 MODELS: You do not have to do the things mentioned above. The process is much easier and simpler. No need to even open the hood. All you have to do is pull the whole turn signal assembly forward. NOTE: It is important that you do NOT pull it sideways or even at an angle for it might break the plastic clip. There is only one clip holding the assembly from the frame. To start, use a screw driver or similar and insert it in the farthest part of the signal light assembly from the front. Pry gently to move the assembly forward about an inch or two to completely unlatch the plastic clip that is holding it in place. This clip is located in the middle of the assembly. Then remove the assembly still attached by the wires. Twist the lamp holder out of it's socket to replace the busted light.
