Replace 2003 LS430 tail light Lens Assembly - Lexus Cars & Trucks

SOURCE: replacement of rear outside tail light assembly

If you're asking how do you change a taillight bulb, then follow this procedure:

Open the trunk lid.

Disconnect the connectors from the taillights (taillight bulb connectors are visible by looking inside the trunk at the back of the tail lamps.) There may be an interior trunk trim panel that you have to take off but in most cases its just a series of thumb screws that hold them in.


Brake Lights/Taillights: 21/5 W

Rear Turn Signal Light: 21 W

Back-up Light: 21 W

Rear Side Marker Light: 5 W


Turn the bulb sockets 45 º counterclockwise to remove the bulbs.


If you're removing the taillamps with the bumper off there are 3 nuts and screws that hold the taillight to the rear panel of the car that have to come off from the inside of the trunk.
Remove the nuts and screws, then remove the taillight.

hope that answers your question

SOURCE: How do you replace rear tail light assembly?

Open the trunk and along the bottom of the tail light, there should be a Philips screw securing a cover piece. (your car may or may not have this piece)
With the cover off, there will be another 2 screws securing the bottom of the tail light assembly. Remove the screws and pull the bottom out and the top is held in by two retainers that should just slide right out

You'llhave to raise the rear compartment door fully. Next locat the tailight you wish to replace or same if you are replacing one of the tailigt bulbs. This would include the stop bulb or turn signals etc.
Next there is a black plastice side panel located between the lamp assembly (the entire plastic housing) and the inner portion of the rear compartment door. There you'll see two phillips head screws which you must remove. This releases the entire assembly.
You then next gently give it a small tug toward the left (if a left side assembly) or to the right if other wise. What happens there is that there is a stud that's held pretty snuggly by a modled ring in the body assembly. Don't twist the lamp assembly up or down unless you want to break this off but give it a slight pull outward. Then you're done. The entire assembly will be released and you'll be home free for changing any of the bulbs or even replacing the entire assembly. W/o breaking it of course.
