The Lexus LS430 is a full-size luxury sedan that was produced by the Japanese automaker Lexus from 2001 to 2006. The LS430 was the first model in the LS line to be equipped with an all-aluminum alloy 4.3 L V8 engine and featured a six-speed automatic transmission. It had a 0–60 mph time of 6.3 seconds and a top speed of 155 mph.
In 2003, the LS430 received a minor facelift which included new tail lights with LED bulbs.
If your Lexus LS430 is equipped with the optional LED tail lights, you’ll need to replace the bulbs differently than on other vehicles. The entire assembly must be removed and taken apart to access the bulbs. It’s a bit of a process, but not too difficult if you’re comfortable with taking things apart.
Here’s a quick guide on how to replace the 2003 Lexus LS430 tail light bulb.
First, open the trunk and locate the two screws that hold the tail light assembly in place. Remove these screws and carefully pull out the assembly.
There are three wires connected to it, so be careful not to yank them out.
Once the assembly is free, take it over to a workbench or counter where you can disassemble it. There are four screws holding everything together – two at the top and two at the bottom.
Unscrew these and carefully pull apart the housing.
Inside, you’ll see three LED bulbs – one for each taillight ( brake light, turn signal, and reverse ). These are all held in place by small metal clips.
Gently press down on these clips and remove each bulb from its socket . Be careful not to touch any of the glass surfaces on the bulbs as this could cause them to fail prematurely .
Now that all of the bulbs are out , you can start replacing them one at a time .
Match up each bulb with its corresponding socket , making sure that they’re facing in the correct direction . Once all three bulbs are installed , screw everything back together , reattach wires , and reinstall into vehicle . Test your new bulbs by turning on your Tail Lights/Headlights switch .

-How Do I Replace a Tail Light Bulb on a 2003 Lexus Ls430
Assuming you are talking about the brake/tail light:
You will need a 10mm socket and ratchet to remove the two bolts holding the light in. Once those are out, there are three clips that hold the wiring harness in place.
One is at the top near where the bolts were, and the other two are on either side of the bottom of the light. Pry these up with a small flathead screwdriver and wiggle the light out.
The bulb itself is held in by a metal clip.
Push down on one side of this clip and pull the bulb out. Put your new one in (it only goes in one way) and put everything back together in reverse order!
