How do I replace my tail light bulb in my 2003 LS430

 

If you pop the trunk, you should see a cover over each tail light. you can just snap those open and should see the bulb attached to an adapter, pretty self explanatory. Remove old bulb, in with the new one.

 

Make sure you get the RIGHT bulb....By getting the wrong bulb, it will fit and work but, your dash light (taillight out) will still show up....Read my tread on this, every light was working but, the dash light was coming on...

If it's something like a plate light, there are plenty of threads around here on how to do it, do a search, you should be able to find what you need.
