Help!
how do I change High mount stop light for my 2000 RX 300

 

As best I recall, from a year ago, you pull off the inside plastic panel that covers that area and it is plainly exposed. There are plastic snaps that hold it on and can be tough to pull out, but that's how it comes off, as I recall.

Mine failed due to bodyshop work on the rear hatch causing vibration, or so I suspect.
