Default 2002 SC430 Third brake Light failure

This assembly appears DOA and I understand that it cannot be serviced...does anyone have any other understanding or relevant experience?
There are several companies offering replacements but I cannot determine if these would cover the existing profile, which I need to know before I heat/pressure/remove the existing assembly from the trunk.

Default Third Brake Light Problems

So I went ahead and removed the assembly from the trunk and opened it to find a 10" PCB with LED's solder-attached and no evidence of deterioration.
I tested the board/lights and they came on momentarily each time I turned-on the ignition and pressed the brake pedal. But with the pedal pressed I could never get the lights to light again until I turned off and on the ignition.
Does anyone have any experience or guidance for me.
Thanks

Did you measure voltage going to the light assembly when it works and when it doesn't? Perhaps the problem is not with the light itself..

Not an answer to your question, but if you decide not to fix it, I don't think you have to have it working to pass inspection. I believe in most (all?) states, the center brake light is a federally mandated manufacturing requirement, same as bumpers that can withstand a 5MPH impact, but not an operating requirement.

Default Third Brake Light Fixed

Thanks for your inputs....but as I cannot work on my car in our condo garage, I decided to appeal directly to the Lexus dealership GM, who was very responsive, and the problem was resolved by them installing a new luggage department ECU.

How did you re-attach the brake light to the trunk.
