This is my customers 3rd brake light that is so heavily damaged by corrosion since the Lens has a crack. We restored it! Up for the Challenge :)
What makes it so tiring to Restore is the number of LED's with PCB that is so contaminated ...corroded, that makes it hard to de-solder the old soldering lead. Heat transfer by the soldering iron is poor if the old leads on the board have heavy oxidation.
