I want to replace my dome lights with blue lights. I pulled them off and noticed that they are not bulbs, but a small flat led diode panel with 4 little diodes. Dose anyone know of a supplier of aftermarket replacements? Or if they can even be replaced?

 

Suggest a search on replacing the LED dash console lights with another color. This is a more common change for owners and about the same job as what you want to do.

Might try Toyotanation.com in the appropriate Camry year section for better input from those who have actually done the change..
