Brighter: You have already done an LED upgrade to the headlights, the fog lights, and the tail lights on your Tesla, so does it make sense to keep the Interior lights stock? No way. Now you can complete the package and make sure everything matches both in terms of output intensity and purity in color with these assemblies. With high-powered Osram LED's behind the optical lens, they will be much more effective both day and night compared to the OEM setup.
