these are the same great lights used for our top-rated Ultra Bright LED lights, but with a blue lens. Recommended for use in the in-direct lighting locations, i.e. foot wells, they add a subtle touch of color and ambiance to the interior of your S, X or 3. They are a plug 'n' play replacement for the OEM bulbs that came standard in your Tesla, the same in every regard, except being 16x brighter. And blue :-)
Buy as a single light or 4-pack depending on what you need.
