If you're looking to upgrade the lights on your Model 3, then you might find that the cabling is a little tight, particularly in the doors. It doesn't apply to all Model 3's, but it does seem that 20-25% will have at least one cable that's too short. Our LED extension cables provide a 5" extension, and provide more than enough slack to allow for the perfect installation. Our LED extensions are compatible with all the bulbs we sell (and of course, the factory bulbs), and with Model 3, S and X.
Sold as a pair.
