Installed after some work on my 2016 mx-5. The LED reversing lights (Osram/Sylvania) I installed a few years ago were not as bright as the stock bulbs. On the first try I didn't realize how weak the Sirius LED was and it fell into the case. So I pulled the whole case out and rotated it so the LED would fall out. It turned out that the shank (the flat part where the contacts are located) is a few millimeters longer, which does not allow for correct installation. So I folded the contacts back, carefully cut them off with a heavy duty knife, and bent the contacts back into place. They are put in the nest, beautiful and convenient. As such, they're noticeably brighter than previous LEDs, but may not be suitable for some vehicles. I would definitely not recommend for Mazdas.
