Repeater glare and how to fix it (if you dare!)

** Update - We wrongly assumed that the redesigned PCB without holes had eliminated the glare, but it doesn't. Only the 149586x-20-D revision parts have eliminated the glare properly. The -C repeaters still have glare which comes from the glue holding the camera onto the PCB transmitting the LED light into the sensor. We'll post a follow up video soon with more details.**

A recent Tesla software update brought us the blind spot camera function, but this has highlighted an issue with early Model 3/Ys where the camera becomes blinded at night by the repeater LED.

This glare is very distracting for the driver and makes the blind spot camera function less useful, so we decided to investigate the problem, find the cause and maybe a fix.

If you have a repeater affected in this way and are thinking of getting it replaced, please comment below with the part numbers of the old and new units as this will help us track which parts could be used in the future to fix the problem without applying the fix we show in the video.
