How to Install: 2024+ S650 Mustang LED Reverse Light | Form Lighting

[@SuperRedalert1234]

It seems the connectors for the reverse light that comes with the GT premium with upgraded speaker system don’t match the harnesses that are given with the reverse light

We have tested on the GT and did not find this issue initially. I am not sure why the speaker system would change the tail light connectors but I will have you reach out to our customer service team and they will gladly help resolve this issue for you. I have also mentioned the fitment issue to our engineering team so we can look into this further.

I have the same issue. My approach lighting doesn’t work.one tail light doesn’t work but if i unplug the harness and plug it back in as factory it works. The wiring seems to be faulty plus the 4th brake light doesn’t strobe as advertised. Disappointed

This is not something we have seen before. I will recommend that you reach out to customer service and they will be able to help you work through all of this or potentially send out a new set. This is not something I am familiar with so I have passed your name along so they know to lookout for your message.
