I have a quick question. My car was an A4 but the previous owner did the A4 to M6 swap. Now the reverse lights aren't working and I was wondering if there was any way I can get them back to working. I know you really don't need them, but I'm thinking about putting 5% tint on my hatch glass and it would be really hard to reverse at night and have to look through 5% tint without reverse lights. Thanks for the help, Ryan.
