I have had a few light kits in games for testing for a couple of months now. All has gone well.
This past week I sent out a couple of more sets to a customer with a link to my install instructions (that are still being compiled). I should be getting feedback soon from them on the install, the install instructions and the actual light kits.
I have designs for Batman 66 and Aerosmith ready, but have hit a small delay concerning some other designs moving forward. This is something that may take a bit more time to get resolved, but when it is, it shouldn't be an issue moving forward.
