Hi there... I had the same problem you do with my CF lights. Since you mentioned that you've already opened the module up and cut one of the pins on the IC I assume you don't mind making modifications;) In that case, all you need to do is open the module back up and cut the lead on the diode in the picture here: (I have no idea if that's gonna be an active link... hopefully it is. If not... well... copy and paste, I guess;)

HTH,
Brett
