well you seriously did an amazing job for your first retrofit. Let's just make sure you soldered everything well- vibrations can be problematic.Well, I did a little and stopped and came back to it, all in all, with the dual headlight mod and everything it was about a month and a half I think. As I said, that was with like weeks going by without doing anything though. A very committed person could probably get it done over a weekend if they know what they're doing. A noob would probably be best to go about it bit by bit and not rush.
