I gave up on them yesterday. After cutting into the windshield cowling, chipping the edge of the hood, and then stripping out the bolt hole I just quit while I was ahead...well not really ahead but you know what I mean. I am going to try and find longer bolts before I try again. I think they are a little bit too short and didnt have enough to grab onto when It was just about tight enough. I also need to find a better tool to work those back bolts, maybe an angled wrench or something? And I really thought the electrical aspect of this project was going to be the hard part! Next weekend...2nd attempt. On a positive note: the lights are great, really solid and the quality is definetly there. I was very impressed with the packaging too.
