I too have an original Trout Lite. Dealing with Mr Trout has been nothing but a pleasure. Given we've never done more than exchange e-mails, he's a very trusting, top bloke in my book. My TroutLite saw me round my dusk & dawn laps at SITS this year with no problems. In fact, I was little sad not to try it the small-hours but that's the way the times panned out for our team.
One of the guys I ride has a set of lights from one of the German companies – I forget which. He was hacked off with having problems, so found a number for the factory and rang them. The bloke who answered told him that the owner wouldn't give a **** as he was making too much money. Now that is customer service.
I also think it's a plus that Mr Trout is using off-the-shelf components. If he does decide to move to somewhere sunny with the vast proceeds from this project, you can still source spares yourself.
