Ok well, like I said, just trying to share ideas. I usually only think building from scratch is a good idea if it's cheaper than buying pre-made, or if you can get individual components of better quality than pre-made. You said you were worried about some of the components handling a beating, just saying, my system has been put together since last summer, and I only had trouble with two components. One was the first toggle switch I was using, couldn't keep a good connection due to vibrations. Replaced it with an automotive quality switch, no problems since. The other was the first bottle genny, that's another story but suffice to say it's replacement is holding up just fine. It looks like you've done a good job, but unless you're planning to market this setup and the prototype is a test bed, you've gone to some unnecessary trouble and spent a good deal more than you needed to. If you are planning to market that setup, good luck. Very few people here are going to buy a $400 lighting system for a $250 homemade moped. You're better off marketing to hipsters. Not trying to be rude, just telling you the truth. If you can cut the price in half, you might get a few more customers. But considering the fact that a guy like me can build a lighting system without much prior knowledge of circuitry, I'd say the chances are slim. It took me some time to figure everything out, but I did it. I started with two r/c car batteries wired in series and an incandescent bulb for the brake light. Switched those out for an led and an sla battery. It worked better, but I got tired of wall-charging every so many days and decided to build the charging system. My point is, imho, most mab enthusiast will probably buy pre-made lights that run on batteries, such as the cree brand that's becoming ever more popular, or if they want to go all out like I did, they'll do their research, scrounge whatever parts they can, and buy the rest pre-made. There is a certain percentage of people in this market who will buy expensive items, collectors, show-piece quality builders and those who use their money to build fleets of fancy toys. But that's not the majority here. Of course, if you're building it for yourself, then I'm sure you've got your reasons for wanting to do it this way. Either way, I don't mean to offend. Just trying to share ideas and insight.
