Modern Headlights

slantsixdan, I was looking on e-bay at headlights and found these; http://www.ebay.com/itm/331756604500 They look very similar to the ones you posted earlier in the thread but significantly cheaper. I'm assuming that's because they are cheap knock offs and not of the same quality and light output, etc?

Exactly right. They are cheap and nasty—and unsafe, and illegal—Chinese knockoff garbage. Headlite-shaped trinkets. Not worth buying at any price; you don't have to spend a big pile of money to get good headlamps, but you (don't) get what you (don't) pay for. Real/legitimate LED headlamps cost money; if you can't or won't spend the dough on them, then cost-reduce the project by buying good halogens instead, not by buying bad LEDs.
