That's good to hear. I actually ordered a roll of those yesterday. Did they actually get to you in less than a week with the standard shipping? That's good news if that's the case. I have some time to play around while I'm sending my projectors out to be modified. I used my Flexfire ones for something that I ended up not liking. Sounds like they are the same as the Flexfire ones except these are 5mm wide and the FF are 10mm wide. BTW, I think they're 1200-1400 lumen per meter, not per foot.
I don't think they'll be too bright at night, but if they are, the module I'm using for DRL has a wire I can hook up to the low beams which will turn them off when the low beams are on. I think they can be dimmed, but the wiring to make that happen might be more difficult.
