Can you post their datasheet or a link to it?
Im not sure if i can post a link here, but if you were to search ebay for" RGB 5050 Waterproof leds" im sure youll get the exact same led strip.
Are you sure about the current?
That i am not. As i haven't put an ammeter in series to verify current.. The specs on ebay says .2A per led, 300 led per strand though.
As for law, im not to concerned about that portion as i wont drive with them on. I just dont want to make the mistake and remote start the vehicle with lights on. also im pretty sure cars are not allowed, BUT motorcycles are! i do have rgb on my bike, but controlled from an atmega328, and transistors..
