So i've got most of the parts thanks to you awesome guide! However, i can't find the exact same LED where i'm from. i did find a few that i like but they come in different voltages, there's a 3-6v and a 12-24v version. Which one do i choose then and why? Can it be dangerous if i pick the wrong one? And, i often see resistors being put in between the LED and batteries, is this for safety?
