Hello all. I am new to this foum and very inexperienced with electricity. I would like to make an LED tail light/brake light for my motorcycle. I was looking at a YouTube video that explained how to figure how many LED's to each resistor. But what I am trying to figure out is how do you make the LED's go from dim or medium intensity when it's the tail light to bright intensity for the brake light. Are there special LED's for this or is it just the power settings. Any help or advice would be greatly appreciated. Thank you.
