First, this is not going to be the most useful light you can buy. The main light works good. The LEDs are for show or giving to kids as a toy. They run randomly in various sequences like some light show with a rock band. The grandkids love them, and maybe your kids or grands will also. But this is not a serious work or hunting light. I would not buy them again knowing how they actually work. Might be good for Halloween or a party gag, but you won't get any work done with the leds.
