This is a nice compact flashlight that works well in most situations. However if you have multiple lights it will just have an alternating time pattern. If you want all the lights to flash at the same time, then that's fine. If you want them to alternate, you have a pattern.on.off.on.off. I still love the headlights and am returning them for the Z-4 which are two tone and don't have the above issue.
