Clicked on the links but came up no product available. Could you please give me more details so that I can search for it myself?

Thanks

I have the macro drive front light. It flashes green when charging but before long goes constant green. when I switch it on it lasts about 30 seconds before turning off. There is no red low battery warning. I can turn it straight back on and again it lasts for 30 seconds only. has anyone got any ideas please?
