Hi.
A lot of lights nowadays are usually rechargeable via a usb lead. Some nights I often get home quite late after a bike ride and as soon as I get in ,I tend to put my lights on charge. By bedtime there often still in the process of recharging. If your lights were from a reputable shop and well known make would you leave them on overnight to recharge. You often hear of horror stories about cheap Chinese lights catching fire and I'm a little dubious about leaving mine on over night .( even though there of a good make )
Edit:: I incidentally I stop recharging mine before bedtime
