Twinkle little light / Light

Twinkle little light

Twinkle little Light (TLL) could be used in order to making a place light up a moment.
The small LED lightings which are had within can be used by the low voltage of battery charged with solar heat. If users want to light up a moment in dark place, just they would post the ‘TLL’ on the wall when user wants to make the place become bright. If users want not to use, just they would post the ‘TTL’ on the window by using an absorber in TTL.
To put on the window in the daytime helps TTL charge with solar heat naturally.
It could make user conserve electricity resources by using ‘TTL’ instead of turning on the other lighting.
