None of us wants to miss that important phone call. However, as busy as life is now-a-days, this tends to happens, when we are in crowded places or places where there is a lot of surrounding noise.  One gadget that was especially devised to deal with this sort of problem is Light Charms.

These charms come in two types – one with a lava lamp and the other with a mini bulb. They are designed to go off, when your cell phone is about to ring. This alerts you on incoming calls and you will take them quickly.

These devices weight just 15 g. The lights used in them are LED’s and they are powered by 3 x SR60 batteries. However, it is to be noted that they can be used only with 1800/1900 MHZ GSM mobile phones.
