The size is similar to a credit card and there is no wiring needed. Very convenient as it can placed inside a wallet. This product contains a built-in LED light, which is activated when folding the bulb upwards. To deactivate simply fold it down again.
a great night lite - I like and use so regularily I purchased 4 more and placed them in convenient places - BR - Housecoat pocket - office - purse and gave my grandson one to use for night time BR trips. A very good idea and battery change is so easy. Irene
