When it comes to smoke alarms most people forget that they even exist. It’s hard in our busy lives to keep any eye on the little things whether it be the smoke alarm, the fuel gauge on our car or our dignity.

These doohickeys screw into ceiling lamps as you see here in between the bulb and lamp itself. It uses the electricity running through to the bulb to recharge the alarm so that you don’t have to replace any batteries. These puppies will set you back $39.99 but can you really put a price on safety? Yes, yes you can and that price is $39.99. Hit the link to see the product page.
