Gas Level Indicator

Have you ever run out of gas in the middle of a BBQ? Use this new indicator and you will never be caught out again. Whether for your barbecue, space heater or kitchen cooker, this useful magnetic gadget keeps an eye on the level in your gas tank all the time it is lit. Just place the indicator near the bottom of your tank and once the level falls to within its range, the bars will gradually change colour to alert you as the gas tank empties.
