You did the right thing that asked this question! There are no "not important" questions when you select your future jammer that you would purchase and use to deal with your problems. As for the indicators, most jammers have them, at least one indicator showing that the power of this signal jammer is on and its working now. But there are even more.
Signal jammers like this one have two LED indicators to show working and recharging operations separately. There are also other types of indicators like this signal jammer has. Those LED lights are located at the top side of the jammer and separated according to the jammed bands that are working now and thus their LED indicator is lighten up too.
Thus when selecting your signal jammer look carefully and think about what indicators you need them to have.
