Can i get some help

I just got my beacons and they do not work I downloaded the app but it says it cant find any beacons
Should there be a indicator light to show their on ?

Could you provide some more details? What phone you are using (motel/type)? Android or iOS? What version of operating system?
Have you checked if others apps like nRF Connect are properly scanning beacons?
What version of Estimote app you have downloaded? We recently updated it, but Google Play might need some time to propagate it to all users (incremental rollout)?
Beacons are always on (unless battery is empty). Indicator light would quickly drain battery. Light is only on when connecting or when it is explicitly turned on in SDK.
