The light is very bright. You should have no problem tracking your arrow flight to where you hit the animal. The on off switch is easy. It just fits a bit loose on the string. All around great product and aids in tracking the animal and finding the arrow. Arrows and Broadheads are expensive. Just don’t use a Broadhead twice without sharpening. You should definitely find your arrow if it doesn’t go into the soil or way under the grass. Good luck.
