1 sets of light for mounting on helmet. about 3 years old , Homemade but work well. Lights design to mount on helmet with Velcro (already on lights). Each comes with 12 v charger & 12 volt battery. Lights are approx. 30 w, which is plenty if you are in the middle of a forest.
Each also has a red indicator on back and on/off switch.
They last a bit over 2 hours of continuous use and the battery normally goes in your camelbac or back pack.
Pretty handy for use arround the house as well.
