With a 10cm stem this light is ideal for inspecting and working inside Violins and Violas.
After a year or so of use, due to a build up of corrsion on the switch contacts the light may start to flicker lightly.
To eliminate this, remove the batteries and spray the switch from the outside with Servisol Super 10 Switch cleaning lubricant and work the switch back and forth for a minute.
Due to international shipping regulations I am UNABLE to send lights with batteries included.
They will require two AA batteries. Do not use Lithium batteries as they produce too much voltage.
