Leak lights help repair technicians inspect how well woodwind pads seal against their tone holes. Placing an appropriately sized light inside the instrument can reveal illuminated gaps beneath a closed pad, helping identify areas that require adjustment. Leak lights are useful during repadding, routine maintenance and troubleshooting on saxophones, flutes, clarinets and other compatible woodwinds. Choose a light that fits the instrument body without creating pressure or damage. For best visibility, inspect the instrument in a dim workspace and check each pad from multiple angles before making adjustments.
