ABSTRACT:
A flashlight which includes a telescopic assembly for shade and a positioning assembling for a switch socket is provided. The telescopic assembly is facilitated by the slidable engagement between spiral grooves disposed at an outer wall of the headlight housing and projected bosses of the shade. When the shade is rotated, the shade is moved along the spiral grooves to extend or retract. The positioning assembly of the switch socket comprises a switch socket, a biasing plate and a water proof push button. The switch socket assembly is positioned by application of biasing plate. Consequently, excellent positioning and water proof effect are attained. The shade of the flashlight can be readily adjusted to move in for application of spotting an object or move out for application of a traffic signal baton.
