Tesla

Tesla is an achievement/trophy in Metro Last Light.

Overview
This achievement is awarded to the player for breaking 50 lights by shooting or stabbing them. If the player is attempting a stealth approach through the game, this achievement can be easily earned. Any light that breaks when shot will count, but be careful as nearby enemies may hear the breaking glass, even when you shoot the light bulb with suppressed weapon.

Another way of getting rid of the light sources is by switching them off, doing so 40 times will grant the player a different achievement, Edison, instead.
