1. A surgical instrument comprising:
a handpiece comprising a body portion;
an electrosurgical end;
a light source coupled to an external surface of the body portion;
a light pipe extending from a proximal end adjacent to the handpiece to a distal end adjacent to the electrosurgical end, the light pipe configured to receive light from the light source through the proximal end and to transmit light from the light source to the distal end;
wherein the light source is configured to move between:
a first position, wherein the light source is configured to emit light from the light source at a first, wide illumination angle; and
a second position, wherein the light source is located relative to a light cover such that light is emitted from the distal end at a second illumination angle narrower than the wide illumination angle.
