According to one configuration, an electrocautery electrode for use in electrocautery or electrosurgery is provided which has a light-emitting component disposed thereon. The electrode is configured to be inserted into or positioned between components of standard electrocautery pencils, making wide distribution easier. According to another configuration, a sleeve is provided with a light-emitting component disposed thereon, the sleeve being sized to fit on any standard electrocautery pencil. The light-emitting component on the electrode or sleeve reduces shadows and allows improved illumination of the treatment sight without necessitating purchase of a new electrocautery device.
