Silverlight Dagger 

Weapon (dagger), common 

This weapon is considered to have the silvered property. 

As a bonus action, you can command the blade of this dagger to shed silvery light, creating bright light in a 20-foot radius and dim light for an additional 20 feet. Also, as a bonus action you can extinguish this light. 

Even without the light effect active, the blade of the dagger always seems to glint in in whatever light is present.
