Lucky shades (Fallout 3)

Lucky Shades are a pair of sunglasses with +1 luck bonus. They can be found on a mannequin doll in a scavenger's shop in a red brick building southwest of Tenpenny Tower near the southern edge of the game area. The building is easily visible from the entrance to Warrington Station. The shop is adjacent to a bombed-out building and a parking lot. The mannequin is in the back of the shop looking straight from the entrance. The shop also has every ingredient needed to make one of each custom schematic weapon. However, the shopkeeper doesn't sell everything he has in the store, theft may be necessary. Lucky Shades can be repaired using any eyewear (eyeglasses, etc.).

It seems the shades can fall off the mannequin. They land on the mannequin stand, and the player character cannot choose to pick them up with the cursor. It seems to happen before the PC enters Lucky's store. So far at least two people have noticed this.

Alternatively, in the PC versions they can be added to the player's inventory with the console. Open the console with the ` or ~ key and enter the following;

player.additem 000CB54B 001

This adds one pair of Luck Shades to your inventory. The "000CB54B" defines the item while the "001" defines the quantity.
