Lighthouse bulb

The  is an item which is added to Fallout 3 in the Point Lookout add-on.

Found at the Truck Wreckage, it can be used to fix the signal on top of Point Lookout's Lighthouse.Since there is no reward for fixing the related unmarked quest you may want to use it as a decoration in your house.

Bugs
If unreachable, it can only be obtained by using console commands. (PC only)
 * Sometimes the Lighthouse Bulb will not be in in the truck. Instead of, the Lighthouse Bulb and maybe some other objects normally being in the truck can be found stuck in the air, relatively near the Truck Wreckage.
 * Sometimes, you'll see the floating objects (as mentioned above), but the Lighthouse bulb will appear on the ground on the outside of the truck on the northwestern edge of the trailer (if you are looking from behind the trailer). It's under the trailer, but visible.
