Lighting the Lighthouse

Lighting the Lighthouse is an unmarked quest in the Fallout 3 add-on Point Lookout.

The Note
A note may be found by the light mentioning a truck whose load consisted of Lighthouse Bulbs. The truck may be found northwest of the Ark & Dove Cathedral, or SE of Turtledove Detention Camp (not recommended to fast travel to Camp) at a location called Truck Wreckage.

Fixing the Light
Inside the truck is a large collection of Lighthouse Bulbs. The majority of them are damaged with the exception of one. Acquire it, then head back to the Lighthouse. Atop the Lighthouse, walk up to the mechanism and Activate to place the working bulb. Hit the electrical switch on the wall, and the lighthouse is lit... a beautiful sight.

Glitches
When approaching the truck wreckage, there is/maybe an explosion that takes place hinting at the truck wrecking at that point off in the distance. This explosion could cause the lighthouse bulb and other truck contents to go flying off in the air and being stuck in the sky. It is then impossible to complete the quest. (PS3 version)
