Animal Crossing
In and, the lighthouse is found near the ocean and turns on when it starts to become dark. Once a year, in an event known as Tortimer's Vacation, the mayor will ask the player to turn on the lighthouse every night for seven nights. This is the only time the inside of the lighthouse can be seen. If the player turns the light on each day, Tortimer will reward the player.

Animal Crossing: City Folk
In, the lighthouse is obtained through donations to the town fund. Once the fountain is obtained the player must donate 1,000,000 Bells, at which point either a lighthouse or windmill will be built. All of the players in the town can vote, and if the majority votes on a lighthouse, one will be built.

Trivia

 * It is rumored that if you have the lighthouse, it will increase the chance of rare fish appearing. However, evidence has been inconclusive on this claim.
 * There is a way to glitch the game so that you can walk on the lighthouse. The way to do it is having one player run up and down on the right side of the light house, and another player stand behind the light house and dig at the very end. When the player running up and down gets stuck behind the hole (that shouldn't happen, it's not a normal hole) the player should spin around until they get on top. To get the other player up, the player that is on top must stand in a certain position to where they can dig down as the player that dug last time runs up and down until that player is up. If you save the game during this the players will faint as if they were bitten by a tarantula/scorpion and visiting ones will appear at the gate and the owner will appear at their home.
