Pokémon HeartGold Version Tips

Ok you know the lights in Ecruteak city? Well a friend of mine told me she was riding her bike and ran into one and mashed the a button. She got an ultra ball out of it. So I tried it out myself and I found a great ball, so next time you see one of the lamps check it you never know what you can find. But you will have to be patient, it's just like looking in the trash cans you might not find anything but then again you just might find something rare.So yeah thats all.
