[tucka_5]

Recently one of my brake lights wasnt working so i changed the bulb. In the day when my lights arent on it works fine but at night when i switch on my lights the bulb i changed in constantly on. Anyone know how i can fix it?

I don't know if that's a dual filament bulb or not, but it's either the bulb is in wrong or you have a dodgy earth and the sidelights are earthing through the brake light circuit.
