I've already replaced the light bulb but it still won't work
The old bulb was shattered to pieces, so could there be a blown fuse or something? I've been driving like this since last May, but never got round to replacing what's broken as the visibility at night is decent and almost identical as before. It's just very annoying to have the fault light on all the time...The little LCD display under the rev counter is leaking crystals or something lol
