We have a bulb gone indication light come on on the dash of our 2009 Swift Bolero. All lights ok but cannot see a fog light coming on, so assume it’s the F/light bulb blown. How do you get the lens cover off to change the bulb? The whole cluster turns round but the lens cover will not come off. I guess it must unclip somehow but I don’t want to break the lens as we are off on a trip in a couple of days. Any body changed a bulb lately?
