Ok, so not proficient in changing light bulbs... I have taken out the bulb before and put it back in so I know how to do it. I wanted to put in an adaptor so I could put in a colour changing bulb. I thought the adaptor was the same as the bulb I currently have but it wouldn't push in and then twist ( I have a bayonet lightbulb and fixture). Now I have put the bulb back in but it won't light up. Also I have now flicked the switch so much I don't know if the electricity is on or off. What should I do? I know not to fiddle anymore! Don't want to get electrocuted... do I need an electrician????
