How do you change a tail light bulb on a Peugeot 206 on a W reg?

In your boot there should get access to your lights via a plastic panel. When you remove the panel the lights should be easily accessed, carefully take the defected light out and changed with a new one. Check your vechiles manual or go to the Hayes online site and just type in your make and model and the problem and it should come on screen how to do it.
