Do I need to change plugs ?

The light is not on but it was flashing on and off

What do I do ?

I can't remember but have you checked the manual for whatever it means?

My brake light bulb was also out

So whent to halfords get new ones

After fitting new bulbs on both sides all gone back to normal

Thank God for that cos I was just about to freak out

The spiral plug light would have be the bulb warning light that comes on when a bulb is out.

Well now I know
