If you mean the little bulb some call it a side light, others call it a position lamp.
This video shows how to change a sidelight/position bulb .You can find similar videos on you tube for changing a headlight bulb. Unfortunately it does involve accessing via the wheel arch liner. And thats the 'easy' method. I think the 'official' way is to remove the entire front bumper.
The Jazz is not alone these days in front bulb replacement being a bit of a palaver.In these cases the drivers handbook may not show how to change the bulb but just recommend having it done by a dealership.
Places like Halfords that may offer a bulb fitting service at low cost may charge extra for more complex cases.. But as the video shows it can be done as a DIY job. .
If possible have some replacment 'plugs' available before starting the job as they sometimes break.And the correct bulb
If the car in the video appears to differ from yours maybe do some more research before starting as access may be completely different .(and easier)
