OK, I've been looking everywhere for how to change the parking lights for the 2007 Jazz and couldn't find anything specifically for them, so I had a go at it today and decided to write one (I don't know that much about cars but if this can help anyone then I'm happy

).
The first few steps are the same for changing the headlights. I found the easiest way was to steer all the way to the left (or right) for full lock, then remove the 2 front clips from the fender lining to allow it to be pulled back and "bent" to create the most space for my arm to fit through.
The part we are looking for is the cable/plug near the top of the image. To remove the cable, it needs to be squeezed on both sized to release the clip and then pulled away from the plug.
Once the cable has been disconnected, remove the plug by twisting slightly clockwise and then pulling away. This is what it looks like without the cable attached:
And here is the cable that was disconnected:
It looks as though there is only one way to reconnect it to the plug, so I wasn't worried about putting it back the wrong way

.
Below is the stock parking light with the plug that was pulled out:
I bought a pair of xenon blue kinda coloured parking lights from the local market here in Thailand (they're from Japan).
And here is the plug with the new parking light attached:
Then all there is to do is reinstall everything the way it came out (insert the plug and light back into the headlight compartment, twist anti-clockwise to lock into place, plug the cable back into the plug, "bend" fender lining back into place, insert the plastic clips back into place and you're done!!)
