This time in Fireworks tutorial, I will teach you how to create a colourful glowing light trail. This is rather a simple tutorial that can be performed in only 6 basic steps. So get ready to create something like this:
First, create a dark blank canvas in any size of your choice. It is not necessarily black. For a better result, you can use a dark background image as well. But in this tutorial, I will use a blank black canvas.
Second, draw above shape using the Pen Tool and play around with the points using Subselection Tool(A) to get a smooth curve on the outline.
Draw a few of them with various orientation and curves. While in this process, you may want to put a bright color for the outline and transparent [#FFFFFF] for the fill color to make easier for you to work on a dark background.
When you are done with your shape, remove the outline color and fill the shape with any bright color. I am using #FFFF00 for this first shape of mine.
Now, we want to work with the glow. From the Properties pane at the bottom, click the + button next to Filters > choose Shadow and Glow > choose Glow. From the Glow setting, set the value as shown in the following screenshot.
The values are not fixed - you can play around with it until you like what you see 
And yeah, it is better to choose the same color of the glow with the color of the shape itself.
Optionally, you can alter the coordination of the shape using the Distort tool. This will make your shape are coming from the very back towards the screen - yeah right . But hey, you can try out.
As you create more and more shapes, combine them all - play around with the layers position. If you look at the green shape, I used the distortion method - making it thicker at one end and thinner on the other. Yes, you can manually do that, but thats another alternative.
Finally as you can see in the final outcome, I added few small circles around the shapes to enhanced the area.
Good luck!
Update: Here is the source file of the final result.

11 Dec 07 | 1:50 amnice tutorial… tapi kalo ditambah lagi glow kat keliling tu aku rase lagi bertambah menarik n tambahkan sedikit blur effect. blur effect tu maskingkan dalam layer tail tu. dalam fireworks leh wat camtu ke.? raseye dlm photoshop jekan..? tu pendapat aku je…
