You can take photos with light trails if you follow these instructions.
1) You'll need a tripod.
2) Your camera has to be in Manual Mode since you'll be setting everything.
3) If your shutter has a "minimum shutter speed" of 15 seconds you can use the self-timer to release the shutter. If it doesn't have such a long shutter speed it must accept a cable release and have a "T" or "B" setting on the shutter speed. (Either of these settings allows you to keep the shutter open as long as you wish.)
Suppose you want to take photos of a city skyline in the distance after dark. Find a good vantage point away from any light sources. Mount your camera on your tripod and compose your photo.
ISO 100
f4 @ 8 sec.
f5.6 @ 15 sec.
f8 @ 30 sec.
f11 @ 60 sec.
ISO 200
f4 @ 4 sec.
f5.6 @ 8 sec.
f8 @ 15 sec.
f11 @ 30 sec.
If you can find a vantage point overlooking a busy highway you can use these same settings to produce "light trails" - headlights will be long white streaks, taillights will be long red streaks. If you have the city skyline as a background your photo should be very impressive.
The settings are from my FotoSharp (fotosharp.com) Day & Night Exposure Guide. They use the traditional (35mm film camera lens) f-stops so you may have to experiment with the times to "fine tune" the results to your lens' f-stops and your own preferences. Change only the time. Its always best to change only one variable at a time - changing more than one leads to confusion. (Get as close as you can to the f-stops shown in the example. If your lens has an f-stop of, say, f7 you might try an exposure 2 to 4 seconds less than shown for the ISO you're using).
Note to "Leftie 19" Read my answer. It requires a slow SHUTTER SPEED, not a "... slow lens ...".

Photos taken at night of moving cars, etc., with the shutter open a relatively long time, will show streaks of light and little else. If you search, for example, Google images for the words open shutter photos, you should see more examples.
It makes no sense to refer to an aperture being open a long time- apertures are lens openings and can be smaller or larger, but time doesn't enter the equation.

These are called 'light trails', or 'painting with light'. Like stated above, use a long shutter speed to have the light source 'paint' a trail across the frame. Of course you'll need a sturdy tripod and reomote so the image will not be blurry.

Those are long exposure shots, where the shutter is kept open for much longer than normal. Unlit areas dont show, but anything that is lit is highlighted to a point.
There is also "light painting", where the shutter is left open in a dark room, and flashlights are used to create effects on walls, or subjects.

Well here they are:

If you want to take them yourself, just make sure you have a longer shutter speed. It records the movement of the cars on the highway, which explains why the lights are from one side of the road to the other.

It can be done with manual camera and keep the aperture for a long time. You just keep you camera still and adjust the shutter speed for a long time. Try that.
