Why do street lights twinkle at night when you see them from a distance?

For pretty much the same reason that stars do. It's an optical illusion caused by the bending of light through a turbulent and hazy atmosphere.
If the unevenly-heated air between you and the streetlights happens to contain a mix of smoke, dust and water vapor, then the churning particles and droplets will act like tiny mirrors, shadows and lenses. This chaotic mix will distort the light rays passing through it, causing faraway light sources to appear to flicker or twinkle.
As you move closer to the light, the number of photons reaching your eyes rapidly increases. This tends to average out the apparent intensity of the light, making the twinkling effect 'magically' disappear. (This is also the same way ancient astronomers were able to tell planets from stars, by the way: the planets are close enough to Earth that it took a very turbulent sky indeed to make them appear to twinkle at all.)

When lighting appears in the remote distance and appears to produce no thunder sound it is called?
When lightning appears in the remote distance and appears to produce no thunder sound, it is popularly known as "heat lightning." Meteorologists will tell you that there really is no such thing as a distinct type of lightning that is not followed by thunder. All lightning produces thunder, but it is only audible for a distance of some 15-20 miles from the storm. At night, lightning can be seen for distances of up to 125 miles if the conditions are right. So when lightning is seen but no thunder is heard, you are simply too far away from the storm.
