Frankly, these lasers...

These are not what you see in real life. You dont see a bar - you see a streak, its very bright but it doesnt look like what is in the picture. Yes it does have a laser like quality, but so does a sprinkler if you swish it fast enough, which is closer to what a tracer looks like. The problem for me with the picture itself is that the light/bar is even in its intensity which it shouldnt be. Front end should be alot brighter then the back. Its a residual image, not a bar.
