Pulse jet engines on a 737????

I wish I could have kept this bigger there are rules that we must follow so I'll try to explian it.
The two circles with arrows pointing at them are the default planes and the other circles are the "light exhaust". The little purple "hash" marks look like little rings of light, like a pulse jet engine. This seems to only occur at dusk or dawn and only with the defaul jet aircraft and only at one of the two "Simflyers Scenery" Airports I have . Not complaining just thought it was neat.
