wondering how to increase trail on missiles

[Drain Pipe]

I'm working on making a lazer missile but for my i simply want a missile that leaves a lot of trail so it looks like a beam when it's fired. I'm pretty sure i can do this with model models that leave a trail, but i'm not 100% sure how in notepad. If someone could tell me what i'd have to modify to attain the desired effect, that would be nice.

Decrese the height, increase the width. Increase the lifespan as well

i don't want it to come out looking long already, i just want to increase trail to make it look like real lazer and not have an odd effect when it is sent out as a missile. I'm thinking that ,making the model longer will make the missile look more lazer like, but less natuiral. But lifespan might work...
