Custom lights

[DBR_ONIX]

Hello...
Have a look at This page of the forum..
I though maybe someone here could help out..
Bascily what I'm wanting to do is make a laser beam from the car head lights... (Yea, this sounds weird, but read the other thread, and it'll make sense)

Is it possible to make custom lights (Change colour, shape ect)?

Thanks so much!
