cam on a tripod. focus on infinity. have lockable shutter remote, and a black card. experiment...medium ISO (high iso not needed), and about F8. use bulb and not a predetermined second setting as its more customizable...esp with a black card.
play with bulb times. you can time the shutter just when the burst is about to go, then once its gone or to the point when you want to stop the light trail...place black card close, in front of lens. remove black card when the next burst is about to go. release shutter lock. next frame. this is a simple way to do multiple exposure and to capture multiple bursts. it also allows you to expose bg light without blowing it out waiting for the bursts.
have fun and experiment lots! remember, the light is very bright, so you dont need high iso or a wide aperture. depending on the frequency of bursts...you can go anywhere from 5-30 seconds...
