Night Time send off ideas!

Hello! I’m looking for some creative ideas for night time send offs (that will show up well for pictures). Our reception is in a cave, and the venue will not allow sparklers near the cave entrance because all of the smoke will be sucked into the cave. They will allow us to do sparklers in the parking lot (but this will require golf cart transportation for and a lot of other added hassle) So I am looking into other ideas! (If you happen to have pictures of things you have tried that would be awesome)
