Open Dromed. Go into the object hiearchy and find an existing object that resembles the item you want to use, crerte the objcet then Edit->Add->shape;type in "stgaslamp74" (without the "")(Do not add the gaslight to the existing gaslight hierarchy. If you do it will inherit gaslight's particleattachment link. It'd save a bit of work if it was possible to extend gaslight, but I'm not sure if it'l work properly.)

Or create a new item under Physical, this way takes more editting but you can get closer to what you want.
First go to Editors->SFX -> FireFX -> FireParticleFX -> TorchFX
Highlight the TorchFlameYellow (do not open!)
Click Add, a new window will pop up, type in: StreetGasFlame, Click OK
