help please

hi all,just wondering if anyone could help me,i use a program called proteus to build and simulate circuits and only being a hobbyist i only know the basics of the program and build simple circuits,now what i need is a neon lamp that conducts at 200v but there is only one neon lamp in the program i have and it doesnt seem to work when i put it in a circuit and simulate,does anyone use this program that would be able to tell me how to change the values to 200v or even better so the value could be changed to any thing i wanted,like you can with for example the resistors,thanks for any help.

you can consider using other simulators lilke MultiSim or Circuit Maker. MultiSim (EWB) has the option of changing the ratings of almost every component.
