After shaping, the hollow tube is evacuated with vacuum pumps and filled with gases to produce the desired color, e.g. neon gas for red lighting. Electrodes are placed at each end of the shaped tubing and the entire tube is sealed to prevent gases from leaking in or out which leads to tube failure.<ref>{{Cite book |last=Miller |first=Samuel C. |url=https://archive.org/details/neonsignsmanufac00millrich/page/n15/mode/2up |title=Neon signs; manufacture--installation--maintenance |last2=Fink |first2=Donald G. |date=1935 |publisher=New York, McGraw-Hill |others=Prelinger Library}}</ref>
