how to change neon glass tubes?
We’ve been asked to change a neon tube for an existing interior shop sign, and our customer is providing the replacement tube for the sign (which they probably had made at there head office in Europe and shipped to the UK for fitting)
As I’ve only worked with LED and fluorescent tubes before, so I’m not sure what’s involved in changing neon tubes, and as the shop is over 150 miles away from us, it’s not practical to look at the job in advance.
Any tips from someone that’s done this before would be appreciated 🙄

Hi Neil
1st thing is the high voltages involved. Switch everything off and remove the transformer cover. Properly test the low voltage side to make sure it is off. If you are not sure do not mess about with this get an expert to do it for you!!.
Hopefully the broken neon section has a silicon cover at each end. Remove these and you will see 2 strands of nickle wire coming out of each end of the electrodes at each end and there will be a cable linked at each end Untwist the cable and seperate from the nickle unclip the broken section and replace the new section following previous steps in reverse.
Kind regards

Hi Neil
Should be a lot easier than my explaination….lol. Just make sure its switched off while you work and that the silicon covers are replaced on the electrodes when you put in the new section so no bare wire is showing.
Good Luck
