This is an inquiry message about Exit signs in the 108th China Canton Fair. (这是一条买家关于"Exit signs"的询盘信息，来自第108届中国广交会。)Inquiry Message (询盘信息) Exit signs I have changed out the light bulbs in out exit signs and they still dont seem to work when the power is out I have tried the test button and it does not work either. I saw another set of lights at the bottom and was wondering how those can be changed out or if you have to change them yourself.
