Inquiry (采购产品): 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. **** Hidden Message ***** Jessica Clark 40299 Company: Beams Roofing and Contracting E-mail: jclark@beamscontracting.com **** Hidden Message ***** jclark@beamscontracting.com
