One thing I read somewhere that I will mention just in case: gages in some panels will apparently leak lubricant if tipped. I was cautioned to have a box with a vertical slot or something to old the panel nearly vertical after removal.
Sorry if that's bogus info. Please let us know how it goes - I have a light that is intermittent and should do the same thing some day. For now, the light works more often that not, but that will no doubt change.
