In that case, I don't see that there is a problem here.

That rubber tube is always broken anyway, so I started sealing where it 
enters the boot with silicone sealant. If your boot is torn or missing, I might 
have a replacement, or you might be able to fabricate something or just use 
the sealant to seal up the backside of each socket.

Also, make sure the lens gasket is good and that the drain hole on the 
bottom is clear. (Isn't there a drain hole somewhere?) I have good 
replacement white foam rubber gasket material available by the foot.

I find a dental tool useful to clean off the socket contacts. Then add a bit of 
grease to prevent future corrosion. Add this to both the center contacts AND 
the grounds. Clean any grease off the glass before you run the bulbs and 
get them hot.
