The bulbs have aground and a 12V right ?
The ground is the body of the bulb holder , the 12V is a brass spring finger 
inside .
The brass finger is internally pressed against the galvanised steel trace 
wich goes to
the connector , and it's secured only by piece of molten plasstic . Much 
like a a rivet .

That junction causes problems .The brass / steel junction corrodes , becomes 
hot , corrodes a
 little more , becomes a little hotter etc and finally doesn't make no or 
very poor contact  .
To solve this , the easiest way is to drill a small hole in the plastic
between two traces , put an insulated wire trough it , and solder it to both 
the trace on
 the outside and the copper finger on the inside .
You'll need some flux to solder to the galvanised steel , otherwise it won't 
stick .
I have some  pictures of repaired bulb holders if it's not clear .

A more elegant way is to drill out the bulb plate and make it accept a 
separate bulb holder , fi hella has them .
That hoilder has to be soldered to the plate and internally connected to the 
right  traces .
This technique is also a good way to upgrade a normal holder plate to the 
later style dual filament lamps .
Disadvantage is that you need a mill or at least a decent drill press .
Drilling has to be done with a boring head or a hole saw , a normal twist 
drill will most likely destroy the bulb holder .
A round file or a dremel tool will also do the job .
Got pictures of those to should anyone like to see what they look like .
