where can you get them? I have found one site that has an upgrade kit from 1.2v to 2.0v
don't know if adaptable? In my sevice manual it says to use bulbs with red caps,can not find these. Are the old caps reusable? please help I can not see my speedo at all!!

 

Not sure exactly what cluster you have but from the sounds of it, its an older one. Sometimes parts like that arent availble thru the after market. Surely a dealer could locae them thou.
