I am ready to change the the bulbs for my 1950 f1 to 12 volt bulbs. Most replacements are relatively straight forward since I have separate turn signal lamps wired front and back by a previous owner. Thus I don't have to rewire the bases in the parking/tail lights for dual filament bulbs. My questions are about the instrument cluster lights and the hi-beam bulb in the instrument cluster. My shop manual doesn't show how to access these bulbs. I assumed that the bulb holder bases could be pulled out from the back of the cluster to expose the bulb for replacement and then pushed back in for a friction fit. However, it appears to me that the entire cluster has to be removed to get to the bulbs. Can anyone clarify the procedure for me ?

The second question that I have is if anyone can tell me how much current the three gauges (fuel, oil, and temp) draw? I've had people tell me that they only draw approximately 1/4 amp each, but surely that must vary depending on what the gauge is reading. Can anyone clarify what the max current these gauges could draw? Thanks.
