More than 3 years ago, a Viessmann 6384 railway lamp was bought. Besides aspects such as painting, positioning and wire placement, one thing of interest was how the light bulb is changed, in case it fails.
Removing the plastic hood is rather quick, although some force needs to be applied. Next came taking the light bulb out. This proved more complicated for me, so with help from Viessmann's support, it turns out the brown wire has to be gently pulled inside the mast. Using some sharp tweezers is best, in order to squeeze the tip between the mast's lattice, and pull the wire bit by bit towards the top. After the wire has some some space inside the mast, the light bulb can be further extracted. In first stage, this needs to be done with care until the wire that's not insulated is released from the tube. Then the whole brown wire needs to be extracted via this end (the 6229 replacement bulb comes complete with the wires - one long insulated and one short not insulated - just like the removed one). The red wire is actually soldered to the mast, and the electrical connectivity goes just up to the point where the bulb is inserted. The last picture shows the electrical connectivity between these points.
