Thank you for viewing. This is an introduction to the marklin bulb (19V) for analog vehicles, bubble 600100 (old product number: 60010). This product was imported directly from Germany and has been checked for bulb failure. A compatibility chart for analog vehicles (not for digital) is shown in the second photo. Please use it as a reference, and confirm the final compatibility in the vehicle's instruction manual. This is a screw-in type bulb, not a plug-in type. Some bulbs deteriorate due to long-term storage and may burn out in a short period after purchase, but this product has been imported from a lot that has not been manufactured for a long time. Before shipping the product, we will always check the power and carefully pack it. Shipping costs are covered by us and will be sent anonymously. Although it is a new and unused item, please understand that it has been in someone's hands once, and we ask for no returns or claims. ※ We also accept questions in English and German. (If you have any question in English or German, please feel free to ask) Recently, not only the rise in transportation costs but also the shortage of manpower seems to have caused more troubles associated with transportation than before, so it has become quite troublesome to obtain products from overseas by individuals compared to before. We apologize to those who have requested products, but the series of operations such as researching product inventory and importing from overseas may take more time than before, or we may have to decline in some cases, so please understand.
