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 your 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 shortly after purchase, but these have been imported from a relatively recent production lot. Before shipping, we will always check the electrical conductivity and carefully package the product. Shipping costs are covered by us, and we ship anonymously. Although this is a new and unused item, please understand that it has been in someone's possession before, and we ask for no returns or exchanges. ※ 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 have transportation costs increased, but also, perhaps due to a labor shortage, there have been more shipping-related problems than before. Therefore, obtaining items from overseas as an individual has become considerably more time-consuming than before. We apologize to those who have requested items, but the series of tasks, such as researching product inventory and importing from overseas, may take longer than usual, or we may have to decline your request in some cases. Thank you for your understanding.
