Thank you for viewing. This is a listing for Märklin HO analog car bulbs, model 600150 (old product number: 60015). These were purchased directly from Germany and have been checked for functionality. This type of bulb is likely the most common for analog cars (not for digital). A compatibility chart is included in the third photo, please use it as a reference, and confirm compatibility in your vehicle's instruction manual. This is a plug-in type. (Insert into the socket groove and rotate 90 degrees) Please note that it is not a screw-in type. Some bulbs may deteriorate due to long-term storage and may burn out shortly after purchase, but these were imported from a relatively recent production lot. Before shipping, each item will be tested for functionality and carefully packaged. Shipping costs are covered by the seller and will be sent anonymously. Although these are new and unused, please understand that they have been handled by a person and are sold as-is, non-returnable, and non-refundable. HO Marklin Märklin maerklin
