Thank you for viewing! This interior light is compatible with N-gauge conventional line limited express trains to regular cars. It uses COB tape light, and compared to genuine interior lights from Tomix and KATO, or other LED tape lights, it has a greater number of LEDs, illuminating the interior more evenly and brightly. Since it uses a 5V specification, it lights up from low speeds. A 1.2kΩ resistor is included, and the brightness is adjusted to resemble the actual train. The brightness will be even more stable when using constant lighting or PWM power units. To reduce flickering of the interior lights during operation, a 100μf electrolytic capacitor is attached. In reality, flickering is hardly noticeable. Please cut to match the length of your vehicle. Even when installed in commuter trains or vehicles with many windows, it shouldn't look out of place. The current collection plate has been processed to match the width of the vehicle for easy insertion. If it's still difficult to insert, remove the floorboard and insert it so that it contacts the current collection part under the floor. Attach it directly to the ceiling or attach it to the included plastic plate. Handle the electronic components on the interior light with care. Quantity: 10 sets (Includes 10 plastic plates with a thickness of 0.5mm and a length of approximately 13cm, matching the width of the interior light.) Size: (Emitting part) 12.5cm, Current collection plate approximately 5cm Manufacturer: KATO (Kato)
