Thank you for viewing. This is interior lighting for Tomix models. All are LED interior lights. There are a total of 190 units. The breakdown is as follows: Granlight by Shoryu Railway: 110 white lights and 10 warm white lights, for a total of 120 units. 70 white interior lights made using commercially available chip LEDs, for a total of 190 units. All interior lights have plastic plates attached for easy installation in the vehicles. Granlight uses the included springs for installation. The self-made interior lights have copper plates already attached. Both products have flicker-prevention capacitors installed. These were removed from Tomix commuter trains. Although I wrote "for Tomix," with a little modification, they can probably be installed in vehicles from other manufacturers as well. If you have any questions, please comment.
