I recently bought an order from EVAN Designs out of Colorado. An advertiser in the print magazine. ModelTrainSoftware.com
Fantastic website that helped narrow down what I wanted/needed. Many different options to power the lights, (AC, wall wart, transformer,battery etc). Bridge rectifier already installed for hassle free AC/DC installment.
Best of all was their prices. Very inexpensive.
Besides the myriad of house and loco lighting, I bought their “campfire” light kit, as well as the “welding” kit. Very cool.
