Consider this eBay module, auction #: 122186424028, $1.39. Add a bridge rectifier in front of the input to convert the AC to DC, and you have constant intensity adjustable lighting with any input voltage.
Boost Buck DC adjustable step up down Converter XL6009 Module Voltage

Hi John,

Need your help!!! Please check the photo I've attached. I have an MTH passenger car that I put this boost buck board in (per your good advice) and tested it with my trusty 1035 transformer. I measured 12.5vac from the transformer before I connected the alligator clips to the power leads. (the black leads connect to the truck) the power from the truck goes to the bulb which I routed to my bridge rectifier.... then the output of course, goes to about a food of LED lighting strip. All was good until....the circuit and LED's began to get red hot. I shut the transformer immediately. Do I need a properly placed dropping resistor??? As usual, your help is greatly appreciated....
