I know this is supposed to be an O Guage forum however, my current focus these days hase been doing some 2 rail HO modeling, mostly European trains. I recently got a passenger set of cars that the seller didn't know had bright led lighting installed from the PO. 1 of the cars didn't light, and since these were for vintage EU, I thought it best to remove them. The PO had cobbled a simple LED conversion using a MB6S (rectifier I think), capacitor and diode. The install was crude at best, using liquid tape around the bare wires; aother reason to remove. So now I'm looking to change and use a warm set of LED lighting. Given this is HO, I need something small. It looks like the LM2596 series of boards will work, provided I either get the one with the build in bridge or add one. Here is what I found.
Mini

With bridge rectifier
My concerns are
1. Sized to fit (I think any of these will fit)
2. Anti-flickering
3. Bridge to allow the lighting to work in reverse mode. Need for option 1 and 2.
Looking for recomendations, thanks !
