I thought I saw that someone on the forum had a home-made fix for these flickering lights inside train cars, maybe using capacitors??? Looking for a solution I can make if anyone has a solution.
Thanks, Markk

Did you look at this thread? It's how to build LED lighting modules that will drive LED strips and offer flicker-free lighting.
GRJ's Original DIY Constant Current PAX Car Lighting Module Files
The modules are also available commercially.
For standard incandescent bulbs, I have run a small flexible wire from passenger car to car to have more than one pickup supplying the voltage. The wires connect in each car with wire nuts and I drilled a 1/16 inch hole each cars bulkheads at the bottom to accommodate the wires. These wires are not a problem as I usually run the same string of cars together and pickup three cars with two hands.

I'm all in for LED upgrades with John's regulated power supply. Solves the flickering and reduces load at the same time.

And prevents degradation of the DCS signal on the track as well. 
I have some passenger cars that have two bulbs and each bulb was powered by one of the pickup rollers. By connecting together the wires of the two pickup rollers, the flickering was eliminated.

also gunrunner led power supply's verses eliminating light bulbs current draw where Led's only use milliamps a real plus! Alan

so... am I to understand that my lazy method of installing AC tolerant LED strips straight into my passenger car could cause problems/interference for the 'automated' 3-rail choo-choo control systems?
I have nothing but conventional trains, but in the future I might could...

It depends on exactly what makes them AC tolerant. Anything that puts a capacitor across the input power has the potential to degrade the DCS signal.

10-4.
the ones I used are made to accept 12v AC or DC. they simply have a surface mount diode in-line with each segment of LEDs. i suppose this makes them 'unregulated' but they start at roughly 7~8 volts and put up with 18volts, but I imagine that if I was using any DCS/Control system the FULL brightness at 18v would send me shopping for those regulating units
I tried to order a few of these boards but I couldn't figure out how to do it. I set up an account but got no further. GRJ, what am I missing ??

Yes sir Bob. All my passenger cars and cabeese run with John's regulator modules. Perfect fix.
You just go to this page: LED Lighting Regulator, select the quantity and press the Add to card button.
