FIREFLY FFmed, N Scale End of Train Fred LED, Medium Extension

I bought two more. Easy to install, work great! Love it.

These things are awesome! If you can change a lightbulb, you can install these. So much better than flipping a battery micro switch buried in an n scale boxcar. I have 3 already and I will be back! High quality product from a high quality seller. Just my 2 Pennies.

The media could not be loaded.  It’s a nice idea but after about 10 minutes of run time one wheel pick up started falling off and it stopped working. I also noticed that the wheel pick ups cause the wheels to drag Most of the time rather then freely roll as they rub the inner part of wheels. I Did managed to glue the pick up back in place but the dragging wheels make it useless other then static display for now. Looking to convert it to battery powered.Update: I removed the electrical pick ups and converted to battery with a small 12volt battery and now it’s good. I noticed this is really easy to make it’s just two leds with one being a flashing led that’s larger and hidden and the other a red nano type led mounted to the coupler. The flashing led is wired in series. Simple easy to make so I made four for a cost of $8.

Great product, fit like a glove, looks/operates great.

Fairly difficult to install, especially on a Kato Double-stack Well Car.The real problem is after installation the Brass Contacts on Trucks that brush up against the Wheels cause SO much Drag that it Derails!!Tried everything to get it to work..Finally had to cobble something up to get original Trucks back on (after I modified the hell out of them to make Fred work!)There goes $25...Ugh..It looked great on parked Train though!

Worked perfect. Have a free on the end of my coal train.
