Make your own DCC powered red tail lamp for your model railway brake vans.
In this video I fit a DCC powered red tail lamp to my N Gauge Peco Brake Van. But this will work for OO and HO scale also.
If you want to dim the tail lamp this can be achieved by using a higher value dropper resistor, I use a 2 K ohm resistor in the video.

Something so simple ends up as a scary thing for some people, thank you for the step by step guide as to how you did it. This will definitely get the grey cells working for many of us who think it is too complicated to even think about. Please keep sharing your DIY tips with us. Oh by the way don’t forget to tap the thumbs up and subscribe to the channel.

I put a tail light into the same brakevan using a length of fiber-optic cable. The LED is inside the van, the fiber runs horizontally into a tiny square of plasticard representing a tail lamp. Much dimmer than a SMD viewed directly! I'd like to develop it into a system where yeu can tap a magnet on the roof to turn the lamp on or off

@pjeaton58 13 дней назад

I did a OO scale brake van years ago with a 3mm red LED on normal analogue 12volt, with rectifier for reverse, 2 of rechargeable AAA batteries and charge limit and LED resistors for the current in and out of the batteries ! 😊 😊

Nice build, though very fiddly 😂. I do recommend to solder a resistor and reverse diode between the rectifier + and the capacitor + to limit the capacitor load current.

@LlanfordParkModelRailway 9 дней назад

Thanks😀. I did try and measure the capacitor inrush current, but the charge was so fast I couldn’t read it on my DVM .

Nice video, this is a simple and good solution for installing tail lights (and other lights) in model wagons. 👌😎👍 I have one note though*: Due to the fact that an electric motor (like the one in a locomotive) can generate a CEMF (Counter-ElectroMotive Force) that can be of considerably higher voltage than the power normally fed to the rail, it may be safer to use a capacitor rated for 25 volts instead of the 16 volt capacitor recommended here, this will minimize risk of capacitor leakage (or even explosion)❗*(see correction in my reply below)

@@4623620 Hi thanks for the comment. I worked on the basis that for DCC systems,(as opposed to DC), commercial solutions for stay alive capacitors commonly supply 16v capacitors. Also of course for DCC there is a decoder between the track rail supply and the motor. However these are only assumptions as I am not an expert.

@@LlanfordParkModelRailway Please forgive me, you are right, I did not realise it was for DCC, should have read your text (but I am a lazy dyslexic). Than I could have known I had to mention that my suggestion is for DC systems. 😳

Love the idea. For older stock running old style lamps it's great. I run 1980s to 1990s that would be flashing tail lamps. Could u make this system but add flashing ?

@LlanfordParkModelRailway 6 дней назад

It is possible but would need some more electronic components for the flashing circuit. For N scale the challenge is always fitting components into the space available

@stocktonjunction 6 дней назад

@LlanfordParkModelRailway very true. I model oo at the moment so space is not as much of an issue

@frankiechristians7813 5 дней назад

100µF 24V is better And I would have used the thin wires of the LED and brass strips for pickups You can buy wheels with one side conductive, so no need for conductive paint

@marshallman7608 10 дней назад

Only problem with this is its way too bright. I started on the footplate in 1980 still in the BR paraffin lamp era and the best you could hope for from a tail lamp, even a signal light is dull flickering glow.

@LlanfordParkModelRailway 10 дней назад

I do agree having run mine for a while. I started with a 1 K ohm resistor and that was far too bright, so as in the video changed to 2 k ohm resistor to lower the brightness. I would use an even higher value dropper resistor next time maybe 2.5 k ohm or even 3 k ohm’s

@marshallman7608 10 дней назад

The paraffin signal lights were really bad. North/north west of Edinburgh was predominantly semaphore signals back then. Being cautioned at night resulted in peering into the darkness to spot the signal. As one old driver used to say you have to find them before you can stop at them!
