Interior Lights Easy, Reliable & Low Cost - Detailed step-by-step tutorial

Very nice video, thanks. One comment though: @3:19 and @4:39 the power pick-up spring IMHO should be placed in between the axle and the boogie, rather than under the axle as it is shown here. You remove simply one of the wheels, then insert the pick up spiring and then you refit the wheels. Thus the wheels keep the spring in position. You do not need any glue.

[@klaus9909]

Hey Martin, Great video - as always. Just one addition to the circuit. If you have a number of these lit cars running and switch on your layout all capacitors want to charge with the highest possible power available. Your digital system will see this as a short circuit and will turn of power straight away. To prevent this you have to put in a charging resistor to limit the power consumed while charging the capacitor. This resistor is put between the positive pole of the rectifier to the capacitor. Usually a 100 Ohm resistor is enough. Cheers, Klaus

[@johntavish8750]

Would you need a special type of resistor? Also, is there a diagram of this wiring somewhere? I'm new to this. Thanks.

Hello, when you glue some passengers with fastsetglue, do not close the car immediatly. If you do, some emanations from the glue will change the color of the plastic windows... (that becomes yellow ...personnal experience...) let the car open a night and that will be OK. Thank you for your beatutiful tutorials ! Regards Pascal

[@eentoffenaam]

Pascal Keller True, also my experience. I found that glue, used for foto’s works just as well to glue passengers in the cars. And it is easier to remove the glue if you want to change it later on.

[@2H80vids]

Good tip, thank you.👌👍

[@2H80vids]

@@eentoffenaam Another good tip, thank you too.👍👌

[@nepomucen111]

If you have such emanations from glue you can try to put some glossy garnish on them (thin layer). It can help. You can check with just water, if it would help (putting some water on that window should help for a moment - if it does, than gloss garnish will also help - permanently).

Super was es heute zu Tage für Möglichkeiten von den Herstellern gibt das hatte ich in den 70er 80er nicht, naja das ist halt der Fortschritt 👍 ich benutze auch immer Sekundenkleber um die LEDs zu befestigen denn der tape löst sich nach einiger Zeit.

[@stormbowman7148]

If you use the Noch "Hin und Weg-Kleber" you can move the passengers around, and it is also strong enough to keep the light strip in place. The benefit is that you can remove everything and no permanent damage is done to the coach.

Hi Martin, Thanks for your great tutorials. Helps me advance quick in this hobby. After ordering (and waiting for delivery) the components, I already equiped two cars with interior lights. Works perfect! Kind regards, Maurits

[@shanestrains4724]

This actually works! I've used this method to add interior lighting to a couple of caboose on my layout. I used 2 3v nano LED's with a 420 ohm resistor on each LED. Works like a charm. I don't have any issues powering up the layout as some suggested might happen either without an additional resistor on the capacitor. The hardest part was getting my Trueline Caboose apart and back together again. Thanks for posting the video brother. 👍

[@magnificus8581]

Thank you for also showing how to do it on 2 rail systems!

[@allenkotlan3606]

Beautiful and you make it look so easy. I'm excited to get to that task as soon as I can - so many other things to build.

[@steveksi]

Nice. The more expensive LED strips have 3M tape on the back. I have used these in many many Jewelry displays over the years, NEVER had any come loose. It is important to clean the surface with Alcohol or the likes to clean off the grease. I generally mount them on Aluminium Flat bar, usually 10mm wide by 1.5mm thick. for commercial applications, for cooling.

[@gandalaress]

With a cheap Functional-Decoder (TAMS for e.g.) there's no need to use resistors to reduce brightness, just programm it. And it'd be switchable. Also the rear-lights could follow the direction and turn automatically off while driving backwards.

[@mikewest3108]

Really good looking. Perhaps winding the wire routed underneath the wheels into a tight coils like old telephone cords would resolve the problem of slack in the wires and still allow trucks to move freely.

Good video! I found a similar recipe for lighting a few years ago on the internet. I use double-sided foam tape between the LED light strip and the roof because the LED light strip can generate some heat => i don't want the roof plastic to melt or get soft if it gets hot.

Hi Marklin. I've recently gotten in to model building and painting with a strong focus (currently) on Star Wars models. I'm a recent subscriber and your videos are so fun to watch and learn from and that's predominantly because of your infectious energy, your presentation, and obvious love for the medium. I'm about to start designing my first (small) diorama for an AT-ST walker that I built, painted, and weathered recently and will be using techniques from your videos to help develop the project. Thanks for being a little source of happiness and positive energy in these strange and crazy pandemic times. :-)

[@edmundmaier2273]

Great tutorial Martin!! Could you please tell me what is the model number for the pick-up shoe which is not shown in the video? Do I need only one spring and pick-up shoe for the entire passenger cars? With the couplings the positive is fed to all other passenger cars and on each passenger car would I need to mount a spring, bridge rectifier, capacitor, resistors and led strips? Could you please give details on the bridge rectifier which is required? Million Thanks!

Cool. One thing one might consider as an improvement is to control the LEDs with a microcontroller and use PWM instead of resistors. This will reduce power consumption and increase the time car lights survive an outage. It would also enable the ability to use blinking taillights. Adding an ambient light detector or even a decoder would make it even more fun.

[@jamesfisher4326]

The circuit as described will draw less than 1 ma once the capacitor is charged. It hardly seems that it is any real advantage to use more sophisticated electronics to improve efficiency. It might be an improvement to add a 100 to 500 ohm resistor before the capacitor to reduce the inrush current when power is turned on.

Hi, you can put the ground contact under the wheels. With this method, there is no glue. It's more practical when u need to change the wheels or the contacts.

[@marklinofsweden]

Hi! No, assembling spring contacts under the wheels will restrict movement of the cable coming from the conductive coupling. I can’t recommend that.

[@nepomucen111]

@@marklinofsweden You should put that cable into the car, put (through the toilet) up under the roof and have no cables under the car. The same for cable from buggy contact. That way you will not block the movement of buggy at all. With your solution the movement can be limited.

[@antoinebesnehard]

Hi Martin! Nice video, thanks. Just a little suggestion: instead of glueing the copper springs to take the current under the bogie, why not first take the wheels of, then place the springs without glueing and put the wheels back? That's what I do on all my (2 rails DCC) cars and it works perfect. Since I don't have Marklin rolling stock, I use generic metal springs I buy on eBay, but the principle is the same I guess.

[@kjellmortenklevsand2088]

Very nice and inspiring !!

[@Kapparie]

4:30 you should infact install the contact spring "fingers" under the wheelaxles, not above them (seen from bottomview perspective) and then you don't need glue at all, because it will keep the spring in place by the wheelaxles pressing to the bottom of the bogie.

[@marklinofsweden]

Hi. Thanks for great video! I’ll start doing all my wagons. My question, to reduce inrush current, do I need to add 100 Ohm resistor between input of bridge and ground wire? Or, between + side of bridge and capacitor? Which is better? Can you help? Regards.

[@danielvanmieghem1091]

Nice job there, again ... Perhaps if I can add a hint for future projects, I would suggest using a function decoder for digital layouts, so you can switch the lights on/off using the digital controller. That works wonders and in some cases even adds possibility to dim the lights and switch rear signal lights separately. Great stuff, man !

[@roulernbleu4532]

That's what I was wondering. The track is DCC right? I have digital Trix and I don't get anything out from the passenger coach lights without decoder. 🧐

[@yevgenykushnir1200]

Martin, thank you for this. I have rewatched this multiple times in recent months, and this inspired a coach lighting project of my own (modern European 2-rail, mostly Roco). Question....how did you determine the 10K Ohm as the resistor value? I know the basic formula for resistance, but what are the values?? I assume Marklin MFX puts the same voltage on the rails as other DCC systems (28 volts) and a warm white LED is rated at 0.0025 Amps (I think)....correct? I'm currently trying 12-20V DC, and with a 4.7K ohm resistor, the light seems too dim (and only really seen in complete darkness). Another question, how do you get the capacitor to keep the lights on for 10-12 seconds? I'm using 1000 or 2200 mF 25V capacitors, and the lights gradually die off over 5-7 seconds. Logically, they should stay on for longer than yours. Is there a specific to wire them into the circuit? Have been greatly enjoying your videos over the course of the pandemic! Looking forward to becoming a Patreon soon!! :)

[@the_clockwork_jackass6897]

I think it may be cool to have certain areas that are rocky or rundown where lighted cars would intentionally flicker. I thought you might be able to do this with a microswitch (normally closed) in the car and a piece of piano wire (very stiff) bent into a corrugated/serrated form that would hit the microswitch and cause the lights to pulse on and off making the appearance of a bad connection due to rust and dirt buildup

[@timfaszbender7226]

Nice video but 2 things I don't understand. 1: you glue the spring in the boogie, but when you take out the wheels of the boogie, you can put the spring in the boogie and then put the wheels back. No glue is needed than. The spring fit in the boogie and with the weels above, the spring can't move. 2: both side's of the car have a hole, but you decide to pull the cables under the coach. But isn't it better to put the cables through the closest boogie hole and pull the cable under the interior of the car. The cables are then completely invisible. Marklin has also the sets 72020 and 72021. With the parts in the set you don't have to solder a wire on the koppeling

[@marklinofsweden]

Hi Tim! In response to your questions: 1) Ok. Yes, I realise that is the purpose. However. Mounting under wheel axels restrict the movement of the cables coming from the conductive coupling. 2) In most cars there are no, and then I mean NO room for a cable, not even a 0.5mm cable. If you root the cable through the first hole, you will not be able to snap the car together again. Okay.. This car may work, but any better detailed Märklin car, Brawa, Roco or other brand will for sure require cable rooting under the car.

[@marklinofsweden]

The price of the set is x10 the price for the entire installation described in the video + leaves you with flickering light och low overall performance.

Those cars look great. I will have to see if I can find a way to do that with my Walther's Classic Heavyweights set. They already have the contacts installed and light kits that can be bought but I'm not impressed with those, only thing is the roof is what is removable from the car before the interiors so having to find a way to suspend them might be tricky.
