Working rear oil lamps system - does anybody have info
« on: June 26, 2018, 03:41:15 pm »
I'd like to add working oil lamps to some of my coaches and brake vans for DC only, (DCC a definite 'NO' for me). Does anybody have a wiring diagram and components list for a mini LED to make a capacitor 'stay alive' system , i'm quite happy and well able to self make the axle pick ups.

Ive tried searching the forum but come up blank.

Hi Fred.
I found this which you may be able to adapt if you can fit a light source..............

This might work


Make c1 as large a value capacitor as you can physically fit,the higher the value the longer the led will stay lit without power, make sure its rated for at least 35v.The value of R2 depends on the led your using,but a 1 or 2k should be a good staring point.

I'm pretty sure there are some commercial tail light kits for N which use a button cell, they should last for ages and would avoid the drag of wheel pickups.

I seem to remember @Caz doing something along those lines
I'm not sure if life is passing me by, or trying to run me over.

Train Tech produce them but the downside is that they are £15 each or £20 if you want an additional output for carriage lighting.

As Malc says, I've fitted working tail lamps to all my rolling stock where needed, coaches, cct wagons, guards vans, etc and also on the loco's themselves (both front and back).  It is a lot easier for me as I'm DCC so power is always available.
Most are done with an LED and a bit of fibre optic, in the early days I used a standard LED + heatshrink tube and a bit of fibre optic but now I use the 0603 SMD LEDs.  They're fiddly to work with but you can get them now with leads already soldered on which helps if you're not good at soldering.

I must admit I now make use of the type with leads already fitted for the dual colour leds, red/warm white for steam loco tenders, red/green & red/yellow for shunt signals etc.  For steam loco headlamps I still use separate warm white and red LEDs as I fit them with a little handle so they look right on the front of the loco.  Below are a few examples.

Wow thats a nice can of worms ive tipped ip, i need to do some mire reading of the above to enable me to asbsorb the tech bits. May i ask Caz if you can give me ordering info for the bicolour Leds?
I run at MMRC n gauge layout which is DC, ive also a good selection of locos so DCC is not an option either at the club or for my collection as chip costs i just couldnt afford. I need to first work on the pickups then to figure out the ‘stay alive’ system. I also run an autocoach and flying banana. Im also working on LMS10000 which would benefit from lights.
Thanks again for the replies , please keep them coming.

If you search on eBay you should find the various option, here's a link to the bi-colour red/warm white ones.  For steam locos warm white is best but for newer stuff the bright white is better.

and Red/Green (for shunt signals etc)
