Buffer Stop lights
« on: October 06, 2018, 04:41:12 PM »
I'm looking for some Buffer stop lights but the only ones i can find are the gaugemaster ones but they arent really what i'm looking for. Does anyone know of any others, ive had a look around and cant see any so thought i'd ask here.

British style? American?  European?

Very easy to make yourself, just get a standard buffer stop and some pre-wired red 0402 LEDs from ebay with suitable resistors for the voltage you're using.  Encase the back of the LED in a little epoxy or similar to create a lamp.

I'm looking more for the ones on top of a pole. I know in OO they are easily available but no one seems to do it in N. I do have someone who could do it for me but the lead time is quite long so it maybe i will have to have a go myself and see what happened. The only other option as i see it is to modify the gaugemaster ones so they run off a seperate supply rather than the track supply.

No problem, use those pre-wired ones I linked to above and run the wires through thin brass or plastic tube. At worst you might need to de-solder the resistor temporarily while you feed the wires through the tube.

If you use brass tube then you can use that for one side of the circuit and just pass one wire up through the inside, soldering one short length of LED wire to the top of the tube.

Have a go, you'll feel proud to have made them yourself!

I made the crossing lights in this photo using the brass tube and single wire method over 20 years ago.  Larger LEDs but the same idea. They're still working perfectly.

Those are really bright, did you add extra resistance to tone them down?

Cheers

Yes I would certainly add or change the resistors to taste!   For the abnormal load project I worked on in 2016 (and which was at TINGS again this year on the german modular layout) I used something like 4k6 resistors if I remember correctly., and at least 1k resistors on the LEDs which were being driven directly from the PIC processor at 5V.  I was aiming for around 2mA through the 0402 LEDs

If you can find a source of fibre optic cable you could light every buffer stop on your layout from one small red bulb :hmmm:
