Looking for small connectors much like the ones ready made trains uses to connect their small beeps.

The ones used on the BEEP aren't that small, at least to me. What's the application?
I want to use them for led connectors for passenger lighting car to car.
thanks
You can buy much smaller connector sets on eBay for JST-PH 2-pin connectors, they'll make a much more compact tether for this purpose. Search for 50Sets Mini Micro JST 2.0mm PH 2-Pin Connector on eBay, lots of choices.
Thanks for the replies. Tstark

Wow those are big. There are many better options as John points to above.
In a word Carl... well, two words. Rolling Resistance. The center rollers contribute a lot to rolling resistance of passenger cars, removing many of them will really help with longer trains.
@gunrunnerjohn, I have no experience running long passenger trains, personally, so center roller pick-ups causing significant drag hadn't occurred to me. But I'll see if I can investigate it at my club where a couple of members run 10-13 pax cars, albeit 15" aluminum versions. Thanks for the explanation.
I've only done one with tethers, but it made a significant difference in drawbar pull resistance, almost cut it in half with eight MTH Premier cars and just rollers on the lead and trailing cars, all the others ran from the track power tether. I'm thinking my Aerotrain might get that treatment, the ten cars with the oddball trucks on the engine would benefit from less drag. For some reason, the Aerotrain cars have more drag, and I'm curious how much it would be reduced without the center rollers.
If you decide to do this, it's probably a good idea to add a PTC to each lead between the cars, in case one of the cars with rollers parks a roller on the outside track in a derailment.
Miniatronics has a line of 2, 3 & 4 pin miniature connectors. They are not inexpensive. I have used these for years and they are very reliable. Also, they are quite small and don't visually overload your setup.
I use those Bob, but they are pricey, so I don't always recommend them.
Also much quieter without center rollers. I want to run my electrical connection through the coupler, heck its big enough. all the way from locomotive. Then no rollers on cars
If your eliminating all but the pickups on the first and last car in the train don't forget to add PTC polyfuses between those two pickups. Thats a long buss wire to melt, likely to mess up more than just the wire. Think I would also use silicone superflex wire. The silicone insulation is difficult to melt. j

That's such a good idea that I suggested it yesterday.

This sounds neat for a battery application as well for those running deadrail. One battery to light your entire train.
Just got these in, this is the size I would be considering. These are 1.5mm pitch cable sets, and they're easily hidden. One cool way to hide them is the woven cable covers that would just expand over them after they're connected.
20 Set Micro JST 1.25 3-Pin Male&Female Connector plug with Wires Cables USA, eBay: 272521449002
They're $7 shipped free for the twenty sets, a lot cheaper than the Miniatronics cables. Not quite as small and neat, but affordable. For a 3-conductor male/female cable set from Miniatronics, I believe it's about $15 for ONE set.
You can cover these with the woven nylon cable cover, push it back to connect them and let it expand to cover the cable and connector. The cable cover comes in all diameters.
I use what I call aristo connectors which look just like the jst connectors in G scale because I run deadrail so no center rollers and they can be controlled remotely. From my experience with lithium battery run time would be quite long with leds
