Hope this question will make sense..as I have mentioned, I'm useless on the electronics side, and my brother-in-law helps me out with it. However when we first got the railway running 10 years ago we found some other guys to do all the essentials for what was then an all-analogue railway, including some station platform lamps. For these, they used connectors of the type you see in the photo (so that the lamps could be removed in winter). Gradually however the lamps got broken in bad weather anyway, but I am going to give them another try. However we don't seem to have the other ends of that connector type, and they are also quite bulky, they seem to be audio connectors. So my question is, could anybody recommend some similar connectors for this purpose, which might also be less bulky than these things? I thank you..
