What type of connector does this block need?

[ferkh10]

Initially thought it would need a male bullet but I bought the smallest one available (red 4mm) and it was way too big for the hole at the top.

Maybe it needs a female connector? Each one is about 6mm wide.

Yoiu'll need to give us some context for that.
That is the connector from, attached to?
What sort of voltage is it? looks like 12v car stuff to me. If so, maybe you are better off asking here

We only deal with proper electrical stuff here

Indeed, it's a 12v block from an indicator stalk from a 1964 camper van.
Definitively nothing that'd kill me if wired up wrong
Cheers, will repost on the forum you linked

They are 4.7mm (actually I assume that's simply the metric size for 3/16th inch) and neither the red (4mm) nor blue (5mm) crimp bullets fit properly.

I find that blue crimp sockets will "do" if you squash them a bit, you'll struggle to open up a red one enough.

Try searching for mini or jaguar bullets.

cheers all, I got some blue 5mm female bullets and they were a little too big. Just pinched them up a little with the pliers and they worked fine.
Thanks all for the help
