Bullet Terminal Sizes

Hey everyone,

I'm putting on a set of LED blinkers on my 78 KZ1000 LTD. I noticed that the original blinker wiring uses two smaller bullet connectors than usual for the running lights and blinkers, while the ground wire is the standard 3.9mm bullet. My new blinkers only have the 3.9mm connectors so I would like to try modifying the necessary wires to use the smaller bullets. I measured the bullet diameter to be about 2.5mm, but haven't found a replacement yet. I bought some "B1" male and "B2" female connectors, and those seem to be 3.9mm. Is there a standard size system for bullet connectors?

Here is a pic of the original blinker wires for reference.

The norm is 3.7mm or 4.9mm - it appears 2.5mm are used in RC models ??
