I have a broken wire on one of my gauge bulbs, the cold start one. I've had a good look around and am really struggling to find replacements. The originals come pre-terminated, it's not clear to me at all that the centre pin connection comes apart at all.

Are replacements with crimp terminals available? Could somebody please point me in the right direction? they're for screw in bulbs, the outer diameter is 1/2".

You could try somewhere like Autosparks online, but if you visiting any Classic shows there are often several stalls selling these.

Stafford vehicle components have a good selection.
