I've lost the indicator relay noise!

[Mags]

I had to replace the OG indicator relay, the big blue one that makes the lovely click-clunk noise when the indicators are on. The modern replacement is close to silent I have accidentally left my indicators on a few times and I miss that "period" noise that only the Bus makes. Is there a suitable replacement or does anyone refurb the old ones?

Thanks
