Thread: Replacing "jewel" lights in speedo instrument

I've never replaced these, but I have had the speedos apart. I am pretty certain they are just pressed in, but if glued I would use superglue.

I am yet to actually open up the speedo and multi instrument, so just thinking ahead.ThanksJohn

They're held on with 'one way washers', easy to push on, hard to remove. It's easy to damage the jewel when removing..W.

Thanks guys, much appreciated.

I'm not sure if my one way washers are still there, I won't know until I take the instruments apart, hopefully this week.

At lease I know they need to be secured somehow, and if I can't find those washers, I might try some plastic tube or an o-ring on the inside to keep them in place.

Cheers,
John

Plastic tubing will work, I've done it in the past.
