240z Speedo' bulbs/lamps

[Graham Palmer]

Hi, in my '73 UK spec 240z, I found a dead bulb in a lamp holder hanging behind the speedo. On contorting to look behind the speedo, at the bottom of the speedo back casing, I see two lamp holder holes. One on the left (as the driver looks at it) is the handbrake/parking brake warning light...has a lamp occupying the hole and works fine.

The hole to the right
(as the driver looks at it), is empty..so I assume the 'loose' lamp should fit in there ?..but I have no idea what that lamp should indicate ...any one know ?...

(I have illumination on the speedo when I turn the lights on...although have no idea where that light is coming from !...)

cheers all

Those two bulbs are both illumination of the speedo. I expect it's a little dim on the side where the bulb isn't plugged in.

Hey thanks Jon, one of them is for the handbrake warning light....do you mean this one is dial illumination ?...tx

so.. high beam + illumination at the top and handbrake and illumination at the bottom?

Thanks guys - that's really helpful

For easy identification the illumination bulbs have one wire and 'ground' through the body of the speedo.

Cheers Rob, confirmed as illumination
