Hy guys,
I need to replace my Morris 8 warning ignition light, in Manual says:
Lucas No.970; 2.5 Volts and 0.5 Watts.

But in ebay I find this:

I need a special lamp?
I found a 2.5V and 0.3A buld type E10 on this site:

Gonçalo,

This is the bulb you need. It is just expressed in a different way. If you divide the wattage (.5) by the voltage (12) you will get the .2A shown in the example you found. The early warning lights have a series resistor and use the 2.5 volt bulb and the later one don't and use a 12volt lamp

That's quite a find, if rather expensive. Until now all the supposedly reproduction items I'm aware of have left out the resistor wire and consequently employed a 6v bulb.

Take great care when fiddling with yours not to damage the resistor wire wound around the body of the lamp, which is very fragile. Also, be aware that despite the bulb having a screw thread it does not screw into the lamp—it's simply held in place by the red lens.

Be careful with some of the repro versions of this lamp; the resistor winding is purely cosmetic! So a 2.5v bulb won't last long!
