I would think any low wattage 12 volt light would be OK. the current from the globe is an exciter for the alternator
they will actually work without the light on the dash once the engine revs

G'day Pete,
An alternator light needs to have some resistance to excite the charge circuit.
So, the answer is yes, any pilot light will work.  BUT (always a but isn't there  ;))
if you use an LED light you will need to wire in a resistor as LED lights have very little resistance.

Cheers
Neil

if your referring to the chrome bezel / red LED, then that is what im using on my Gemini for alternator light, it seems to work fine for a commodore alternator.
No matter what the question is, the answer is always more horsepower!
