Should only work when low on petrol....

Stick a jerry can in your car with some petrol in then drive it lower than empty. they vary a lot on when they come on. The tank capacity is 42 litres so if when you fill it up it is a lot less than that then you are not running it low enough for the light to come on.

No it will only come on once it's low enough.

My old 1994 super s didn't have a fuel light. it had the symbol there and i put a bulb in but it never lit up.
my SR (1996) lights up just after it goes into the red. perhaps the sensor is knackered?

A super s should have a fuel light, it was only the base base models that didn't have a fuel light.

And yer it won't come on at anytime but when you run low of fuel.

My 1994 Super S has a low fuel warning light, it seems to only come on once it's below the red on the fuel guage! They are adjustable with a lower or higher wattage bulb, just stick the lowest rated capless bulb you can find in there (they take the same size bulb as a front sidelight, in essence a '501' capless type bulb, but not exactly a '501' as that will be too high a wattage), 1.2w should light up earlier than the stock 3w bulb. You won't be able to LED convert these as the small amount of current that goes through will be enough to light the LED at all times! (made that mistake before!). The system works by decreasing resistance in the circuit as the tank runs dry, empty tank results in zero resistance and light on, hence when they come on, they light up gradually starting very dim and becoming brighter.

as i said i had the section there and put several bulbs in and it never lit leading me to believe the circuit was busted. still once it hits red you may aswell fill up anyways.
you don't need a bulb to tell you that really lol
