Does your car have alky injection? GN's didn't come with fuel lights so someone put it in. Razors alky kit comes with an LED that goes in that spot to let you know when you're low on alky and it tends to flicker when running low.
A low fuel solid state board/light can be installed in our cars- i think it comes out of a riveria-if its not he alky-the board could be removed or replaced to put out the light.
