Warning Lamp not Lighting

[boneyd]

Hi people. I have IS Lexus from past 1 year. These days I am facing a small trouble in the car. The warning lamp does not light when the ignition is on and the engine is off. What can be the possible cause of the same?

I think the fuse must have blown. You can check the fuse. If the fuse is working fine, then it can be bad wiring connection or defective regulator or relay.
