In the pursuit of perfection.... coming from a lexus owner

The MOT Certificate said "SRS light does not light up upon ignition"
Now there is an amber light with a driver with a seatbelt and an airbag to the side i.e for the side airbags, but no red SRS light.
Is this working? Can you take the bulb out or is it an LED?
I'm still waiting for Lexia 3 to arrive but any help in the meantime is appreciated.
