what does the gas light symbol look like

What is your question?

I had my emissions control done and as soon as I drove off my gas light came on. It has been on for the last 3 weeks and no one can explain why, new gas cap, I always tighten until it clicks. I want to be sure that it is in fact my gas light symbol and not something else. could you please send me a picture of the gas light symbol? Thank you. It is a 2003 Lexus LX470.
