'ignoring all the red lights' is the definition.
I can't judge whether this defines the answer.

'and going to any lengths' is the wordplay.
I cannot quite see how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
'to' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
