led

I'm a little stuck... Click here to teach me more about this clue!

This clue could be a double definition.

'guided' is the first definition.
('lead' can be a synonym of 'guide')

'a little electric light' is the second definition.
'led' can be an answer for 'light' (light-emitting diode). I'm not sure about the 'a little electric' bit.

'by' acts as a link.

Can you help me to learn more?

(Other definitions for led that I've seen before include "Something emitting light" , "Went in advance of others" , "Shown the way" , "Took by the hand and showed the way" , "Guided; small light" .)

I've seen this clue in the Evening Standard.
