Lights taking 50 current amps (5)
I believe the answer is:
lamps
'lights' is the definition.
(lamp is a kind of light)
'50 current amps' is the wordplay.
I cannot quite understand how this works, but
'50' could be 'l' (Roman numeral) and 'l' is present in the answer.
'current' could be 'amps' (I've seen this before) and 'amps' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'taking' acts as a link.
Can you help me to learn more?
(Other definitions for lamps that I've seen before include "Devices for giving light" , "light fittings" , "Lights" .)
