During Midsummer Eve, a light show (6)

I believe the answer is:

reveal

'show' is the definition.
('reveal' can be a synonym of 'show')

'during midsummer eve a light' is the wordplay.
'during' indicates a hidden word.
'REVEAL' can be found hidden inside 'midsummer eve a light'.

(Other definitions for reveal that I've seen before include "Spill beans" , "Remove cover or expose to view" , "Expose, remove covering" , "Make known to others" , "Open up" .)

I've seen this clue in The Independent.
