*Answer:

At 12 minutes past 2PM, all the lights will flicker together.

Interval at which all shall flicker together can be found by calculating LCM of all the interval values (8, 18 and 24 minutes).

LCM of 8, 18 and 24 minutes is 72 minutes = 1 hour and 12 minutes. Hence after 1 pm, next they will flicker together at 1 PM + 1 hour 12 minutes, that is 2:12 PM.
