Residents of Block 37 at Circuit Road have been plagued by blackouts for four nights since Nov 3.
Sources said that the corridor lights of the HDB block did not turn on at the times they were supposed to in the evening. The lifts were still in working order.
There was a period of time (Nov 5) some residents experienced no electricity in their HDB flat for about two hours.
The resident said she left her flat at around 7pm after the electricity was down. She only returned home at around 9pm after power came back on.
It is said that the technicians have been called in several times to resolve the problem but the blackouts still continue.
