Chetlat island is the northern most inhabited island in Lakshadweep. There is a fortnightly passenger vessel service from Cochin to Chetlat. In addition the inter Island vessels also call on the island. The ships anchor at the southern anchorage about two NM from the island. The passengers are transported by machine boats from anchorage to Island. The Lighthouse is about one km from the Jetty.
There is no evidence of any light on the island earlier to the present one. The island was being identified by tall coconut palms. The existing G.I. trestle tower, supplied by M/s Kerala Electrical & Allied Industries, Cochin was erected during 1983-84 and the DA gas equipment from Madras Lighthouse workshop was installed which was commissioned in to service on the 14th May 1984. The MACE Radio beacon equipment was installed at the station during 1992 and the transmission was put on the air on 15th December1992. The Radio Beacon was however discontinued in April 2003 as per the decision taken at the meeting of CACL held in April 2000.
Subsequently the DA gas system was replaced by solar Battery operated electronic flasher ‘Jyoti Punj’ (JLWL) on 1stFebruary 1995. |
