Can mean many things, automatic gearbox, emissions problems and if it flashes, it is an immobilizer fault. The car can be driven, if running ok but the engine management system should be checked ASAP. You will need EOBD diagnostic equipment to find cause. vauxhall can check this 4 u but it will cost u £47 unfortuanely but 4 that price u can get the diagnostic reader ur self the port is under the ash tray or the cover below the hand brakeRAC.htm">http://www.argos.co.uk/static/Product/partNumber/7402742/Trail/searchtext>RAC.htm
It might be a problem with a relay, have them taken off and tested each one of them, are u hearing a "click" sound when u turn that switch on the ignition? if so, it could be your relay, hope this helps
take care
