Indicators occasionally fail - Super 7 K-series, 2002

[wpqs]

I occasionally suffer from a failure of my Caterham’s indicators which can be fixed by switching on the hazards, rocking the relays, etc. The hazards are definitely not working as they should. The switch light is dim and the relay buzzes before coming to life, then the hazards start working again - strange! Perhaps fitting new relays for both hazards and indicators (numbers  3, 4 in the manual) might help. 

Caterham sell Micro relays - https://caterhamparts.co.uk/fuses-relays/4311-micro-relay.html  Are these any different to the standard sort of micro relays available at Halfords, etc? Can someone recommend a better brand?

Any suggestions about my intermittent indicator failure would be welcome too.

There's a well-described problem with the hazard light switch which affects both the hazard warning lights and the indicators, and it sounds like that.

You can try and improve the contacts inside the switch or replace the switch. 

There's also an explanation which leads (!) to a circuit modification which prevents recurrence.

Yes, replace the hazard light switch. You have already encountered the temporary solution of rocking it too & fro. 

As for the dash indicator, perhaps the lamp isn't fully in the housing?
