just been sent my relays and switches for my car.there are 2 relays 1 is a fl2h and the other is a fl2 now which 1 is used for the hazards and which for the indicators ???????
any help is always appreciated

I think you'll find that the FL2H is for the hazards.

They'll usually be printed with their ratings/function, though:

The FL2 should be marked as 21W x 2 +1 x 5W (ie. intended to drive two 21W indicator bulbs and a 5W tell-tale), or something similar.

The FL2H should be marked as 21W x 4 + 1 x 5W (ie. intended to drive four 21W indicator bulbs and a 5W tell-tale).

thank you for your help
