Replacement relay

I'm fairly sure that I have a bad relay. The problem is that I can't find any new Hella 01RA001 4ra940010 relays. I'm not an electrician so what is an alternative replacement part that wont fry my Rocket? I don't want to use used relays.

Thanks,

L.C.

If you take it down to your local auto parts store they will have an equivalent one for like $5.
