Tal was asking about whether LED Headlights with now unused park/position socket - that is indeed a common problem that an unoccupied lamp socket will short out across the fitting and that is what blows the fuse.
If you TURNS are LED, then you want a CF13GL-02 Relay - note the whole label - JL vs GL has opposite polarity.
Just put that (CF13GL-02) in Ebay search and you'll find lots of sources in the UK
