There are no factory fitted headlight relays.
If the low beam still works on the RHS and the high beam and the spot lights stopped working at the same time, More then likely you problem is with the contacts in the headlight switch.
They have a set of contacts for the LHS high beam and another set of contacts for the RHS high beam. You can pull the headlight switch apart and clean the contacts, you may also need to carefully adjust the contacts.
It is not a good idea to bridge the left and right high beam together, this will double the load going through the LHS switch contacts and the fuse.
If you are unable to repair the headlight switch you would be better off fitting relays.
