TWIN HEADLIGHT RELAY NEW ERA 12 VOLT 12V NEW NLR-132 30A 30 AMPS
The site also includes some suggested circuit diagrams if you click on their different pages....
You can do these relays and also buy an upgrade kit to make the headlights H4 or Halogen - or some other flasher newer technology of headlight. I went up to H4 with relays and I am happy to leave it at that.
Kind Regards
Lionel
