And the rascals have 'highjacked' MY thread to have their fight on! And I am still waiting for an answer to my original question!
H3 were to be for spotlights which I posted about on another thread, but it was suggested that 2x55w halogen spots may be a bit too much for the C5, so I was enquiring as to H3 LEDs and the possibility of H4 LED and use perhaps H3 Halogen........confused? .......I am!
