Dear Nitro North Norway
I did not first respond since I thought you had added just the H.I.D. bulbs and not the whole headlamp assemblies as I did. Just replacing the bulbs has been an issue for some and did require some modifications to work. As far as adding the complete headlamp assemblies as I did they should be just plug-n-play. Same wiring harness and same plugs using the same switch! NO MODIFICATIONS ARE REQUIRED (at least on the Nitro USA vehicles).
It sounds like you may have a overload. If you unplug one lamp when in operation does this allow the other lamp to stay on and operate correctly?
