Fo some reason the inner headlights in the bonnet were unplugged, have since plugged them back to where they appeared to be disconnected from, however they only come on hi beam, is that correct of should the be on with when the main headlights are on low beam as well.
Just some extraneous comments, as I’m wont to do, mainly to assist those chasing extra knowledge about their cars to help sort out problems.
The additional pair is exclusively high beam. Having four low beam lamps is probably illegal. You can check by peering through the lens (sealed beam) where you might be able to see a single filament versus a dual filament in the primary lights. You can also confirm at the lamp connectors where there should be only two contacts for the additional lamps and three for the primary ones, one contact on each being an earth return. The high beam cable colour code on all four lamps should be the same.
Being an extraneous kind of guy, I will add that the seven-inch outers, particularly if good quality Euro spec, are more than adequate. On my S1 XJ6 I substituted long-range driving lights for the inners, switched separately.
The inner headlights on the 420g and Mk10 are definitively high beam only as is shown the circuit diagram. Blue with a white tracer is the wire colour if I remember correctly.
