After asking on here, and not getting anywhere, and emailing various HID companies who either couldn't help or didn't reply, I decided to find a fix for this myself after constantly forgetting my full beams were on. The fix is pretty straightforward, and just requires a 40A 12V Single pole normally open relay(which can be bought from Maplins among other places), some heatshrink tubing, a female spade connector, and a piece of wire. Firstly you need to jump 30 with 86 on the relay, so take the wire and crimp the spade connector onto it, then clip this into 30 before bending the connector down flat, this will enable the relay to fit the headlamp plug. You can then heatshrink over this connection to insulate it. Next you can strip the other end of the wire and loop it round to 87, it may seem a bodge but i just threaded the wire through the hole in the connector and then wrapped it around itself, before heatshrinking.(I did this over soldering or using connectors as it means it will still plug into the cars headlamp plug. Once you've done this its time to plug the relay in, its plugged into the drivers headlamp plug which should now be unused as your hid kit just uses the one, hence the problem with the missing dash light. You just need to take a little plastic off the cars headlamp plug to get the relay to plug in, I used some snips but you can use a knife, dremel, whatever: I then looped a cable tie through the back of the relay and round the headlamp plug just to ensure they stay together, but this is optional really. And now, we have a working full beam indicator:
