Yes get a dual white / red headlight. Wilkinsons do one for £10 which works well. I once took off from Santa Maria at night in a Seneca, just after take of and just as I entered the low cloud / fog the instrument lights went off and I couldn't see the AI very well which was....interesting! Still the landing lights reflecting off the cloud just gave enough light, but now I always have a backup!
Actually I have never done a NQ, but have flown a lot at night under the FAA and to be honest I didn't really notice much difference with landings etc...I'd never try to dead reckon at night and would either use radio nav or GPS as primary nav.
