Are there any alternatives to the Allegro units for the Mk 1 which don't require any major changes? It's just the headlight unit itself I am thinking of - not all the mounting gubbins that go with it. What's available and the same size as the Allegro lights? Don't need sidelights but would prefer Halogens rather than the usual candles that come as standard.
I know that base model early Metro lamps are similar, as are Triumph Toledo. Are there any others? Triumph Acclaim maybe?
