Personally though I would investigate fully if there is any lighting coil on the engine as that would be much better.
Many thanks for the sound advice - was looking at nav lights & all-round white today as well as clamps to secure to my A (single) frame. Next step would be to wire them up and lead them to the powerpack under the console.

But as a longer term solution, will take your advice and have a detailed look at the engine for a lighting coil.
