That looks very nice, I agree with your decision to scale down the rear lamp a bit, why not fit an LED rear bulb while you are at it, a lot brigher than the standard fillament item.

Have fitted LEDs front and rear on the KH and Morini, as I like to ride with the lights on these days, as you know LEDs dont put as much load on the ageing electrics.

I must have always been a wimp, never could get on with low bars
