Simple solution and a bargain(?) at about �110.

Buy 1 relay solution of your choice.

Choose spot lights which are similar size to expensive (but probably very good...) Solstice lights. I chose http://www.ebay.co.uk/itm/400587348429 and can recommend them, reasonable quality for the price.

Wired into main beam via relay and I can now see in the dark! Position of lights protects them from scrapes and still allows for a high up mudguard.

Hope it helps someone,
