5-3/4 inch Cibie in a cheapo Bates style shell. 1st run down some back roads this evening. "Oh Yes" most illuminating. I shall buy the second one now. Cheap solution, about £50 all in per side. Just need to run some heavy duty wire up and splice in a relay. What are regarded as the best focussed 60/55W H4 bulbs available now? It is still tempting to add a couple of small H2 spots under the main units for truly horrible wet dark journeys. Would a Bandit genny cope with 240 watts of high beam?? IIRC the output is around 400w total but not sure.
