if i where you id spend a fiver on a h4 bulb and just plug it in see how it looks, if it doesn't work then its no real loss.
I dont know why i couldn't get just bulbs to come out too well, i think a lot of it is the reflector is pretty faded and moreĀ white than silver.
the range on these isn't amazing i can see infront of me enough ish but compared to my spotlights the range is about half.
But they look cool and function well!
Worst case you can keep your h1 and just chuck on a spotlight
im half tempted to wire my spotlights up for country lane riding at speed so i can see further up the road
