Would you happen to have a part or model number for the Evitek LED light?
I tried, the stumbling block was the retaining clip. The big heat sink cooling fan portion of the bulb interferes too much with getting that clip hooked up properly. I ended up going back and installing the H4 halogen.Havent seen the back of a C10 headlight but I reckon from your description the ones I used on the C14 would get around this as the heat sink is removable for getting the clips on
