I ran mine on the factory system for years with the factory rated fuse and never had anything close to an issue, I think they draw less power than a standard halogen, HID's on the other hand I had to run wire and relays with there own fuses, HID's on the factory harness will first blow the fuse then start to melt the fuse holder in the fuse box they draw a lot of power.Could you conduct a power draw test on those? I'm curious if they're actually 36w units. I have a pretty major distrust of aftermarket LED lights
