So I'm riding in Bellingham, WA late last night. I turned onto a country road going about 45mph and switched on my High Beam. Not 10 seconds later it's suddenly totally dark. My headlight went out. Thankfully I was on a straightaway. I pull the clutch and shift down, pull to the side of the road and kill the engine. I find that my Low Beam is still working and start up again, turn around and start heading back to the city, a moment later the Low Beam goes out too. The LB going out right after the HB makes me think it must be a wiring issue rather than the bulb being at the end of its use.
This is a recently buttoned up Honda 350 Cafe, running one of THESE 55/60w Hi/lo H4 headlights that I modified to fit a 35/35w bulb by cutting a small provision where the bulb is seated. I did the entire wiring harness from scratch and so far have not had a blown fuse or any issues. I only ran a single fuse coming off of the + terminal of the battery. The charging system has been modified between the stator and R/R by combining the yellow and white wires from the stator to connect with the yellow from the R/R so the battery is also being charged when the headlight is off. This is a fairly new bulb, I've only been using it for a couple weeks and have riden with the light on for 50 miles or so with no noticeable issues.
So I'm trying to figure out why it blew. Did it act as a fuse and melt when drawing too much current? Could this be resolved by using a higher wattage bulb or a resistor?
