Ok I've resurrected my 1980 Honda CT 110, been using it for transportation back and forth to work. But the headlight really sucks, the bike has a 6V magneto system, the light actually dims at idle, and is not very bright at full power. I want to build a LED replacement, but I have a couple of questions I hope you experts can answer.
1. How well do LEDs handle power surges and spikes? or will a boost fix this? Anyone got a good circuit?
2. Suggestions on fitting a light in the headlight spot and making it look "normal" and focused
3. What would be the best for this 1-2 high power 50W, or several of the newer lower wattage lights?
I have had similar plans for a few bikes, but I have not come up with a good way to mimic the E-codes low beam beampattern. The ordinary "round spot" of light from LEDs just isn't an acceptable low beam for me.
As a compromise I am keeping the standard headlight on one bike (12V 45/40W Ba20d), and I am adding a pair of XR-E Q5 as auxillary lights to be used together with the high beam.
About your bike: Before you toss away your lamp, do check if it really works as it is supposed to. In a 28 year old 6V system I would not be suprised if 1V or more gets lost in the wiring, and that kills alot of light. You may also have the possibility to use a slightly higher wattage bulb for more light.
