I'm hoping somebody can throw out some useful suggestions for me. I've bought a couple of LED headlights that I was going to mount side by side. The plan was to wire things up so both are powered for high beam and one for low beam. They have a two wire cable, positive and negative. It turns out that they are set up internally so that when power is first applied they light up bright, flash the power and they dim, flash it again and they blink. I really have no use for the blinking feature at all though I have had headlight modulators on bikes in the past. What I'd really like to do is just disable both the dim feature and the blinking feature and go with Plan "A" and light two or one for high and low beam. Since it's most likely controlled by a chip of some kind there probably isn't any way to disable it.
If I can't disable the built in functions I guess Plan "B" would be to use both lights together wired though a momentary contact, normally closed switch. Bump it once and you'd go to dim, then when you want to go back to high beam you have to remember to bump the button twice to skip over the flashing function. This would be a relatively easy fix, but doing that wouldn't allow for use of the high beam indicator light in my DanMoto digital dash.
Have you opened up the lights? If there is a controller in there, and all you want is the lights to be on or off, then just bypass the controller. Make sure your not bypassing the resisters or voltage regulator that drop the voltage. Led's only need about 2-3 volts, so depending on how they are connected together there is most likely a resister in series.

No, but when I get a couple of minutes I'll take it apart and snap a pix.
I may be ok w/ things. I was playing w/ it again last night w/ it plugged into a 12v power supply. As said earlier, if I applied power I got bright, break the power and apply again it's dimmer and then do it again and it flashes. I also noticed that if I just plugged and unplugged the power supply it always came back on at the first step, bright. Perhaps if I just hook them up as stated above; one light for low beam and both for high, they would pretty much stay on the high setting... Also it occurs that a hook up something like that would probably require a diode somewhere in the line to keep the second light from powering up along w/ the low beam. (?)
They're suppose to be 125 watt/3000 lumens/6000-7000k color temp, +/- 200 yd range actual draw 15 watt
suppose to be usable a headlights, fog lights, running lights. My hope is to have one aimed a little lower and slightly to the right as a low beam and then have them both light on high with the second one aimed right out in front.
Have you tried them out yet? How well do they work? For a single LED of that size, I would be very surprised to see that kind of output.
Anyway... the reason I asked was because I have a few 3W LED headlights that I'm planning to use as running lights and they might bypass a lot of the issues you're facing. That was assuming you didn't have plans to use them as headlights.

For what I'm doing I'm sure they'll be fine, light wise, as headlights. I've had them powered up w/ a 12v power supply and they are plenty bright. There isn't much chance the little beast (and I) will be out after dark much but even if that were to happen there's more than enough light there to get home safely. Mostly in this case it'll be more a matter of being seen rather than seeing and there will be enough light being put out that they'll see me. Of course we all know how people in cages "see" motorcycles, you have to pretty much assume you are invisible when you ride anyway.
I have seen those lights in person. Imagine two high powered led flashlights strapped to the front of your bike. Not very good at all the beam is very thin and no light to the sides.
Actually thinking about it more led flashlights have the same modes. So what they probably did is take the flashlight internals and placed them in a "motorcyle" light housing. I have seen people remove the different modes on the flashlights so it is possible.
Like I said above they'll be fine for this build, it won't be out after dark much. And, if it doesn't work out I can change them out for something else. I've had these on w/ a power supply and they are very much more capable than a LED flashlight by far.
Yeah, if I need to I can do that. The things are pretty thick, kinna like the ultimate "coke bottle bottom glasses" but that's so they take the light put out by that little LED and magnify it into a decent sized beam.
