I don't think I made myself clear in the first post. I wired the lights to each other for a few reasons:
1. To see if I liked the benefit of having two low beams
2. To see if it was possible to add a switch to the equation
I have a 30 mile commute to work, done mostly before the sun comes up, so I got a good test of the dual lights yesterday morning. I liked it and decided to make it permanent. I already had the necessary parts (wire, connectors, ect) so I just set about doing it similar to the bd43 way.
Here you can see where I wired it to the light with an angled connector. I ran it underneath and through the cowlings over to...
...The switch here. Moving the switch to the left turns the right low beam off, and moving it to the right turns it on. I simply drilled a hole in the plastic inserted the switch, and wired the terminals to it. The only downside I see here is that it could make the removal of that cowling harder. I then wired the switch with a pin at the end to the green wire from the wiring harness the same way bd43 did. Everything is routed cleanly and shrink taped as necessary.
To answer some other questions:
No, I don't think having an extra light in the blazing daylight is going to have an effect on a lazy driver. I like the visibility I get out of having both lows on for situations where it is impracticable for the high to be on.
No, only one filament at a time is on. I double checked this by experimenting with different wiring options before I made everything permanent.
I know that many have reported no problem, but I have seen several posts where members were concerned with battery drain. The addition of a switch might put some minds at ease. I also simply like the flexibility of it.
So there it is, for what it's worth. I like how it ended up, and if other members were hesitant about doing it, just know that it definately can be made to work with a switch. Some will like it, some won't, but that wasn't my goal at the start of this.
