Dual headlight w/switch

Played with the idea of making the bike dual headlight capable for awhile since it is dark when I leave for work, and I'd like some more visibility, especially with the recent deer activity that I've run into. Had a thought today: why not put a switch in there as well? So I did it, wired the right light to the left with a switch in between to turn it off just in case of problems or, because in the daytime I won't need both low beams. It works well, just wondering if anyone else had already thought of this.
 
Probably not the right way to do it mate.Going straight from light to light and you will get both high and low on the right light at the same time.

Better off doing BD43's mod or splicing into the left switched wire ,then Hi beam will go off when you when you dip the lights.
 
Just experimenting at this point, it's not permanent. It's more about the idea of flexibility, to be able to have both, or just one low beam if you desire.
 
Why would you only want one when you can have both on?

You would be more visisble with both headlights on at all times.

Maybe he likes people coming up to him always and saying "hey, one of your headlights is out." Leave him be. :)

You know...no one ever said that to me. I did do BD's headlight mod however. I LOVE it. It was so easy (once I resolved myself to actually remove things as instructions told me) and the part is beautifully made.

I don't really need both in the daytime though. I've also read the other threads where some members speculate about the reliability of the charging system under a heavier load. If you developed some kind of problem along the way, (Or wanted to use another power hungry accessory) it might help to be able to shut off the twin headlight mode with the flick of a switch. That was the basis for my idea.
 
I have toyed with this idea as I don't want to be constantly draining my battery, but there are times 2 headlights would be handy, but if I did it I would definately go the BD43 route, but add a switch.

I had that happen to me couple of times, but it did end up being a conversation starter, so it was not bad. I did, however, do the slightly modified version of BD's mod (I have future plans I wanted to accommodate for the lights) because I think it looks better with both on. There is some "unevenness" about having only one of them on as far as I am concern.

Not a bad idea, but you can do BD's mod with an additional switch as well. You can even use the cable from him if you would like to buy it, but, instead running it to the headlight, you can run it to your switch and connect other end of the switch to the headlight. Simple mod to a mod. :)
 
Finished the final product a few minutes ago, took a weatherproofed toggle switch and mounted it into the side cowling. Wired the green wire to the switch, then to the light. Looks good, works good, but it's a little dark to take pictures now, I will put them up tomorrow.

I never had any issue with the battery and I have additional auxillary lightings for my bike. LED license plate light and two 16pod auxillary running and brake lights, plus my stebel horn.

My bike is an '06 which was bought brand new in April of '07 and I'm still running my original stock battery. Surprising considering the extreme heat usually takes a toll on the batteries.

It's all about Seeinandbeinseen.

If you have both the High and Low beams on in that light, keep an eye on it, in case it starts melting the lens.

That's correct...you don't want the high and low filaments on at the same time.....bad for the lens...

I definitely recommend doing the BD43 headlight mod! It is neat and works great.

Also the OP said he did not need both lows on during the day? I dis-agree...the day time is just as important, as and additional light will make you more visible to the cagers that don't notice that there are motorcycles on the rode!

Just my $1.25;)

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.

Ahh, cool. I must have mis-understood your first post, I thought you meant you were wiring it directly to the left light (with a switch in the middle).

Glad it's all working great.
