This is a mod I did on my Roadking that I have just finished on my new SEEG.
The headlight and the spot lights are powered off of the same fuse. It blew out on me one night on the interstate and I found myself running along at 75mph wondering what I was going to hit before I got stoped. I was just glad it didn`t happen on one of the mountain roads I ride  a lot.
On my new 05 the spot lights were powered when the low beam was on. There is a yellow wire that runs to the Headlight plug. This yellow wire splits into two yellow wires just inside the harness behind the plug. Its hard to see at first but one is smaller than the other. The small one is the one to cut because it feeds the spot lights. With that done I brought the power back to it from an Orange wire with a Red tracer , this is a seperate circut that feeds the Aux power switch on the dash. Its found as it runs into the big interconnect plug from the main harness . Its a Black plug that was near the right side of the radio. There is really nothing else on this circut from what I could see. By moving the spot lights to there own circut if I now loose a Headlight I still have a second set . The Spots will now also stay on with the high beams.

Having them fused separately is a good idea.  The problem (for me anyway) is elsewhere though.

While I actually like the idea of being able to decide for myself when the spots are on (high beam or low beam) my state feels differently.  Had a couple of different techs tell me at state inspection time that a bike will fail the mandated safety inspection if the spots don't go out when the headlight is on high beam.  

Since the inspection is a prerequisite for license plates here that makes it a problem.  And since the yellow (low beam) wire is the only thing in the harness that comes on when the low beams are on that makes it about the only choice to trigger the spots.  So now we're back on the same fuse.....   [smiley=nixweiss.gif]

If it will help you any, You still have control of spotlights with the panel switch by doing this rewire trick.

This is a great idea by splitting the power to the road lights DavidB, I will have to see if my sefb can be wired the same way. I think twolanerider is saying his state mandates legally that the roadlights automaticaly go off when the high beams are turned on.

Having them fused separately is a good idea.

I have a MS Word document I can email that gives step by step instructions for rewiring the passing lamps. I wrote the instrutions after making the mod to my 03 Ultra.  Just send me an email to mochrome@bellsouth.net if you'd like a copy

Here's a harness plug that I picked up on Ebay for My Road King:

You can do the same mod splitting the power feed twolanerider but use a relay using the aux power to the relay supply point and use the small yellow wire to the energizer point. Then the powers will be split and the function of the roadlights would be automatic. You could even put a hidden togle switch to overide the auto feature easily still using the relay...

After reading that initial post last evening the idea begun to bug me more and more.

thanks for the information...

With the toggle switches on the back side of the Road King nacelle that'd be no problem.  Waytek has switches of the size and type used in the Electra Glide inner fairing with variuos position options so I'm pretty sure a switch could be had to accomplish the same thing on the Glides.

I like the idea of separating the circuit just to allow independent control of when the aux lights are powered. As far as the safety aspect, granted it will add a layer of protection, but I have never had a headlamp fuze go out on me in over 20 years with over 150k miles on various FX and FL platforms. Bulbs, regulators, altenators, relays, and other assorted fuzes, but never a headlamp fuze. Is this a concern that is endemic to the glide or just another layer of just in case?

Thanks for taking the time to share.

[Twolanerider]

For me it seemed a "common sense" and "just in case" kind of thing.  After all, a bulb might fail (spot lamp or headlamp) in such a way that the element shorts even for a moment and then you blow the fuse.  If it were never going to happen then it wouldn't be fused to begin with.  Not that it's likely.  But, hey, it's just a fused circuit after all.  And since it is so easy to make the little change it's also one of those "why not?" kind of things.
