It is illegal in some states for the passing lamps to operate when the headlight is on the high beam so HD wires it to conform.

 

Thanks Larry. You've been informative but how does the law define "passing lamps"? There are driving lights, fog lights, running lights and auxiliary lights. Are these all the same in the eyes of the law? I know not to turn on high beams in fog because they just illuminate the fog itself and not the road. Are they thinking these lights are only used in fog? I say everyone uses these lights on a motorcycle to be more visible to other drivers. And yes some use them to help illuminate the road but does anyone really keep these off all the time unless it is foggy? Even then if they shine so high as to illuminate fog then they should be allowed to be on with high beams. If they are to be below the fog then it shouldn't matter when they are on.

 

I bought the adapter harness from Kurykn that allows the spots to be on with the high beam. They can be turned on and off via the original switch. I recently replaced the OEM bulbs with Cyron LEDs. They were $70 for the pair and they are much brighter than the OEM bulbs. The Cyrons use Cree bulbs, and Cyrons part number:AB881-A6K

 

I bought the adapter from the HD dealer to turn on my Aux lights any time I want. I also adjusted the lights lower. I made the tool below by cutting and grinding a 9/16 deep socket. Thanks to Uncle Larry and others.

 

I waited until dark to do the final alignment of these lights and I'm glad I did. These things are much more directional than I thought. Not at all like fog lights. It's like having 3 head lights.
Back away from the garage I adjusted them on the garage door doing one light at a time.

 

Dave ... You are persistent. You managed to make it an all day project! Good job :>)

 

You are on it now, Dave.
Most folks totally overlook the spot adjustments.
I went with the Truck Lights (TLP7), left spot line slightly below the low beam line toward road center line, right spot slightly above low beam line and toward the right side of the road. At high beam with all three of these blazing, country roads are well lit at night, during the day you are much more visible. Can't beat it!
