I have revamped the headlight upgrade kit and have added a new 3 relay system for controlling the headlamps. For the 3 way system a toggle switch needs to be mounted in the free space on the left handlebar switch cluster (photos are farther below).
The new 3 way kit gives you a total of 4 states for your lighting;
1) 1 low beam as set up at the factory for most countries
2) both low beams on. I have always supplied the headlight upgrade kits to be able to run both low beams but with the 3 way you can toggle them on/off.
3) high beams.
4) all beams off, there is a middle off position on the toggle switch which will allow you to have all your lamps off.
There are times when this can be beneficial.
A) Any time you are plogging along around 2000 RPM you are probably in a discharge state with your battery. You are pulling more current out than is going in. On a long slow off road trip it would be good to switch off the lights and conserve those 55 watts the low beam is pulling off. Over multiple days this could be the difference between starting up on a cold morning and maybe not starting up.
B) If you run electric clothing like I do or have accessories pulling off current I can tell you that you are probably running in a discharge state below about 4000 RPM. This would be another good time to save the 55 watts.
C) when starting it might be good to have the extra current during those first few seconds to minimize the chance of fouling a plug.
Obviously you need to use your head when switching off the lamps as the law is that modern bikes are to have at least one headlamp on when running. But on the freeway during the daytime or off in the sticks, who's to know?
The 3 way kit is available separately for $135 or you can upgrade the starter/headlight kit to this 3 way module for the additional $55. For value for the dollar evaluation purposes, the Bosch relays alone retail for about $25 USD each (but of course I buy them in bulk at wholesale).

2007) - Now supplied with Bosch Micro relays. Kit is half the size, seals better, mounts the same way. |
| I originally designed these headlight upgrade kits to be modular and they were 2 piece kits. There are too many different motorcycle specifications (length to headlamps, battery mounting position etc.) to allow for the modular theme so I now make these up as purpose built for a specific bike. That means they are now one piece and sealed up as shown above.
All A/C kits now use Bosch relays as they are sealed units, other makes have seams. I then completely seal the circuit for maximum moisture/corrosion protection. The standard A/C kit looks the same as above but has 2 relays instead of 3. |

 |
| This is the new recommended mounting system/position. The X made by the tiewraps holds the relay pack securely in place. There are no headlamp clearance issues. |

 |
| Both the original and the new 3-way kits now come with one fuse for all relays. The cost & time to build to use 2 hand-made fuse holders was going to make me have to raise the prices and it was somewhat of an overkill anyhow. Both kits come with the leads long enough to reach the back of the battery tray so no matter what battery you ever buy you will be good to go. There is plenty of room to tuck the extra 6 inches of lead away if your terminals are in front as mine are. I have had 3 batteries in my bike and each has had the terminals in a different place/orientation. |
|
|
 |
| The leads lay right along the frame rail. If your battery leads are opposite mine then just run the lead on the other frame rail and it will reach whatever orientation of terminals you have. |

 |
| MK II A/C kit and 3 way kit have these for power/ground. |

|
 |
| I was able to source some flag terminals and plastic housing for the MKII and 3 way kits. |
