Preparation for the new charity season, warning lights

(March 2008)

During the 2007 charity season Charles (KF6TXI) purchased a Predator II warning light from Sound Off Signal ( and temporarily mounted this to his Honda Gold Wing GL1800.  The response using this light was astounding.  The light greatly increases the visibility and the warning to automobiles when escorting the bicycles.  In Charles’ words “this is the first time the cars did not play chicken with me on the motorcycle”.  As you know the Honda Gold Wing is not a small Motorcycle but the cars in California have a tendency to drive quickly (can you say Warp 9).  The Predator II warning light provided ample warning to the cars so they were able to give Charles, the motorcycle and the bicycles a wide berth.  Because of the visibility and the success of the Predator II, Ray (KD6FHN) and Billy (KF6WBV) purchased the same light. 

To understand why we installed these lights on Charles' Honda Gold Wing, Connie's Suzuki Bergman Scooter & Ray’s Gold Wing, we use these lights on our many charity events to help to protect the motorcyclists & bicycle riders. It is especially important in the areas where there is no bicycle lanes or even a shoulder on the road past the fog (right shoulder white line) line on some of the very narrow 2 lane residential streets.

These things are very, very bright LED lights (used on motorcycles by the local police departments) and they have a number of combinations of flashing sequences that you can change to the one you want or works best for your purpose. These lights are not cheap. But what is your life worth while working these charity events? If drivers can't see us now, they would have to be blind.

Just as an aside the Predator II purchased by Charles (Figure 1) and the lights purchased by Ray and Billy (Figure 2) are the same light but the cases have changed a little.  The newer light is a little slimmer and the mounting is slightly different.

In February / March 2008 the MARC family began preparation for the new charity season.  We began with the installation of a Ham Radio (Kenwood D700A), a GPS (Garmin GPSmap 276C) and a warning light bar (Sound Off Signal Predator II), for Connie’s (KF6YOM) Suzuki Bergman Scooter. 

The installation went so well that Ray (KD6FHN) decided to mount his Predator II light to Casper (2004 Honda Gold Wing GL1800).  What follows are some pictures of the finished installations.

Figure 8, Mounting for electrical switch. The switches are mounted in the fuel well. This allows the shelter to be removed for servicing without disconnecting the wires.  The forward switch (ON) is the Predator II, the rearward switch is for the fuel pump for the Aux Fuel tank.   The location of these switches allows the removal of the top shelter for service without disconnecting the wires.


Ray installed the Predator II to his 2004 Honda Goldwing.  Here are the instructions written by him for the installation


Figure 9:  This picture is to show you how I wired the Predator 2 and ran the wires down behind the passenger seat.


Figure 10:  This picture shows a close up of the white wire that changes the sequences of the pattern you want the Predator 2 to flash. There are many ways you can change the pattern by using a second switch directly to ground, but this is the very simplest way I can do it. You will see in other photos how I can pull that snap fitting apart and touch it to the trunk rack, which is grounded, and change the flashing pattern. No switches, no more extra wiring & etc. Doesn't get any simpler then that.


Figure 11:  This picture shows how I tuck that red snap fitting down behind the passenger seat and then when I want to change the pattern of the flashing, I pull the snap fitting apart and touch the male end to the rack and that shorts out the light and changes to flashing patterns.


Figure 12:  Here in the above picture the white wire is pulled out from behind the passenger seat with the female snap fitting still in place.


Figure 13:  In the above picture the female snap fitting has been removed and now all you have to do, with the Predator turned on, is to touch the trunk rack with the male end to change the pattern of the flashing. When you get the pattern you like best, put the female snap back on the male snap and stuff it down behind the passenger seat again. No fuss, no muse.


Figure 14:  In this picture you can see that the 2 long bolts are in place and the 2 shorter bolts have not yet been put installed. Because you can not get to those longer bolts once you level the bracket. Tighten the longer bolts up pretty tight, then start the shorter bolts, but do not tighten them, just snug them up a little so that you can still turn the bracket on the rack. See next picture for what to do next.


Figure 15:  In this picture above you can see that you can now take an allan wretch and tighten up the smaller bolts and level the bracket at the same time. You can also see how the longer bolts stick up through the bracket before installing the flat piece of strap aluminum that holds the Predator 2 in place.


Figure 16:  Once you have the antenna bracket level you can them put the piece of aluminum strap on the 2 long bolts. Those 2 holes are off set to the back of the strap aluminum so that the wider part faces to the rear of the motorcycle. You will notice that one of the holes in the aluminum strap is elongated so that you can square up the aluminum strap metal up to the bracket before tightening it down. Also the 2 bolts that will actually hold the Predator 2 down are in place but still up enough to let the bracket for the Predator 2 to slide under the heads of the bolts.


Figure 17:  Above: Here the Predator 2 is in place and the bolts that hold it in place are tightened down and the nuts on the bottom of the aluminum strap are tightened up to lock those bolts so they can not come loose. These pictures & instructions should just about do it for mounting the Predator 2. More help is available if needed.
