Wig-wags on a motorcycle? Who would want those!? Well, I imagine quite a few people actually would. I wanted them to go along with my blue EMT lights that I run on top of my fairing, but I could see lots of patriot guard members wanting them for missions, parades, and such. So, let’s go through the process!
(Skip to the bottom if you’re just looking for the video of them in action)
First thing first, to setup a light bar to wig-wag, you need a light bar. I’ve gotten a few items from Joe @ http://www.chucksterscustoms.com/ and he had a real nice light bar setup for the Nomad. I was a little worried about them fitting since they are made for Nomads with the stock windshield, but talking with Joe, he said if they didn’t fit, send them back and he would give me a refund. I got the lights in, and sure enough, they didn’t quite fit. The arms were a little to short, causing the spots to aim downward. But I loved the looks of the spots and bracket, so I emailed Joe to see what the options were. He told me to draw up any changes that needed to be made, send the old ones back, and for an extremely reasonable cost, he would make new brackets for me! And to top it off, the turn around was quick too! But while I wait on the new brackets, I might as well get the wig-wag unit all wired up! I’m going to be using a Whelen UHF2150A Wig-Wag unit for this. Cost me just over $60 after shipping. I made a wiring schematic to help me keep things straight when I started soldering. Normally, the unit has the low beams on all the time, then to wig-wag, it flashes the high-beam. Since we want the bulbs to flash on and off, I had to make a few changes to the wiring diagram that came with the unit. We’ll see what the life of the bulbs is when they are blinking on and off all the time, but it really shouldn’t get used too much. When the first relay is activated by the key, it puts power to the WHT/BLU & WHT/YEL lines which are straight through to the lights, so the lights come on. When the second relay is activated by the EMT light switch, it kills power to the lights and activates the Wig-Wag unit which will then provide power to the lights in the desired pattern. Now that the planning is done, it’s time to start wiring. Here is the unit bolted to the right side fairing bracket. It’s back against the inner fairing, so clearance will not be an issue. The two relays just attach to the lower bolt of the Whelen. The left relay will turn the spots on when the key comes on. The right relay will take spot power off of constant and onto the Whelen unit when the main EMT light switch is flipped. Here is everything wired up. The coiled WHT/VIO wire is the wire that you apply a momentary +12V DC to in order to change the flash pattern. I’ll cut and cap this wire after I get everything put together and I choose the flash pattern I want. The blue and the yellow wires will go to the + wire of the spots. The bracket’s weren’t in when I took this picture, so I had the lights sitting on a box so I could test everything. Now I had the wig-wag unit all wired up, but I still had one more day until my brackets were supposed to show up, so I decided that I would add 4-way flashers and then set them to come on with my EMT lights, but also add a second switch so I could turn them on by themselves. I happened to have a flasher unit, so I decided the easiest way would be to run a wire from the front of the bike to the flasher unit under the seat and tap into the turn signals there. Here is the flasher unit wired up. There is just enough room to the right of the battery to hide it down in there.
After this point, the brackets came in!! Great work by Joe once again! Now that I had the lights on the brackets, I could put the outer fairing back on and test out the whole system! Here’s a video I took showing off all the lights at night in my garage.
