Introduction: Squential Mustang Cougar Flasher
I loved the look of these sequential flashers on the early fords. My friend Marty had a Cougar with them and I really wanted them for my car. I took a look in the trunk to see what I needed to get. Since they were mechanical it made them easy to find. I then went off to the junk yard to get one of these setups for my car.
Step 1: Factory Cougar Flasher Modules
These are the factory motorized sequential flashers from a couple of early 70's Cougars. I remember getting these from a junk yard so I could add sequential lights to my Opel Manta. It worked pretty well. I got the second module to use as a spare but never needed it. To this day it still works fine.
Both of them had 4 cams. One only had 3 switches installed and the other had all 4 switches installed. I used the model with 4 switches so I could use the last switch to power the motor to make sure it always completes a cycle and starts over fresh next time you signal.
Step 2: A Good Candidate
My Opel wasn't the best candidate since it only had one signal and one brake light on each side. That meant another trip to the junk yard to get 4 more taillights. A little time with a sawsall and I had the needed 6 lights.
I got the Cougar relay module from the junk yard too but it was in pretty bad shape. I ended up using a couple of telephone style 4PDT relays.
My Monte Carlo was a much better choice but it had 4 lenses on each side. too hard to add a cam so one didn't get used.
A similar problem with my Fiero except by the time I got that car I had already made the first electronic version of the Cougar blinker. It was easy to add code and another Mosfet to handle the extra lamp.
My current conversion is on my 71 Mustang. It came from the factory with those triple lens lights that have the reverse light in the middle. It seemed like too much work to make new lenses that are all red so I took some sheet metal and made a new tail panel. I then added real Cougar taillights.
My next victim is my wife's Corsica......
Step 3: Building the Controller.
The first thing to do is replace the flasher with a heavy duty electronic type. I got that at the junk yard too...
Next you wire the inboard lights using the factory harness. The controller connects to this lamp and draws its power from that to light the next two or three lamps using a simple programmed delay. I like to coat the boards in liquid electrical tape .You need to make one module for each side.
These also work well on the front signal lights even if yours only have two bulbs. Just populate the board with only one lamp driver. I made individual boards with 1, 2 and 3 mosfets. I even made an 8 mosfet board to do a very annoying cylon effect on a traffic advisor stick.
