When your lights are sequencing too rapidly, causing the outer light to not fully illuminate, your original unit is most likely the culprit. This solid state unit replaces the small red (69-70) or green (71-73) flasher found under the dash, next to...

I had to buy these when I converted to plasma front and rear bulbs. Easy install, just had to find the originals, remove plug and a ground. I did have to swap positions of the wires in one of the plugs. Pay attention to and read the instructions because they tell you the proper wire placement.



I wish these had a round case like the factory flasher so they would fit in the holder better, but not that big of a deal since they are hidden on the backside of the dash.

I have reduced the ratings because a 5 star rating would mean the shape would be round like original cans to snap into the holders. Otherwise they work great.....A change to the installation is needed also. It was much easier to just unpin the wires from the plugs with a small eyeglass screwdriver and swap them to be the correct polarity vs. making the wiring adapters mentioned....i had to change mine on the emergency flasher can.

These work great - they stay on long enough for the lights to fully sequence. The instructions were very helpful. They alerted me to a potential factory wiring issue which I did indeed have, and gave clear instructions on how to overcome it.

Electronic Flasher

Ordered this for my 68 Shelby tail lights as I was not getting the outside LED's on the tail lights to flash on turn signals while still using the stock flasher. As it turns out, my issue wasn't the flasher at all. When I was doing all my testing, it was with the car turned off. Once the car was running and battery fully charged, my tail lights worked just fine with the stock flasher. I then swapped in the electronic flasher just to test, and with the engine running, it would not light the outside LED again. So, I put the stock flasher back in and am good to go...
