Autotrix Modified Flasher - compatible with 1996-2004 Mustang

I have a 2004 Mustang that I purchased last year. Upon replacing a burned out taillight bulb, I noticed the factory wiring harness was replaced with an aftermarket one that is support to allow for the sequential flashing of the rear turn signal lamps. Since they were not "sequencing" I assumed it did not have the necessary modified flasher. I ordered it from Amazon and when I went to install it, there was a modified flasher already in place. I figured it was faulty and installed the Amazon one. Same result. If you squint it kind of sequential flashes. Not sure if the harness is bad, or that is the best it can be.

I love!!!!I ALREADY had the relay for my lights and they were so fast.I wanted to slow it down and the modified flasher was a great choice.I have had it since February 13th and it still makes me happy.If you want to slow down the time for your blinkers, I totally recommend.

If you have a mustang this is a must, PERIOD!!Mine stopped working in about 2 rides. Can’t exchange it, need to be refunded. Bummer!

These worked great with my sequential taillights on my 2000 Mustang! It helped make the sequential animation more pronounced, and installed in ten minutes.

Works as intended and designed... I purchased a sequential turn signal harness for my mustang and this makes my light operate as intended.

Super simple install. To remove the old one, pull it down and back, kind of toward the gas pedal, only parallel to the bracket it's attached to. Took me 5 minutes to install. Sequencing could be slower still, but this looks much better than stock flasher.

Works good and still working ,I like the speed of the sequential flash.
