I wanted to share this information for anyone thinking of converting to a Sequential turn signal system. This was a quick design I drawn from components on ebay. Accessible at a minimum cost (ebay $6 for 2ea) and not complicated to wire.

This is not a post to sell anything, Please do not PM.

Hope this will Help, This is for a 3-segment tail light Sequential Turn Signal system (Ford, Shelby, GM, Chrysler, etc....) you will need two of the adjustable Timing Circuit on each side wired to each left and right light. The Manufacture Flashing relay needs to be replace with the adjustable Flasher Relay Unit mentioned in Post# 12 and adjust 0.80-1Sec

This is the simplest way to perform the Sequential and can be used for a LED or Incandescent Bulbs.

This circuit like others on the market when you step on the Brakes, the 3 Step Sequence will happen on both side then stop on the side light is constant (Brake) but will continue on the turn Sequential signal side.

Actually to prevent the 3 Step Sequence event when the brakes are applied a 555 timing circuit can be use to recognize the side not to Sequence. This will mean separate wires to the two delay relays output. As mention in Post # 12 This circuit is already built in the LED strip on the market and can to removed and place in this circuit. But that design is only for LED not incandescent light bulb. The built in relays (in Blue) is design for 10A*
Actually this is the modern design of the 1964-6 Thunderbird Mechanical, Cougar and Shelby's IC system.

This can be modify to 4+ lights by just adding additional Delay Relay Circuits and adjust timing to collectively 1sec. or the timing you want. Remember the Flash Relay unit also has to be adjusted.

Sorry had to PhotoShop the drawing together. In my younger years I could of drawn this in ACAD in about 15mins Now, Well let's just say my imagination is still there but remembering what I'm doing gets a little cloudy.

There are other design but will be more complicated.

Other Systems Cost $100+

About 15 years ago I used <gofasrforless.com> Schematic for my sequential build.
The inexpensive delay modules were not available at the time, I have seen them on Banggod.com for a few bucks each.
View attachment 781332
The schematic is partly correct but the main first light is not shown.

I have attached the modify Schematic.

The timing is off.

I'll try to adjust the John DeRosa (Hotwaterwizard) Schematic.

I didn't know this has already been built. A friend email this youtube video.


The Mini-Relay solenoid in the these Circuit Boards are much smaller and less noisier compare to the standard Auto Relays.

But using this devices you don't have to be a electrician to built. The other circuits, You will need to know how to built/solder (and order) each Electronic components and maybe a bread-board.

It is the ability of each individual knowledge, cost and time they are willing to spend to create the Sequential Turn Signal system

The LED's normally used on most Mustang After Market Systems are outdated using DIP- LED's .(But easier to Solder/Assemble.) They also can be order in Different sizes.

The SMD's depends on the IC itself (3528 vs 5050 vs ...etc) is Brighter than the DIP-LED's

The newer COB is more advance and illumination is much Brighter then either the DIP-LED and SMD.

The biggest difference is some of the DIP/SMD IC have different Color changing within it's circuit.
Example: Both the 3528 and 5050 is capable of creating millions of color variations on each IC.

Here is a link which a Member gtonavy posted of his Sequential Tail Light Project.


Sorry for the technical lesson, I just thought it was important to mention Pro and Con .

One last thing, if you look closely in the strips you will see a "Scissor" or a opening which normally every three IC. Since each IC is about 3.1V-3.6V DC they can be cut into small strips then re-wired (2wires each strip Poss & Neg) to create the size to go into a Lens, well I'll leave it at that.
