The '05-'09 Mustang LED Sequential...
The '05-'09 Mustang LED Sequential Taillight Kit from Mustang Project plugs into your Mustang's taillight sockets in a matter of minutes. Connectors crimp onto the taillight harness without cutting. Both sides are identical; one side is shown here.
LED technology is changing the way we see the light. In its commercial infancy in the 1970s, the light emitting diode (LED) was used primarily as an indicator light in electronic devices. In those days, we didn't understand the light that came from such a tiny little diode and wondered why they lasted virtually forever. As the technology has advanced, manufacture of the LED, not to mention its use, has become more economical, making its technology even more widespread. What's more, LEDs have gotten larger and even brighter to make them more appealing. Never has this been more apparent than in automobiles and large billboard screens along the Vegas strip.
Mustang Project has pioneered LED technology in Mustangs of all vintages. Sequential LED taillights for '05-'09 Mustangs are what we're talking about here. Mustang Project's S197 Mustang LED Sequential Taillight Kit transforms already exciting three-element taillights to attention getting magenta photons. Two types of systems are available-sequencing 1-2-3 and chase mode. They also sequence when you step on the brakes. Suggested retail price is $318.99 plus shipping. Installation is easy and can be performed in about one hour.

Then remove the trunk tail panel. |  |  With an 11mm deep-well socket,...  With an 11mm deep-well socket, remove the taillight module fasteners, three on each side. Then slide out the taillight modules from the rear of the car. |
 This is what you can expect...  This is what you can expect to see with the module out. Take note of the sockets and number of wires to each socket. There is an inner, middle, and outer socket. The inner socket is the only one with a blue wire, which makes it easy to identify. The middle and outer sockets are both fitted with the same red and white color code wiring. However, the middle socket has four wires and the outer three. Both sides are mirror images of each another. |  |  If you trust your memory,...  If you trust your memory, remove all sockets as shown. Otherwise, do one socket at a time, removing each bulb and installing each LED module. Use a small screwdriver to gently remove each bulb if any happen to be stubborn. |
