Diode Dynamics LED Turn Signal Flasher for all 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 and 2004 Mustangs with LED Turn Signal Bulbs.

If you’ve recently installed LED bulbs in your turn signals, you may notice that you have the common problem of ‘hyperblinking’. Hyperblinking is when the ECU in your Mustang thinks your turn signal is burned out due to the reduced resistance the LED bulbs put out in comparison to your OE incandescent bulbs. The ECU’s reaction to this is to increase the speed of the blinker so the driver knows that one of the bulbs is burned out, and it can get annoying very quick.

That’s where this Diode Dynamics LED Turn Signal Flasher Module (DD4005) comes in to fix the issue which will eliminate the hyperblinking that aftermarket LED bulbs create on your 1994-2004 Mustang.

To slow down the blinking to regular speed, you can splice in resistors to increase the circuit's power consumption again. However, that requires permanent modification to your factory wiring harness. Whenever possible, replacing the flasher with a module like this is the easiest option. This is the unit that actually controls the blinking speed, and makes the "clicking" noise.

This LED Turn Signal Flasher is 100% plug and play on your SN95 or New Edge Mustang. All you need to do is remove the factory flasher and plug this one in. Simple as that!

Order a Diode Dynamics DD4005 LED Turn Signal Flasher for your 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 or 2004 Mustang with LED Turn Signal Bulbs from CJ Pony Parts today!
