Diy: Installing Resistor For Led Turn Signals On The Iq

[surfcitylocal]

If you want to rid your iQ of the "egg yoke" look of the stock amber turn signal bulbs you can replace them with LED bulbs. If you do that you'll have to deal with hyperflashing, the speed at which the LED blinks. The resistance on the LED bulbs is lower than that of the stock and your iQ will think you have a bulb burned out causing the turn signals to blink at double speed, the factory alert to replace a defective bulb. This is annoying to say the least but is an easy fix.

This DIY will explain how to install an external resistor to restore the regular turn signal blink speed and end hyperflashing.

The items you'll need:

2 6 ohm 50 watt resistors. Available on line or at your local electronics store

Wire

Connectors

Heat shrink tubing

Electrical tape

3M double stick tape

This is the 6 ohm 50 watt resistor

Strip your wires and solder one color wire to each end of the resistor. The resistor is not polarity conscious so it doesn't matter which wire goes to which post. Use the heat shrink tubing to protect the soldered connection.

Do the same to the other end post.

Your finished product:

Use 3M double stick tape to secure the resistor inside the engine compartment. I chose the edge lip of the front support.

Locate the turn signal wiring, peel off the electrical tape to expose the two leads.

Cut one of the leads at the point where you wish to splice in the resistor. Make sure you have enough wire to reach from the turn signal leads to the resistor.

Using a butt connector, splice the new wire with the existing wire coming from the harness. Splice the end going towards the turn signal bulb socket to the other stock lead.

At this point test your install to ensure that the turn signal is blinking at the proper speed. If your bulb is not blinking you may need to remove it from the socket and reverse it.

If everything works as it should you can use the electrical tape to cover the new splice. I used some small diameter wire loom as well to make the install look cleaner.

The finished installation...

This picture was taken before the remaining added wire was covered with the wire loom.

Now enjoy your turn signal blinking at the intended speed and the brightness of your LED turn signals.

No more "egg yokes".

Very professional.great pics. Evan i can follow that. Though dont have an IQ.

Hi Taz

Just for information, you can buy LED bulbs for indicator use that have a integral shunted regulator to offer the required load a incandescent bulb would offer. Nice tidy job anyway

Thanks David. I have been unable to locate said bulbs here in the U.S. and needed to get these working before I leave for Las Vegas on Saturday. A link to a site where I could purchase those bulbs would be greatly appreciated.
