Changed all the lights on my Girlfriend's Mini Cooper last weekend, since then the indicators have been going crazy (assuming due to power consumption being very low).

I know you can replace the relay for the lights so that it works with LED properly. Do you know what I need to do in order to fix this? I've found these plugs but unsure if I need to replace something that's there or add into a blank slot - http://www.autobulbsdirect.co.uk/LED-Flasher-Unit.html?gclid=CPiKweC03MoCFckaGwodt-8Pow

Below is the fuse box and fuse box diagram for reference:

The reason for this is LEDs don't draw as much power as regular incandescent lights do. By putting the LEDs into the vehicle, you are making the vehicle believe the lights are out because of the lower draw. The indicators blink faster to indicate to you, the driver, there is a bulb out which needs to be changed.

One way to fix this is to put a resistor in between the two wires which deliver power to the LED bulb. The resistor will allow for a little more current to pass through back to the blinker relay without causing a short and blowing a fuse. You'll need to look up exactly what you'll need for your application. You might want to start with the manufacturer and ask them what size of resistor is needed.

The relays you have shown in the link are the typical relay plug pattern. If these are the correct pattern for the Cooper (I haven't found the exact one yet), then you can use it without putting a resistor into the wiring at the bulb end. As long as this fits, it's all you'd need to make it work.

I know this is an old question, but in the off chance someone else is looking for the answer, new Mini Coopers do not have a flasher relay. The flashers are controlled by the BCM. You will need to wire in the resistor to cure the fast flash issue.
