Default Load resistors for LED turn signals

I bought my 01 F4i without any front turn signals. I've been looking at LED flush mounts and I know if you switch to an LED signal you need to use a resistor to bring down the power. Question is, how do I now which level Ohm and watts to buy for the resistor?

You dont need any resistors to switch from stock blinkers to LED ones

True, you don't "need" resistors when switching to LEDs. However, if you want the signals to flash at a normal rate you either need resistors or, what I recently did, replace the stock signal relay with an electronic LED flasher relay. With this in the circuit you can have up to 4 LED signals and the flash rate is still at the normal speed.

Here's where I bought mine. Scroll down to the bottom of the page for the motorcycle applications. The LF1-S-FLAT model plugged right into my OEM wire harness connector.

The LED flasher relay is a much better way to go. Most of them will allow you to have a combination of bulb and LED signals, and you don't have to monkey with wiring in resistors (which can be harder than it sounds).

Here's another source of relay: http://www.customled.com/products/fl...sher_relay.htm They even have a fancy, more expensive one that allows you to choose from 10 different fancy flash patterns.

As others said... Go with the relay! 1 relay is way better than adding/removing resistors per light.

Thanks RoadiJeff and Aken for the info

@RoadiJeff - I just purchased that flasher relay since I am buying LEDs for the front and rear signals, so I should be set now.

Thumbs up

Thanks dude

edit: I can just leave the wire hanging and not even worry about having it be a running light at all right?

I have front (air ducts) and rear (pegs) LED turn signals and flushmounts with regular bulbs. One day i tried to install a LED flasher relay and the flash rate didn't change...
