Especially if the LED is packaged up for a specific application, for example to replace an existing incandescent bulb. You need to have information for the specific part you're using to avoid a mishap.

You can also buy a $15 blinker relay specifically for leds. I got mine at cycle gear and also online. PLugs right into the harness where the old one was and you don't need to mess with anything.
We're not out here to rough it. We're here to smooth it. Things are rough enough in town.
