Hello all! I have a 2014 Honda Civic Si, and have ordered Philips H9 bulbs to upgrade my low beam lighting.
I was told on a Civic forum that I should also install relay harnesses, to keep things from melting. Basically that the factory harnesses were thin, and not up to the task.
What confuses me is that in the same forum, I also read of people upgrading to Nokya "stage 1" and "stage 2" bulbs; with only the higher level stating they need relay harnesses. My understanding is that "stage 1" are 65w, and "stage 2" are 80w.
I greatly appreciate everyone's input on this!
