I don't think they are.
Now that you mention that(...the 3 wire set-up) it's starting to come back to me that they were running light(s) as well.pretty sure they were, thats why it has a three wire setup.
Yea..what he ^ said...theyre running lights.yep they are running lights also..
Previous owner of mine had hotbody lights(two wire) got rid of those and went with watsens so i could have my running light feature back(plus they look better).
