    I replaced my burned out front sidemarker lights the other day and noticed that they are steady on, along with the parking/turn signals. I am pretty sure that the sidemarkers are supposed to be off, but alternate with the parking/turn signals. Does anybody know if this is a wiring issue from Blizzard? Anybody else's GM truck do this too?

    Sorry, its on a 3 or 4 year old 810 - so PH1 I believe. It happens with and without the light tower connected, and is the same on both sides.
