is this normal behavior for the blinker?
 

I copied this post from new members forum.

Good day all,

Im happy to say that as of July 2016, im an owner of a 2004 H2.

Something tells me I'm going to enjoy this forum, so without further ado, I have a question.

Are my side marker blinkers supposed to blink, while my headlights are off? Because mine don't, but if my park lights, and headlights are on, they do blink.

I ran into a fellow H2 owner in a parking lot, I asked him if could turn his rig on and activate his blinkers. His side marker blinkers worked both way (with and without headlights on). I forgot to ask him what year his H2 is.

Anyone?

surely someone who owns a 2004 H2 can answer this.

During the daytime with headlights off, do the led side marker lights blink when the turn signal is activated?

Much appreciated.

I have a 2005 and mine blink with lights off.

Interesting, I'm gonna have to look into it a little more.

I had a brake light go out, so I thought while I'm at it I'll change all the rear lights. After installing them all, is when I noticed the side marker not blinking w/headlights off.

Any suggestion, possibly the flasher relay?

I made a quick video to show what Im talking about.
