Timely post. I lost one of my front corner clearance light lens on the last trip
I'm think now would be the time to put in some LED marker lights if the price has dropped to something reasonable.
Also, I was wondering about the ability (and legality) of having flashing clearance markers for certain situations. I was thinking about this while driving over the mountains this weekend and then a little later I saw a semi hauling a big piece of earth moving equipment that had exactly that. It had high mount yellow LED clearance lights that flashed like an emergency vehicle. He was traveling at about the same speed that I fall back to on the big grades.
Ooo, thanks for the link Terry. I'll report back on what I end up with.
