Couple weeks ago, in the middle of a freezing rain storm, I got pushed off the road by a tractor trailer. I was lucky there was plenty of shoulder and then an up coming exit ramp for me to make my get away. He obviously couldn't/didn't see me. Maybe because of the storm. maybe because my factory headlights are very fogged over. Maybe he was distracted by something else. I wasn't in the cab, so I don't know. I've ordered some new headlight housings, and will be installing them as soon as I get them. I will also be adding some true fog lights to the car to ensure I'm seen in foul weather, especially with all the fog we have been getting here in Central Texas (hill country). That should take care of the visuals. But I was laying on my horn, and he clearly couldn't hear me either. So I went looking to upgrade it too. I've installed the mini air horns on a few of my past vehicles, and was considering it, but I came across a set of twin horns that were supposed to be much louder than stock and looked to be "plug and play". So I ordered them.
