I'm not promoting this brand: https://support.kchilites.com/hc/en-...ight-patterns-
-just using the link to show the difference between fog, spot, flood and driving lights.
Fog & driving lights would be street legal.
I put a mix of cheap off road flood & spot lights on my motorhome. I haven't used them while driving yet because it is rare for me to drive at night. They're not meant for street use. My plan is to use the flood lights when turning onto secondary road or when entering dark exits etc. The flood lights cast a really wide beam in all directions so would illuminate tree branches etc.
The spot lights I added were probably not needed. High beam does a good enough job on the road when needed. Maybe they'll come in useful on some moonless night with no oncoming traffic.
Flood lights wouldn't be good in fog as they'd light up all of the line of sight particles in the air.
I have tested my new lights at night while parked and really do like the wide flood light beam.
The ideal combo for me would be street legal fog lights to illuminate a wide area of the road in front of the coach and flood lights for those occasions on dark secondary roads or campground entrances to see well off to the sides and overhead tree branches etc.
I ended up with 3 pairs of lights (4 flood/2spot) on three switches for versatility, appearance and redundancy in case some fail.
You should be able to look up the Rough Country part number to confirm that it is a fog light pattern. If it is then that should be a nice add-on to your coach.
Hopefully this also bumps your post up and someone with a Bay Star will offer some advice.
