Can you or do you have any pictures of the LP4’s mounted where you are saying the wiper arm hits it?
I know the LP4’s are quite a bit larger than my setup.(Squadrons) LP4’s are only 3.2” deep VS the most common light (XL80’s) that are 3.650” deep. LP4’s are wider and taller.
Yeah, its really hard to get a good shot - and the wiper arm doesn't hit on the driver side now that I moved it outward. For reference - the driver light I'm using the center hole to mount the light to the outer slot of the SDHQ bracket. For the passenger side, I had to use the inner slot of the SDHQ bracket and the far slot on the BD bracket to bring the light as inboard is possible.
You can see how close the light is to the antenna - there is no other position to where you can mount the light.
Here you can see how it is mounted from the light bracket to the SDHQ mount, again all the way inboard. Don't mind the janky tape
So now on the driver side, you see it is not quite all the way outward, I could go one more slot over but I don't need to, the wiper arm does not hit the light here. It is super close, but it doesn't hit.
Here is the mark on the wiper arm on the driver side from hitting the BD mount bracket:
and finally, here is a shot of the truck - one may not notice that the lights are not even side to side, but they are not even side to side and it's annoying AF.
