Freebeard, It never ceases to amaze me. Something seemingly straight forward and simple, can have a lot of specific details enabling it to work properly. That's one of the reasons vehicles are so fascinating to me.
I understand the idea of needing a sharp cut off on the top of the beam, but I don't understand needing the fog lights mounted higher.
My understanding is totally based on my own observations and speculations: but wouldn't it be good to have the fog lights really low so they can connect with something solid easier? Then having to try to cut through a large amount of fog? Factory fog lights are the lowest lights on a vehicle and often placed as low as the bumper and inset bumper mounting will allow.
The fog lights themselves were something my dad bought for our Jeeps, but never got around to using them. We no longer have the Jeeps, so he let me use them if I wanted. I love the blue housing color, as it matches nicely with RAVadoodle, and they are narrow for less aerodynamic drag, but I'm not set on keeping them if they don't serve my needs.
I've got some time before the fog starts to become a problem. I will look into this subject until I have a good understanding and can having something that WILL work.
Thank you for sharing your knowledge about this.
Edit: Oh, and I have yet to actually try the fog lights at night while driving. I've used them to help see while picking up tools after dark, but that's about it. Maybe I'll take RAVadoodle for a spin tonight, just to try the lights out. I may be totally disappointed, and need to get something else. And everything else seems to be bigger, which means I will HAVE to mount them in the lower grille.
