Fog lamps

LH side fog lamp was out. Found both the socket, reflector and bulb were bad, housing was slightly rusted. Replaced entire unit. This pleased the state safety inspection people. But, I don't understand exactly what direction these lamps are supposed to point. Right now, they are pointed outwards right on the RH and left on LH, and up toward the trees on both of them. Noted the inspection people did not do a directional check on the headlights either.

Am assuming the fog lamps should point directly forward, and slightly downwards???

I agree with Dafey, point them where you want, especially of the inspectors don't seem to mind if you're using them to hunt owls.

Fog lights are meant to shine low and illuminate the lines in the road. They should ONLY be used with your low beams (not your parking lights or high beams), if they point up, it's like driving with high beams on. Any driver's ed student knows that high beams reduce visibility in fog. Remember in fog your head lights help other cars see you, your fog lights help you see the road.

Fog lights are supposed to illuminate the road surface during foggy weather, they do that by being aimed low and projecting a wide flat beam of light under the fog, and another reason they are usually mounted under the bumper, close to the road, otherwise the suspended water droplets that make up fog scatter the light and reflect it back at your eyes. Thats the reason low beams not high beams are recommended. Fog lights aimed to high produce a lot of glare when they are used as drivng lights(which too many people seem to think they are, or they just think its kool to drive with them)

Upon further reflection (no pun indended) I realized the inspector and the local constable may have different ideas about the correct aim. Mine are almost as the OP suggested, just below horizontal and a tad wide. I only use them when I'm not facing opposing traffic so as not to interfere with the other driver's vision.

We rarely have to deal with fog here in the desert, but dust is sometimes an issue. The same principle applies to both. The fog lights need to be low shining on the road surface so you can see it when their are very high particulate sin the air. Shining up the lght just reflects off the fog/dust and blinds you.

Had just that happen the other day when coming back from an evening tournament when fishing with a buddy. The wind started kicking up a blinding amount of dust on the road home, and I had to remind him to switch to his low beams so he could see.

Thanks. This I will correct. I live in rural area. There is no illumination of the road from overhead lighting, pitch black. Any illumination pointed at oncoming traffic blinds the driver of the road ahead. There are vehicles whose fog lamps are pointed a bit too high, and blind oncoming traffic which includes myself.

My uncle (now deceased) used to run a Texaco station with a garage. My dad and I used to visit him there. There was a conversation I remembered regarding front end alignment, and headlight alignment. Seems the driver and passengers are a factor in this, especially front end alignment. Typically, there's no one in the vehicle when such alignments are taking place. Is this true?
