got foglights working, anyone know a sure-fire way of aiming them?

besides doing it at night :/

i know there's an optimum angle, but i'm not sure how to go about achieving this.

 

well mine i adjusted straight in line with my parking lights..

they just had a screw up on top that goes in and out changing the angle of the foglight. basically just pointing them straight ahead..

 

Foglights, you want to have a 1 inch drop every 25 feet. Driving lights will be farther out (like 35 feet IIRC). That's a pretty broad generalization. Your lights should have come with aiming instructions, those are the best to follow.

 

well these are the stock foglights for an 87 IROC

so there were like, no instructions on how to position them correctly (I know you adjust the screw) but just don't know how to go about adjusting them to the optimal angle

also, when it says LEFT or RIGHT.. on the foglights does that mean looking towards them, or from the driver seat?

not sure if i have them correct, or not (as one side of the foglight seems to stickout further than the other side)

 

Fogs you generally want straight ahead, but if you are going to have any lateral "cant" at all, then you want it biased towards the "right" which means passenger side. You're supposed to orient as if you're sitting in the driver's seat. If we oriented as if looking at the front of the car, then we'd all be driving on the "left" side of the road.

The reason for biasing towards the passenger side is to help light up roadsigns, pedestrians, animals about to leap onto the road, and to prevent dazzeling/blinding of oncoming traffic.

Look at the beam pattern not the light itself. After all, that's what lights up the road.
