How retentive is Mr SVA on the angle of the fog light?

If my fog light is 5-10 degrees off verticle will I get away with it?

i would like to know this to, i have the slim lcd ones a bit like the hellas and so its flat onto the rear panel and no real way of making it vertical.

sorry to say but i doubt it, it's the one light he checked carefully on mine

why does it have to be verticle, sureley it should be the angle of visability?

it says so in the SVA Manual, and it's to avoid dazzle. same rule for Normal cars

Why so strict? Not sure, but probably to do with preventing the direct beam shining into the eyes of the driver behind.

Will they check? Absolutely - he'll put a big set square up against it to check it is vertical.

I believe the reason he is so retentive on this is that it is a high intensity beam and you need the light pointing directly backwards to get the visitbility of it over distance as the warning to following traffic.

Also, as it is so bright if it is pointing into someones face behind you they cannot see where they are going and therefore not safe.

I used a thick piece of rubber on my foglight and shaped it and fitted it behind the light to ensure it was pointing as close to horizonal as I could. It isn't excatly there but is pretty close and he was happy with it.

Hope that helps in some way!

I Agree with the above - he will definitely check it, and it has to be spot on

It was a failure point on my test, it didn't point straight back due to the angle of my body

Well I can get almost vertical but not quite, also the lense in on the back of my wing in a cluster so it certainly wont point straight to the rear. I do however have a seperate lense which I could wire in for the SVA test and then remove afterwards, which is what I did for my last build. However, I would have the original lense in the cluster clearly visible. Would that be OK?

yes this is ok as I did just that and sailed through sva.

hth, john.

Depends on tester, mine said all rear lights to be vertical otherwise they were not"pointing to the rear" my fog was spot on the others were on the wings so sloped a bit. I made wedges by aluminium origami and he passed them at second test. BTW this was Bishopriggs SVA Centre
