I'm struggling with rear light location on my Fury to comply with IVA. It seams that IVA regs are open to interpretation and I'd apprecaite feedback on your interpretation and any experience on how IVA examiners check compliance.

Note, I'm using Hella LED lights, the ones with an outer ring and mix/match inner and planning to use two pairs - i.e. two lights on each side of the car. A layout I've seen on a few Fury's and 7's.

The regs say the maximum distance from the side is 400mm, but I'm struggling to get both lights within this - measuring from the widest part of the car (rear wheel arch) and the edge of the light. So my questions about interpretation are:

Do both lights need to be within the 400mm limit?

Is the measurement taken from the widest part of the car or edge of the rear panel?

Is the measurement to the centre line of the light or the edge?



Many thanks.

The 400mm is measured from the widest part of the car. So thats the rear wheelarch edge (for front and rear lights).
It's measured to the outer edge of the lamp. Max seperation is inner edge. max height to top edge and min to bottom.
It applies to any lamp cluster as far as I know. What combination of lamps are you using?

Both need to be within the 400mm measured from the widest part of the car, and I am pretty sure the 400 mm is measured to the edge of the reflector.

I think 2 light clusters close together are considered as one, there is some guidance in the IVA manual that shows a diagram with reflector.
Many fury's have passed IVA with multiple rear lights so as long as the outer is within the outer distance requirements and the inner within the inner requirements and both within the height range I can't see a problem.
