Aren't those the 6 required to activate the Stargate?
;o)
As for a serious answer, I don't know, sorry.

I don't believe that's the right place to be posting source.
Anyway, the code that seems to be causing the problem is in this bit:-
#declare Chlitglass2=pigment{ gradient y color_map{[0 Red*2 filter
.9][11/18 Red*2 filter .9][14/18 Yellow*2 filter .9][18/18 Yellow*2
filter .9]} scale 18}
If you remove the "*2"s then it renders correctly.
I don't understand the details of why you see the effect you do.

neither do i.
i tried your suggestion, it's an improvement but I can still see a
difference betwwn the chevrons. i'm trying to make them all the same
but can't find out why they differ.
does anyone else have any suggestions?

Do the chevrons have a high ambient value in their finish? They should if
you want them to glow. The 3 un-lit ones might just be shadowed by
something.

The only remaining differences seem lighting effects due to the fact
that the lights are striking Chevron6 at different angles. One way to
get rid of such lighting effects would be to remove the filter component
from Chevron7 (so that you can't see the specular reflections from
Chevron6 behind it) and possibly give it finish {ambient 1}.

Thanks Mike!!
finish {specular 0.7} in SGTex was screwing it up.
i fixed this by making a thin section of Chevron7 with white pigment.
so that Chevron6 would not show through.
that way I could keep Chevron6 as is.
rendering the sucker again but will put the rest of the gate in the picture.
Will post it later today
#declare LitChevron=union{
object{Chevron5}
object{Chevron6}
intersection {object{Chevron7} object{Chevron7 translate <0,.002,-.002>}
no_shadow pigment{Chlitglass2}}
difference{object{Chevron7} object{Chevron7 translate
<0,.002,-.002>} pigment{White}}
cylinder{y*109,y*112,.15 scale<3,1,1> translate -2.2*z texture{SGTex} }
object{chevlightshp pigment{Chlitglass1} finish {F_Glass1} interior{I_Glass}
translate y*106 translate z*-2}
object{Chevlights translate y*106 translate z*-2}
}
