HT5, that would probably work. Can you do one more photoshop? I'm looking at my 89+ tails now and there is barely enough room for one row of LED's above and below where the 3 amber bars are, and that limit extends across the housing. I think if you could trim off one complete row of the LED's off the top and bottom of your image (all the way across), it would be much more accurate.
Also, there is not enough room at the ends to have a complete vertical row of red LED's beside the amber bars to give the overall light bar the closed look. Some of the LED's would shine through the clear sections of the lens, which might not be too bad, but would probably look brighter than the rest.
