I was able to find the exact replacement amber (1A-S-20A) and red (1A-S-20R) lenses. I did a Google search on kaper2 (or Kaper II), and found replacement lenses.

Their replacement lenses are shown as measuring 4 inches long, by 2 inches wide by 3/4 inches high. I pulled one of the Optronics # A32RB off of the shelf, and measured it using a dial caliper. I came up with 4.013 inches long, by 1.97 inches wide by .67 inches high. I suspect that in measuring their lens, Kaper II might very well have rounded the decimal to the closest relevant fraction. If this is the case, the # A32RB for red and # A32AB for amber would work for you, since the measurements are so darn close.

Because we cannot be absolutely sure about their measurements, I would recommend replacing the lights altogether. The lamps themselves only cost 50 cents more than the replacement lens.

If you wanted to go that route, the amber lamp is part # MC32AB and the red is part # MC32RB.
