The datasheets I've looked at for LEDs all seem to have very linear light/current curves, but maybe yours are different.
I've just gone off on a bit of a thought tangent: as well as red LEDs, you could incorporate a similar array of 935nm infra-red ones and drive them with a noisy PWM switch centred around 1kHz: just to make things a bit more difficult for those laser wielding traffic police. :lol
