I did test it left to right, but the difference on the running lights was small. I'd like to test it with the brake lights with the thinking being that a percent increase of a brighter source would provide a larger, more detectable difference.

For example, a 10% increase on "10" would be 1, but a 10% increase on 100 would be 10---a output difference that could be more readily observed.
