nothing you can do. requires replacing the wires from the fuse box by thicker wires, which is not a layman-type job.

the variances are statistical in nature, so a physical solution, like caps, wont help. by choosing the low end of the range of forward voltages you've immunized yourself from these variances, tho, so no worries.

as for ''clever tricks that do not require too much extra circuitry" there's constant current sources, like in the pic for $8. this one uses a DC input but many others work directly from 120Vac. it's possible to make your own current source using a voltage regulator like an LM317; while these are simple to make, they're inefficient so they'll get very hot.
