Or how about a long run of thin wire to the brake light.

It starts off with an OK gauge of white going from the battery and fuse to the ignition switch. Then it changes to thinner wire going out to the left switches where it's not switched but simply connects to a different color to return to the center then back to the other fuse then forward again to the two brake switches then back to the light fixture.

There must be over 15 ft of thin wire for the brake light -- a guarantee of voltage drop even at just 2.5 amps.

When I was setting up a redundant LED brake/tail light, I was amazed at the low voltage on the brake circuit compared to the reasonable voltage on the taillight. I had cleaned and greased all the electrical connectors about 2 months before adding the LEDs. Remove the incandescent bulb and the voltage improves because the voltage drop in wire is proportional to the amperage.
