With some luck you can hopefully figure out how to rewire and get run power and brake power to the correct places without having to exchange the whole assembly.

If the circuit is designed to output low brightness @ reduced voltage and full brightness at 12v, you should be able to wire the top lamp in parallel with the bottom lamp and get four run and four brake lights like I have.

You will have to disconnect the top run light ckt which runs at full voltage expecting a low watt filament
