I found an article about it: https://www.macsmotorcitygarage.com/a-cool-idea-at-the-time-the-hurst-lightning-rods-shifter

Hurst Lightning Rods, an aftermarket performance shifter marketed in the 1980s

The Lightning Rods system was set up to work like any ordinary automatic gear selector, more or less, with a conventional PRND shift pattern (as shown in the top photo). The difference was in the two additional levers: the far right lever and release button performed the 1-2 upshift, while the middle lever and button performed the 2-3 upshift. Or the driver could simply leave the lever in D for Drive or OD for Overdrive and drive normally. In that regard, the Lightning Rods setup was not unlike the Hurst Dual Gate aka “His ‘n Her” shifters of previous years.

I have to say that I'm having issues understanding what this means in practice. :D
