Just find yourself a rocker switch Bran, w/amber indicator of course! Add it to the thin face-plate just in front of your shifter tap this into one of your car's accessory circuit. Problem solved. Could add a few more next to it also... Rocket Launcher, Xray See-through Vision, call Lily over secured line, Jettison Oil, etc etc
Sure you could find the equivalent locally:
e.g.
12VDC ON-OFF LED LIGHTED ROCKER, AMBER | All Electronics Corp.
