Third tail light conversion of the third kind

[bradleyheathhays]

'96 XJ here and although I've got a 3rd tail light it only lights up when the brake is applied.

Is there a way to bring that center light up to modern standards and rig it to stay on all the time (when the lights are on) and get bright when the pedal is pushed?

What do you mean to stay on at all times?
