All Your Light, When You Need It
Ever notice how your fog lights cut out the moment your high beams come on? With auto high beams that hand-off can be downright distracting — and off-road, you want every lumen your truck can throw.
Bambi Mode keeps your factory fog light circuit lit right alongside your high beams. More light down low, more light far out, no flicker between the two.

Program in Seconds — Then Unplug
Installation could not be easier: plug the programmer into the diagnostic (OBD-II) port below the steering wheel, let it program, and unplug. No tools, no wiring, no coding knowledge.
Want stock behavior back before a trade-in? Plug it in and revert — as many times as you like.
