You could always buy your LEDs on AMAZON, but you will not get the expert selection of a truck headlighting specialist there.
As for cost: Divide the price by the expected lifetime in months, and you will see that we are cheaper in the long term.
Note: FX-AA complies with DOT guidelines. We restrict high illumination LED bulbs to projector-lens headlight applications, which are designed to reduce glare. Our reflective headlighting product choices sufficiently illuminate but are less potent than projector selections to minimize glaring.
