i have a 06 f150 Xl all manuel, so i have no fogs. With the high beams on, pushed forward, there not as bright as holding it on. Is there a way to swap the light intentisy?

 

When you hold your on your high beams you've actually have both the low and high beam on at the same time. That's why it's brighter.

I don't know enough about the wiring to say whether or not you could swap the settings, my guess would be yes though.

is there a product called a "bright box" it let both the highs and lows on at the same time?

 

actually, you can do this very easily yourself. all you have to do is add a diode into your headlamp wiring. if you add a diode in between your high beam and low beam wire, you will allow the low beam to stay on while the high beam is energized. if you install it with the band side of the diode on the low beam wire, you will be good to go..... just solder it in and your all set. and, you only need to do it on one side, and both will work off of it.

the only other thing that a "bright box" or aftermarket harness would offer is a higher voltage by means of using a relay.

 

Brite Box works great - lets you have high, low and fogs on at the same time. About $100 and very easy install.

 

Also kills the average life of your bulbs twice as fast. Having both filaments lit, you risk melting something.

For $15 more, you can get a lower wattage HID kit witch is twice as bright.
