When driving at night in your '99-'02 Dodge Ram truck, have you noticed the increased lighting brightness when you pull back the switch to go from low beams to high beams? In the transition you activate a momentary switch position that illuminates both the high and low headlight beams. Likely you've driven and tried to keep the switch in the momentary position, but the left hand tires quickly and the headlight switch is not designed for a continuous amperage draw.

No doubt it would be nice to enjoy the vision benefits of the combination high and low beam patterns. The answer: Brite Box! The Brite Box module plugs right into your Dodge Ram's existing wiring harness and allows simultaneous operation of the high and low beam headlights along with the fog lights without placing any additional loads on the vehicle's stock headlight switches or wiring.

  • Unplug the harness from the light (passenger side light is easiest to access) and plug it into the Brite Box.
  • Take the pigtail plug from Brite Box and plug into the light.
  • Connect the Brite Box positive wire to the battery positive.
  • Secure the Brite Box to the truck's under-hood.
The Brite Box M4B unit works both headlights.

NOTE: Must be used with stock wattage bulbs.

NOTE: This Brite Box will not work on trucks equipped with day time running lights.

NOTE: Due to Canadian motor vehicle regulations, this product is not available to Canadian customers.
