Light your path
Properly aiming your headlamps can improve night vision and reduce the risk of blinding oncoming drivers. When a fix is needed, a dealer charges about a half-hour of labor to use a headlight focusing machine. While that’s not unreasonable, on some trucks you can do it yourself by simply turning screws.
Sometimes a misdirected beam is caused by an imbalance on the truck. Before working on the lights, take these steps to assure that the truck body is as level as it should be, then check to see if the beams are still off:
• Fill tires to correct pressure.
• Ensure air suspension is operating and at optimum spec for ride height.
• Fill the fuel tank.
• Have someone in the driver’s seat.
• Ensure that hood bushings are not too worn. Wear is indicated by flexing up and down or rocking when opening or closing the hood.
• Ensure the hood is adjusted for proper alignment on both sides. Bolts can be loosened and the position of the hood on the brackets adjusted, if necessary.
• Ensure that the rubber pads on the cowl and corresponding cups in the hood are in good condition.
