Lights

Poor lighting can result in reduced visibility when driving. Headlight and taillight lenses become dirty during normal operation. Clean lights frequently and replace burned out lamps promptly. Do not operate this vehicle at night or in low light conditions until the headlight is replaced. Always make sure lights are adjusted properly for best visibility.
When servicing a halogen lamp, don't touch the lamp with bare fingers. Oil from your skin leaves a residue, causing a hot spot that will shorten the life of the lamp.

Headlight Beam Adjustment

Image
To adjust the headlight beam, do the following:
  1. Place the vehicle on a level surface with the headlight approximately 7.6 m ( 25 ft) from a wall.
  2. Measure the distance from the floor to the center of the headlight and make a mark on the wall at the same height.
  3. Apply the brakes. Start the engine. Turn on the headlights.
  4. Observe the headlight aim. The most intense part of the headlight beam should be aimed 20 cm (8") below the mark placed on the wall. Include the weight of a rider on the seat while performing this step.
  5. If a headlight needs adjustment, locate the adjustment screw at the back of the headlight.
  6. Loosen the screw, adjust the headlight, and tighten the screw.
  7. Repeat steps 4-6 until the lamp is properly adjusted.

Brake Lights

When the brake pedal is depressed, the brake light comes on. Check the brake light before each ride.
To check the brake lights, do the following:
  1. Turn the key to the ON position.
  2. Depress the brake pedal. The brake light should come on after about 10mm (0.4 in.) of pedal travel. If the light doesn't come on, check the bulb.
