REMOVAL & INSTALLATION
To replace the headlight bulb, proceed as follows:
- Open the hood.
- On 4-cylinder Odyssey models, to replace the passenger's side headlight bulb, remove the upper air filter housing.
- On V6 Odyssey models, to replace the driver's side headlight bulb, remove the upper air filter housing.
- Squeeze both ends of the headlight electrical connector to unlock the tab and carefully pull the electrical connector off.
- Carefully pull on the rubber tab to remove the weather seal.
- Unclip the wire bracket securing the bulb and pivot it away and remove the bulb.
- Installation is the reverse of removal, making sure to never touch the glass portion of the bulb. If the bulb glass has been touched, clean the glass with rubbing alcohol and a clean oil free cloth.

AIMING THE HEADLIGHTS
The headlights must be properly aimed to provide the best, safest road illumination. The lights should be checked for proper aim and adjusted as necessary. Certain state and local authorities have requirements for headlight aiming; these should be checked before adjustment is made.
Headlight adjustment may be temporarily made using a wall, as described below, or on the rear of another vehicle. When adjusted, the lights should not glare in oncoming car or truck windshields, nor should they illuminate the passenger compartment of vehicles driving in front of you. These adjustments are rough and should always be fine-tuned by a repair shop which is equipped with headlight aiming tools. Improper adjustments may be both dangerous and illegal.
The headlamps for the vehicles covered by this guide, horizontal and vertical aiming of each headlamp is provided by two adjusting wheels which move the lens assembly. The adjustment wheels are turned by using a long No. 2 Phillips screw driver. There is no adjustment for focus; this is done during headlight manufacturing.
Before removing the headlight bulb or disturbing the headlamp in any way, note the current settings in order to ease headlight adjustment upon reassembly. The high or low beam adjustment setting can be done using the wall of a garage or a building:
- Park the vehicle on a level surface, with the fuel tank about 1 / 2 full and with the vehicle empty of all extra cargo (unless normally carried). The vehicle should be facing a wall which is no less than 6 feet (1.8m) high and 12 feet (3.7m) wide. The front of the vehicle should be about 25 feet (7.6 m) from the wall.
See Figure 5
- If aiming is to be performed outdoors, it is advisable to wait until dusk in order to properly see the headlight beams on the wall. If done in a garage, darken the area around the wall as much as possible by closing shades or hanging cloth over the windows.
- Using a tape measure, measure from the ground to the center of the headlamp assembly and write down the measurement.
- Then measure the distance between the center of the grill to the center of one of the headlights and write down the measurement.
- Stand behind the center of the vehicle. If possible, use the third brake light and rear view mirror to sight the center of the vehicle. Look through the windshield, or over the vehicle toward the flat surface that is to be used to aim the headlights, and place a piece of tape on the flat surface to mark the center.
- Using the measurement taken from the center of the grill to the center of the headlamp, measure on both sides of the center mark on the flat surface and place a piece of tape on the flat surface.
- Then using the ground to headlamp center measurement, subtract 1 inch (25 mm) from the measurement, and move the two outer tape marks on the flat surface to that height.
- Turn the headlights ON low beam and note where the center of each light's beam is aimed, then switch on the high beams and note the center of each light's high beam.
- Adjust the headlights on low beam such that the light is on the center of the tape marks on the flat surface.
See Figures 6 and 7
- Have the headlight adjustment checked as soon as possible by a reputable repair shop.
