1989 Toyota CamryA little personal tip - if you get fingermarks on a halogen headlamp, you can wipe them off with rubbing alcohol (isopropyl alcohol) or, if you want to do what mechanics do, keep a number of 2X2 alcohol wipes in your automotive toolbox just to wipe off halogen headlight bulbs.HEADLAMP REMOVAL & INSTALLATIONSealed Beam HeadlampsSee Figures 2 and 3Before making a headlight replacement, make sure that the headlight switch is in the off position. 1. Loosen the screws, release the clips and remove the headlight door. To release the clips, insert a flat blade screwdriver into the jaws of the clip and pry on the jaws. 2. Remove the beam unit retaining ring screws and remove the beam unit. Fig. 2: Headlamp door clip removal 3. Compress the lock releases and disconnect the wire connector from the headlight. If the connector is tight, wiggle it while holding in the lock releases and pulling out. Fig. 3: Do not remove the adjusting screws when removing the head lamp sealed bulbNever try to loosen the aim adjusting screws. If the screws are loosened, the headlights will have to be re-aimed by a qualified technician. 4. When installing, use only a sealed beam unit with the same part number and wattage.Composite HeadlampsSee Figures 4, 5 and 6Fig. 4: Headlight bulbs are inside the sockets located in the engine compartmentFig. 5: Detach the wiring from the back of the headlamp bulbThis procedure only applies to replaceable halogen headlight bulbs (such as Nos. 9004 and 9005); it does not pertain to sealed beam units. 1. Open the vehicle's hood and secure it in an upright position.Fig. 6: Twist and pull the bulb out, but do not touch the bulb if it is still good 2. Unfasten the locking ring which secures the bulb and socket assembly, then withdraw the assembly rearward. 3. If necessary, gently pry the socket's retaining clip over the projection on the bulb (use care not to break the clip.) Pull the bulb from the socket.To install: 4. Before installing a light bulb into the socket, ensure that all electrical contact surfaces are free of corrosion or dirt. 5. Line up the replacement headlight bulb with the socket. Firmly push the bulb onto the socket until the spring clip latches over the bulb's projection.WARNINGDo not touch the glass bulb with your fingers. Oil from your fingers can severely shorten the life of the bulb. If necessary, wipe off any dirt or oil from the bulb with rubbing alcohol before completing installation. 6. To ensure that the replacement bulb functions properly, activate the applicable switch to illuminate the bulb which was just replaced. (If this is a combination low and high beam bulb, be sure to check both intensities.) If the replacement light bulb does not illuminate, either it too is faulty or there is a problem in the bulb circuit or switch. Correct if necessary. 7. Position the headlight bulb and secure it with the locking ring. 8. Close the vehicle's hood.Fig. 1 - various automotive lamps
