Headlights

First Know and Understand About the Bulb/Headlamps:---

There are two general styles of headlamps, the sealed beam and replaceable bulb type. The sealed beam is by far the most common and includes almost all of the circular and rectangular lamps found on vehicles built through the 1980s. The sealed beam is so named because it includes the lamp (filament), the reflector and the lens in one sealed unit. Sealed beams are available in several sizes and shapes. All Honda vehicles covered in this information except the 1990-95 Accord and 1992-95 Prelude use sealed beam headlights. These latest Accords and Preludes use replaceable bulbs in fixed housings.

NOW GO THROUGH THE
REMOVAL & INSTALLATION PROCEDURE

Sealed Beams.

To understand the procedure

See Figures 1, 2, 3, 4, 5 and 6

FIG : Fig. 1: Headlamp mounting on 1984-85 Accords

Fig. 2: Headlamp mounting on 1986-89 Accords and 1984-91 Preludes

CAUTION:--- Most headlight retaining rings and trim bezels have very sharp edges. Wear gloves. Never pry or push on a headlamp; it can shatter suddenly.Go slow and do it carefully.

Some car models have popping up or spring retracting headlamps.

On cars with pop-up or retracting headlamps, turn the ignition switch OFF . Operate the retractor switch on the dash to bring the headlight doors up. The headlights should be off when the doors are up.
Remove the headlight bezel (trim).

On 1984-85 Accord, the trim involves the one piece lamp surround and corner molding.

Fig. 3: Remove the screws securing the headlight bezel

The sealed beam is held in place by a retainer and either 2 or 4 small screws. Identify these screws before applying any tools. Do not confuse the small retaining screws with the larger aiming screws. There will be two aiming screws or adjustors for each lamp. (One adjustor controls the up/down motion and the other controls the left/right motion.) Identify the adjustors and avoid them during removal. If they are not disturbed, the new headlamp should be in identical aim to the old one.
Using a small screwdriver (preferably magnetic) and a pair of needle-nose pliers if necessary, remove the small screws in the headlamp retainer.

Fig. 4: Remove the screws securing the retaining ring. Be sure not to disturb the adjusting screws

A HELPFUL TIP:---A good kitchen or household magnet placed on the shank of the screwdriver will provide enough grip to hold the screw during removal.

Remove the retainer and the headlamp may be gently pulled free from its mounts. Detach the connector from the back of the sealed beam unit and remove the unit from the car.

Fig. 5: Remove the retaining ring ...

Fig. 6: ... then unplug the connector from the back of the lamp. Be sure to transfer the rubber boot to the new lamp

Using non-AFS headlamp assembly for AFS assembly?

This query was asked for Lexus RX 330 car model.In this case the headlamp stopped working due to moisture and condensation.

The VIN number is JTJGA31U850059087.

As per this win number its not possible.

Lexus dealer suggests to replace whole headlight assembly.But the cost is Approx $1300 Plus labor charge $400.

On this details,the possibilities to solve this problem is as follows.

The only thing that is available is the adaptive road lighting system. Because of the design of the headlight for the bulbs to follow the direction on a slight turn the headlights are not interchangeable. Your vehicle identification number list two different style headlights.
One retails for $650 and one retails for $305. The reason the dealer is selling entire assembly is because without taking care of what's causing the moisture to get into the headlight you will only damage the high intensity discharge bulbs or H ID bulbs.
These are very expensive. You can dry the headlight out with a hair dryer and compressed air. The other issue that you will have even if you found someone that did not have the adaptive headlights and could make them work the electrical system would not match and would not plug into the headlight bulbs. If you're mechanically inclined you might want to try and remove the headlight dry it out with a hair dryer then use silicone sealer around all the different seams that may be leaking causing moisture to enter the headlight. If you go to www.myLexparts.com you can purchase these headlight assemblies if you need to at wholesale parts prices. You can save about 25% off the list price.

Also one more possibility
There are some online auto parts store that sell the headlight assembly that is exactly the same but without the AFS. It will fix your light issue but will not be a moving light. It appears to have the same wiring plugs as mine.
That will help.
Thanks.

Upper brake lights work,but low brake light not working?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

Basically the brake light bulb needs to be inspected.
The bulbs could still be the problem since they are double filament bulbs.If your high brake light work but not the low ones the replace the bulbs.If none in the rear work then you may need a brake light switch(on the brake pedal linkage).If this is not the case the check for power to the brake light side of the bulb and repair the broken brake light wire.
This basic inspection testing will help.Thanks.
