I change the bulb (9007) and it still womt work

There are only two bulbs. It is a single low/high beam bulb. They are type 9007.

Depending on how much room you have behind the headlight assembly, unplug the wire connector turn the bulb 1/3 - 1/4 turn counterclockwise and remove. when reinstalling DO NOT TOUCH THE GLASS (it is a halogen bulb) of the bulb when installing, doing so will transfer oils from your skin and cause premature failure. If you do clean the glass with rubbing alcohol and a clean cloth. If there is no room to reach in and remove the bulb, the headlight assy will probably have a couple of screws that when removed will allow you access to the bulb. BTW the part # you need is 9007

1) You will need to open the rear swing door.

2) On the inside jam there are two torx headed screws (T-15's if I remember correctly).

3) Unscrew the two torx screws.

4) The light is now held by two mounting tabs (small spherical headed plastic sets that go through a rubber grommet).

5) You will need to pry the light casing off (easy pressure with a good size flat head screw driver will do the trick).

6) The light bulbs are twist mount settings inside the light casing.

7) Twist out the mount setting, change the bulbs, and reset the light mountings.

8) To put the light casing push the light casing back on and put in the screws. Everything else will work in reverse when it comes to assembling the whole unit.

Thank you for using fixya, and good luck

The headlight on an 03 baja are a double element bulb for high an low beam. I replaced mine with 9007 bulb from auto parts store. Be careful to pay attention to bulb position, they can be installed up side down having the high beam as your low beam. I would shine the lights up against a wall or garage door and flip your high and low beams on and off to see how the shine.

Assuming you mean the bulbs and not the assembly - yes. Look under the hood in the area where the headlight is and you should see a wiring harness going onto the back of the headlight. The headlight is held in by a lock ring. Remove the wiring connector and take off the lock ring by turning it counter clockwise a fraction of a turn. Coax the bulb out (It is a 9007 bulb available at any parts house) and the installation process is the reverse. It is recommended you replace headlight bulbs in pairs - and keep the old working one as a spare.

You need a 9007 bulb

In order to change the bulb, just loosen/remove the two bolts holding the entire light assembly in (side marker, headlight and turn signal) Once these bolts are removed the entire assembly will shift / slide out away from the center of the vehicle. Once the assembly is removed you will have access to the wires/bulb.

Don't be an idiot; cost depends on where you buy it and whether you include installation by a certified mechanic.  If you can find a #2 Philips screwdriver and a car parts shop though...and I expect you don't have HID headlights...you can expect to drop $10-45 depending on the quality of the replacement.

Try replacing the bulbs in the sealed beam. Bulb #9007, do both. Lift lid, disconnect electrical wires, unlock o ring, pull out bulb. Replace bulb and reverse the order

You get to it from the engine compartment. The is a retainer that you simply twist to remove the old lamp. The old lamp will be able to be pulled apart from the wiring socket. Reverse this to install. Type 9007 bulb. Cheapest at Walmart.

This is easy. Lift the lid open. Look at the back of the sealed beam and you will see a clip and an o ring. Pull the clip up and pull wires back toward the driver's seat. Unscrew the o ring and firmly pull the bulb out toward the driver again. Note the 3 tabs on the bulb seat and realign the new bulb with those tab ( 2 bottom, 1 top). Replace with #9007 bulbs..do them both.
