Removal and replacement of headlight bulbs should be done with caution and mostly so with halogen bulbs since they have pressurized gas and will break easily when dropped. In the case of pickups, first, it is better to take off the radiator grille, the headlight bulb trim ring, and the plug connector, and replace the bulb. Another thing that should also not be overlooked is to make sure that the new bulb is firmly attached and that the trim ring has been locked safely before replacing the grille and the functioning of the headlight. In the case of MPVs, then make sure that the headlight switch is off, the negative battery cable is unplugged and the bulb assembly is removed by unlocking the locking ring. Installation of the new bulb should be done carefully without touching the glass and the battery should be reconnected to test the bulb. The procedure in the case of the Navajo is to take out the electrical connector and retaining ring, change the bulb, and check the functionality without the necessity of having to re-aim the headlamp. Good Showing of headlights is very essential in road safety and must be adjusted accordingly, preferably by a skilled person. A wall can be used to make temporary readjustments so that the beams do not shine in the incoming traffic. To aim perfectly, a vehicle should be parked at a particular distance relative to a wall, the positions of the beam should be marked and accordingly; one should make adjustments, but keep the vehicle at the same position throughout the entire procedure. The adjustment of the headlights should always be done by a reputable shop because they are safe and within the regulations.
