Due to the limitations on the number of working hours, the various bulbs in the car head lamps often get burned-out. Cars basically have any one of the two popular designs – Some of the cars only require replacement of the smaller halogen bulb present inside the larger glass head lamp, whereas the relatively older cars require the inner bulb as well as larger head lamp to be replaced together, as they form one complete piece. For replacing car headlights, the following steps should be followed sequentially:
- Firstly determine the type of the bulb which is being used in the car before replacing car headlights. This can be achieved by opening the hood and looking behind the head lamp. A small and plastic knob on the backside of the headlamp generally implies that the replacement of the small halogen bulb is required. However, in case the headlamp is compound type, a thin metal band should be visible around the headlamp exterior. In this case, the specific procedure should be followed for replacing the entire head lamps.
- In case of the detachable halogen bulb, the black knob should be unscrewed and pulled out by pushing and turning. The halogen bulb, due to its attachment to the knob will also come out alongside automatically.
- The older bulb should be removed and the new one should be put in its place. However, the outside glass of new halogen bulbs should not be touched with fingers as the oil existing on the fingers might ruin the halogen bulb and thereby result in its complete burn out.
- The knob should be screwed in place and the new halogen bulb should then be backed into the headlamp. Subsequently, the head lamps should be tested by turning them on.
- In case, the headlamp is of the integrated type, the procedure of replacing car headlights is a tad bit different. It should be initially understood that the thin metallic band encircling the all-in-one-piece type of headlamp holds it in its right place. Moreover, such a type of car headlamp often has a three pronged connection on the rear of the headlamp, which is generally covered by a rubber piece.
- The two or four screws, which are small as well as short in size, and hold the metal band at the back of the headlamp should be unscrewed. They should however not be confused with the much longer adjustment screws.
- After securing the screws in a safe location, the metal band should be removed such that the headlamp should consequently hang in a limp manner.
- The rubber covering should be pulled back and the headlamp should be unplugged from the back itself.
- The new headlamp should be put in place of the previous one and plugged in the right manner. The rubber cover should also be put up back over the various connections again.
The metal band should also be put back on and the small screws should be screwed back into their holding position, before testing the head lamps by turning them on. Thus, the procedure of replacing car headlights can be completed in a simple and easy manner.
