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.

The debris on the roads may often cause scratches as well as chips on the windshield of the cars. In such cases, the typical reaction of people is the initial inclination of getting the windshield altogether replaced. However, given the high cost of a car windshield, this might not be the most reasonable prospect and on the contrary may prove to be an unrequited expenditure for many people. Instead, it is a better idea to make use of various products available in the market, in order to aid in removal of the scratches, in a more economical manner. The various steps involved in the scratch removal from car windshields are outlined hereunder:

  • Preliminary tests should be performed on the car windshield in order to determine the location of the various scratches. In order to achieve the same, the fingernails can be used to find the exact locations wherein they catch onto the scratch. In case the scratch is considerably deep, it might not be repairable. However, if the fingernail does not get caught onto the scratch properly, it might be plausible buff it out using glass compounds and the variable speed drill.
  • The next step in order to perform scratch removal is to thoroughly clean the entire car windshield. It should be made sure that there are no unwanted elements like dirt, oil as well as debris, on the part which needs repairs.
  • Any good glass rubbing compound available in the market should be selected for the purpose of scratch removal. Moreover, they are often also available with the glass repair kits, which can be purchase online or from the local automotive shops.
  • The buffing pad should be positioned on the variable speed drill and a small quantity of the chosen glass compound should be applied on the pad. In order to remove the scratches form the car windshield, soft pressure should be applied for few minutes while working the compound onto the scratched car windshield surface in small and circular motions. It is pivotal to note that the area of the windshield which is being worked upon should be kept wet at all time, while carrying out the scratch removal procedure.
  • The area of the windshield where the scratches or the chips are being removed should be intermittently cleaned using a clean woolen rag. Consequently, a small amount of the glass polish should also be applies on a fresh buffing pad after the cleaning process is completed. The pad should be appropriately positioned in the correct place on the drill. The polish should then be worked onto the various scratches while only making use of soft to slightly moderate pressure. The process should be continued and repeated until and unless the scratch gets removed.

The option of replacing the windshield should only be considered, if the process of removing the scratches does not yield the required results, and the same remain markedly visible on the automobile windshield.
