Headlights, they are an important aspect of everyday driving. From driving at night, during fog, during storms, or even in broad day light. We’ve come a long way since the first halogen light-bulb was introduced to the common automobile.


High Intensity Discharage (HID) lighting replaces the filament of a light bul with a capsule of gas. The light emanates an arc discharge between two closely electrodes. This discharge is hermetically sealed inside a samll quartz glass tubular capsule. HID lights require a ballast, whiach carefully regulates the voltage supplied to the capsule of gas. The amount of light produced is greater than a standard halogen bulb while sonsuming less power, this light more closely approximates the color temperature of natural daylight.

High-intensity discharge lamps (HID) produce light with an electric arc rather than a glowing filament. The high intensity of the arc comes from metallic salts that are vapourised within the arc chamber. These lamps are formally known as gas-discharge burners,[by whom?] and have a higher efficacy than tungsten lamps. Because of the increased amounts of light available from HID burners relative to halogen bulbs, HID headlamps producing a given beam pattern can be made smaller than halogen headlamps producing a comparable beam pattern. Alternatively, the larger size can be retained, in which case the xenon headlamp can produce a more robust beam pattern.[original research?]

Automotive HID may be called "xenon headlamps", though they are actually metal-halide lamps that contain xenon gas. The xenon gas allows the lamps to produce minimally adequate light immediately upon start, and shortens the run-up time.

The correlated colour temperature of factory installed automotive HID headlamps is between 4100K and 5000K[c

Some new cars on the market come equipped with the brighter HID xenon lights.  However, if your vehicle lacks this hand feature, an HID conversion kit is available for most makes and models.  HID conversion kits are your ticket to brighter lights which means better visibility and safer driving conditions.

Normal car lights are halogen, but a popular choice is a xenon HID conversion kit.  HID stands for high intensity discharge.  HID kits produce far brighter lights while using even less energy than traditional halogen bulbs.  Even if your car came with traditional halogen bulbs, xenon HID conversion kits allow virtually any vehicle to convert to improved lighting with minimal work.  Some provide HID output for high and low beams while some only work for one level of lighting.  They are available in a range of colors and anywhere from 35 watts to 90 watts!  You’ll need to know the wattage necessary for your particular vehicle.

Not only are brighter lights sometimes safer, they also improve the look of your vehicle at night.  5000K or 6000K (white and crystal white) are the most popular colors, but the lights honestly come in a vast variety of colors from pink to blue to yellow.  However, your specific light purpose and driving condition may dictate the color of light your choice.  Yellow lights are better in foggy conditions.  The ultra-bright white lights can hinder your visibility in foggy conditions.  Those ultra-bright lights do illuminate the most road ahead, so they can be especially helpful in dark driving conditions.

Electric Fuel Pumps

What Causes Low Pressure in a Fuel Pump?

The fuel pump takes the fuel from the tank and delivers it to the carburetor or fuel injection system at the required pressure. There may be various reasons for a malfunctioning fuel pump. Issues with the fuel system of a vehicle can be frustrating to no end. Sometimes, even after installing a new pump, the fuel system will not perform up to its standard. In such cases, the new pump is often blamed for not rectifying the issue. However, the actual source of the problem may be outside the fuel pump, preventing it from providing its original performance.

Fuel Pump Motor NZE-120

When the old fuel pump fails, there could be a reason for its failure other than old age. Determining this issue can help to diagnose the actual problem that is hindering the new unit's performance. Some of the common reasons for a decreased fuel performance, despite the fuel pump working fine, are explained below:

Clogged Screen Filter

The screen at the bottom of the fuel pump is the first line of defense against debris from the tank. If the screen filter is clogged, the flow of fuel will be reduced or even stopped. The filter should be cleaned or replaced, if needed.

A clogged screen filter will cause your vehicle to struggle while starting. Other engine problems due to a faulty fuel filter include backfiring, stalling and hesitation. A difficulty while accelerating is also a symptom of a bad fuel filter. A defective filter can allow your car to run smoothly up to a certain speed beyond which it causes a poor acceleration. All in all, a clogged filter will bring down the engine's efficiency.

Incorrect or Shorted Wiring

Since modern pumps are mostly electric, broken wires can cause the fuel pump to stop functioning.

Low Voltage to the Pump

The fuel pump needs a certain amount of voltage to provide an ideal and efficient performance. If the voltage delivered to the pump becomes low, the pump will not deliver the fuel at the requisite pressure. A voltage drop is often due to a bad battery or improperly-installed wires.

Cracked or Clogged Fuel Lines

If the fuel lines are cracked or clogged, the fuel pressure will drop before it reaches the engine. This in turn causes the engine to deliver a poor performance.

Failed Fuel Pressure Regulator

The fuel pressure regulator, as the name signifies, regulates the pressure of fuel delivered to the engine. If the fuel pressure regulator is failing, it may restrict the amount of fuel allowed to enter the fuel rail. This will, in turn, cause the engine to run poorly, thereby degrading the engine's performance.

Defective Fuel Pump Relay

In most cars, the fuel pump is turned on by a fuel pump relay. If the relay goes bad, it will not induce the pump to start functioning. A bad fuel pump relay often causes the engine to crank but prevents it from starting.

Empty Gas Tank

It is necessary to maintain the optimal level of fuel in the tank. If the amount of the fuel in the tank falls below a certain level, or the tank is empty, the car will not start even if all the other components in the system are working properly. Having the gas tank at least half-filled is important when you are installing a new fuel pump.

Checking these issues is a great way to ensure that the problem is being properly addressed. If the above issues are not attended to at the earliest, it can cause the fuel pump or the system to fail completely.
