FAQs—Chevrolet Headlight Bulb
- Is it true that the halogen bulb can burn out faster if you touch the glass with your fingers?
When you touch the glass of the new halogen bulb, oil on your fingers may be left on the quartz glass. This may have an adverse reaction, leading to the new bulb burning out prematurely, sometimes within just a few weeks after this was replaced. Instead of holding the glass, you can instead just hold it on its base, which is typically made of plastic. Or, you can use a tissue or cloth to hold the bulb or wear gloves as you install it.
- A new bulb was installed on the driver side, but the headlight still wouldn't light up when it's turned on. What could possibly be the problem? And what should be done to fix this?
If the bulb is new and has been tested to work just fine prior to installing it, you have to check the socket to see if it's loose or corroded. Spraying the corroded socket with aerosol electronics cleaner can restore the electrical connection. If this doesn't work, you will have to cut off the bad socket and then splice in a new one. When installing a bulb, dielectric grease should be applied on the socket for moisture and corrosion protection. Another thing to consider is faulty wiring in the headlight circuit.
- What are the factors affecting the lifespan of the bulb? The Chevrolet headlight bulb set burned out faster than expected. The ones they replaced lasted much longer.
The life of the bulb will not only depend on the number of hours it is used. Factors such as the temperature and climate should also be considered as heat is known to adversely affect any electrical component. The quality of the materials used on the bulb matters, too. That's why OEM bulbs may last longer. Some types of bulb are designed for maximum performance and longer life. When the vehicle is driven over pot holes, speed bumps, and rough road, engine vibration will cut its life shorter since the elements in the bulb tend to fail. Faulty installation will also cause premature burnouts.
- How long do halogen headlight bulbs last? What would be the average lifespan?
Halogen-based headlight bulbs can last anywhere between 450 and 1,000 hours. Heat has a big effect on its life. Halogen lights produce heat due to resistance. In order to produce light, electricity is directed through the filament, which resists the flow of electrons. This resistance creates heats. When the tungsten filament heats up, a part of the metal evaporates while the gas migrates to the bulb's inner surface. Despite their flaws, halogen lights are commonly used in automotive applications because they are easier to replace, they are constructed with a simpler design, they are cost-effective, and they are available in different dimensions.
- Which is a better option for headlights: LED, HID, or laser?
To find out which is a better fit for your requirements or a better match for the vehicle, you have to consider the advantages and downsides of each type of headlight. HID or Xenon headlamps have a longer lifespan than standard halogen lights. Since they consume less power and create more light, they're more efficient. However, they also produce too much glare and they're more expensive. The design is more complex. As for LED headlamps, the small size allows them to be constructed in various shapes. They consume less energy but emits brighter lighting than halogen headlights and warmer lighting than HIDs. The disadvantage is that they cost more to manufacture. They also create high temperature around the surrounding assemblies. Laser headlights, meanwhile, are energy-efficient. They are brighter than LEDs, and they come in smaller packaging. The downside is that they're not only costly but they also produce more heat than LEDs. They're not suitable for low and high beams.
