Bulbs constantly burn out - check what could be the reasons!

There are cars in which efficient lighting is a rare situation - usually the lamps in their lighting burn out so often that the driver does not have time to replace them. So, let's try to answer the question: what is the reason for such frequent burnout of light bulbs and how to fix it?

The average lamp life is - depending on its type and type - between 300 and 600 hours. A standard halogen lamp lasts about 13,2 hours. Bulb life is measured at 13,8V, too low for a battery. It can be assumed that the charging voltage in the car is in the range of 14,4-5 V, and minimal deviations in both directions are acceptable. And a XNUMX% increase in voltage means halving the life of the lamp.

So what influences its viability?

1) The most common mistake is to touch the light bulb glass with bare fingers when assembling. Hands are never perfectly clean, and the dirt on them easily sticks to the glass and limits the dissipation of heat, which is released in huge quantities inside the lamp bulb. This leads to overheating of the filament and significantly reduces its service life.

2) Another reason for the shortened lamp life is too high voltage in the car installation, i.e. improper operation of the voltage regulator. Halogen bulbs are sensitive to overvoltage and are destroyed when it exceeds a certain threshold. It is slightly below 15 V. Electronic voltage regulators maintain them at the level of 13,8 to 14,2 V, mechanical (electromagnetic), especially slightly "tuned" for an illusory improvement in charging, can cause this voltage to exceed 15,5 B, which will reduce the life of halogen lamps by up to 70%. For these reasons, it is worth measuring the voltage in the installation in the car with an ordinary multimeter (or ask at the workshop). It is better to do this on the lamp holder, and not on the battery terminals, then the measurement will be more reliable.

3) High temperatures are also detrimental to modern LED lighting. The LED lamp housing contains delicate electronic components that are not resistant to high temperatures. Therefore, luminaires using LED lighting must be designed in such a way that, thanks to ventilation, the heat from them can be dissipated unhindered.

4) Lamp life is also affected by external factors. Shock, vibration and vibration have a direct effect on the filament. Be sure to check its location in the headlight - it provides the desired illumination of the road and does not dazzle drivers coming from the opposite direction.

And it is better to replace car bulbs with pairs! Then we are confident that both will provide us with better visibility on the road. Check out our range at avtotachki.com and find bulbs that work in every situation!
