Frequently Asked Questions Ask APW
How can an old headlight affect driving safety?
Answer: Old headlights that are clogged, yellowed, or cracked affect the refraction of light coming out of the lenses. These conditions will weaken the discharge of light from the lenses, which means that the illumination may seem insufficient even though the bulbs are still in tip-top shape. A weaker illumination will be unable to light up enough of the road's surface; this in turn will pose dangers to the occupants of the car and those in the oncoming vehicles. If the three signs are present in the headlights, proper cleaning and repair must be performed.
What benefits can be had if Nissan Sentra headlights are upgraded?
Answer: Nissan Sentra headlights can luckily be upgraded to provide a brighter illumination. If the model has only one bulb each for the headlight on the driver and passenger side, an additional bulb for each side can be installed to double the lighting power of the headlights. If high-power headlights are desired, the manufacturer-installed bulbs, once burned out, can be replaced instead with high-intensity discharge lamps. These ones are more efficient because they give off brighter light and consume less energy. While a headlight upgrade from halogen to HID lamps is allowed, such an upgrade must be done with caution because retrofitting the latter to the assembly of the former is hazardous. The entire assembly must be replaced, since HID lamps require a higher starting current because of their power.
What should a headlight for a Nissan Sentra have in order to be road-legal?
Answer: There are several factors that must be met in order for a Nissan Sentra headlight to be permitted on North American roads. The Land Transport Authority states that all vehicle light designs must be compliant with the Road Traffic Rules and other internationally recognized standards. First, the bulb of the headlight must emit white or visible light. Second, light intensity for low and high beam must be specific. The intensity for upper beam must be 18,000 to 60,000 candela per lamp for Type 1 lights, while the upper beam intensity is limited to 20,000 to 75,000 candela per lamp for Type 2 lights. Third, the distance of illumination must be about 1,000 feet to the front of the vehicle. Fourth, the headlight must be properly aligned to prevent distracting glare. Finally, the correct manufacturer-specified wattage must be used for the bulbs.
