The Southern Urals offers relaxation after production congestion to hold for the benefit of the home budget. Travelers using their own transport expect:
1. Fishing in remote mountain lakes all year round.
2. The collection of berries and mushrooms in the forest and meadows in the summer.
3. Hunting for birds and animals in the open season.
For lovers of outdoor activities, departing home in the dark, two points are important:
- sufficient lighting in front of the driver;
- faultless behavior of direction indicators and dimensional signals.
The on-board lighting network, including the low beam lamp (on the Chevrolet Niva, for example), will help you to overcome distances without interference, get to the pantries of the wild and return home without interference.
Seen from afar
The Russian SUV is equipped with the necessary lighting devices.
The high and low beam headlights are equipped with halogen or LED lamps.
For a long view of the night road, type H1 is used. The brightness of a glass bulb with a tungsten filament is achieved by filling with a mixture of inert and halogen gases.
Fog lights are equipped with both halogen and LED sources such as H3. The positive qualities of diode lamps are weak heating and a weak effect on vision.
In order not to blind the oncoming drivers, the headlamps use a dipped-beam lamp H7 in Chevrolet Niva.
Do not confuse direction
In addition to the head lighting devices, the machine is equipped with dimensional and rotary indicators. Front and rear turn signals are equipped with PY21W elements. In working condition, the lights burn with bright yellow light, and when turned off, they acquire a silver hue. Suitable element for tuning. After all, by car the owner will prank in the city.
The front position signal and side direction indicators work on W5W SDL devices. Since LEDs are sensitive to on-board voltage surges, the W5W is equipped with current stabilizers.
The rear position lights, lights for driving in low visibility conditions and braking signals are equipped with a P21 / 5W LED lamp with two tungsten filaments.
A single-thread P21W source is installed in the reversing light indicator.
The state license plate is illuminated with a flashlight with SDL C5W. The same products are put in the salon.
The decision of the economical driver
The power of halogen products is 55-60 watts, and for LED - 5 or 21 watts.
Landing sockets are designed for the base of incandescent lamps. So the instruments are interchangeable. But sources on diodes have the following advantages:
- A trip to the forest is an off-road route with shaking and vibration. In incandescent devices, the bulb is fragile, in LED lights it is durable.
- Incandescent lamps transfer 95% of the generated heat to the glass and base. Overheating leads to damage to the on-board network and parts of the head optics. Marker lamps C5W and W5W in the working state emit heat, but thermal energy is removed through the mounting substrate and does not affect the contacts.
Comparative characteristics are given in the table.
Indicator | unit of measurement | LN, 60W | Sdl |
MTBF | Hours | 1000 | 43,000 |
Power | Watt | 60 | 5 |
Heating temperature | ° C | 150 | fifty |
Strength | Well no | No | Yes |
freedom of choice
There are several options for arranging the low beam. You can put a halogen lamp with two threads H4, where the dipped and main beam are combined. You can install a source with one H7 thread. The third option is LED low beam lamps. In Chevrolet Niva, each of the listed devices will perform equally well functions. There is one caveat here - the price of the product.
Halogen bulbs are cheaper. For example, the cost of the Osram h7 12v 55w ranges from 230-250 rubles. The declared service life is 1 year. And in fact, it can work for 8 months and 3 years.
The time between failures of a Philips WV product is 1 year, and the cost ranges from 660 to 1300 rubles.
For car owners who value unique tuning, they produce stylish Osram h7 xenon lamps with a silver cap and a 15% brightness enhancement. The cost of an element is one and a half thousand rubles.
Functional cost
The H7 source is available in several versions. A masterpiece of design - Philips Luxeon MZ. This is a low beam lamp (Chevrolet Niva). The price of the product is 6900 rubles. The source is mounted on four diodes that increase the radiation intensity up to 4500 Lm (three times in relation to the xenon indicator). Thanks to the cut-off line, the lantern does not blind drivers in the oncoming lane. The base ring is adjustable. With a special key, the ring holder is loosened, and it becomes possible to change the position of the LEDs relative to the vertical, to focus.
To cool the lamp, technologies for removing excess energy from processors are used: a heat-conducting tube plus a radiator and a fan. The vacuum tube removes heat to the source radiator, cooled by a fan with a silent bearing. As a result, the intensity of the source glow remains even in the warm season.
In order not to burden the Chevrolet-Niva on-board network, the low-beam lamp is replaced taking into account the fact that both the halogen and LED lamps have an installed power of 55 W. Why is this important: under various loads, it would be necessary to install simulators of standard power to eliminate errors on-board computer. Once the watts are the same, then a "snag" is not required.
One can not fail to note another plus of the LED device. The fact is that it does not affect the headlight reflector. Whereas halogen lights filled with xenon lead to clouding of the reflector.
General rules for removal
A few recommendations for car owners on replacing light sources. Rules work for any type of lamp.
To change defective products, thin thread gloves are useful to the car owner. Even clean hands leave prints on the flask. Such devices are held only by metal or plastic parts. Spots reduce the brightness and life of the halogen lamp.
During installation, high pressure gas is pumped into a glass vessel. If the glass is damaged, the fragments under pressure will fly apart and cause wounds. Carefully remove the source from the socket.
Lighting troubleshooting
Situation: the driver is ready, the luggage is packed, but the Niva Chevrolet car cannot move; the dipped beam lamp does not light. All other lights are functioning. Before replacing a failed source, verification and preventive operations are required.
- Start with the diagnosis of the light button. It is useful to spend time finalizing this button, soldering an LED into the case. It will be immediately apparent whether there is contact or not.
- Continue checking for fuses and relays. Since only one lamp failed, then you can try to interchange the near relay "K4" with the distant "K5"; if after the manipulation the main beam does not turn on, then the "K4" relay must be replaced.
- Neither wires nor pads should show signs of fusion or short circuit; thorough rubbing of the contacts with alcohol is needed;
- Checking light components; if cracks or deposits are found on the bulb, the lamp must be replaced.
Checking the wiring of the on-board network is best entrusted to car service professionals. You can change the light source yourself. First, self-made work increases confidence; secondly, it reduces the cost of money and time; thirdly, there is something to talk about in the morning with colleagues.
In the Chevrolet Niva, the replacement of the low beam lamp begins with the dismantling of the old lamp:
- Remove the protective rubber cover for the headlamp.
- Disconnect the ends of the wires and the terminals of the lamp.
- Press the latch coupled to the reflector hooks from above, release from hooks and move away from the lamp.
- Pull out the defective dipped-beam source.
- Pick up a working element and fix it in place.
- Connect the ends of the wires to the terminals of the lighting device.
- Replace the rubber cover.
Finally
Fuel must be saved, and the generator must be protected. Therefore, it is wise to approach the choice of product power.
Buy light sources only with manufacturer's marking. This will guarantee that the actual performance promised on the packaging parameters.
