Crossover owners Nissan Murano second generation (Z51 body) are often faced with the need to update lighting equipment. With age, halogen lamps lose their brightness, and standard yellow light no longer provides adequate visibility on the highway. Replacing a light source is not just a change of consumables, but an opportunity to significantly improve the safety of a night trip.
The replacement process may seem complicated due to the dense layout of the engine compartment and the presence of electronic control systems. However, knowing the type of base and the features of the electrical circuit, you can do the work yourself in 20-30 minutes. It is important to understand the difference between low and high beam, and also take into account the nuances of working with lensed optics.
In this article we will look in detail at what kind of light bulbs are installed on different modifications. Nissan Murano Z51, how to change them correctly and what errors may occur when installing modern LED solutions. We will also look at issues with the CAN bus, which often blocks new light sources without special windings.
Types of bases and lighting range Murano Z51
Car lighting system Nissan Murano The Z51 is built on time-tested standards, but has its own characteristics depending on the market and year of manufacture. The main focus should be on headlights, where combined high and low beam solutions are used.
For low beam, most configurations use lamps with a base H7. They are screwed directly into the lens body and provide a clear cut-off line. High beam is often implemented through a separate lamp or duplicated by the same H7, depending on the specific firmware version of the control unit.
- 💡 Low beam: standard base H7 (12V 55W)
- 💡 High beam: the same one is often used H7 or separate H1
- 💡 Fog lights: specific base HB3 (9005) or H11
- 💡 Side lights: W5W (T10) or H15 (depending on year)
Reverse and brake lights also require attention. Rear optics often use double helices or separate contacts for different operating modes. Errors in the selection can lead to the fact that when reverse gear is engaged, the brake lights will light up, which is unacceptable from the point of view of traffic regulations.
Step-by-step instructions for replacing low beams
Access to headlights Nissan Murano The Z51 is limited, especially on the driver's side where the washer reservoir and suspension components get in the way. To replace a low beam lamp you will need a minimum set of tools and a little patience.
First, open the hood and locate the rubber plug behind the headlight. It has a diameter of about 6-7 cm and is fixed by turning it 90 degrees. Remove it carefully so as not to damage the clips, as new ones may be fragile due to the aging of the plastic.
☑️ Preparation for replacement
Next, disconnect the electrical connector by pressing the latch. Remove the lamp by turning the socket counterclockwise. It is important here not to touch the glass bulb of the halogen lamp with your fingers, as oil from the skin will cause local overheating and rapid failure.
Install the new light source, making sure that the tabs on the base line up with the grooves in the housing. This is critical for the correct formation of the light beam. After installation, return the rubber plug to its place and check the tightness of the connection.
Correct orientation of the lamp during installation ensures correct operation of the lens and no glare for oncoming drivers.
Features of fog lights and dimensions
Fog lights on Nissan Murano Z51s are located low in the bumper and require removal of part of the protective shield or access through the wheel arch. The type of lamp in the PTF is often different from the head light, which creates confusion when ordering spare parts.
A situation often occurs when a standard PTF lamp burns out, and the owner installs an analogue with the wrong base. This results in impossible installation or poor contact. Make sure you are using exactly HB3 or H11, as specified in the instruction manual.
- 🔧 To access the PTF, you may need to remove the fender liner or the lower part of the bumper
- 🔧 Replacement of dimensions is carried out through the top access in the engine compartment
- 🔧 When installing LEDs in PTF, check for the presence of resistors
Side lights are the easiest to change. It is enough to remove the plug from the inside of the headlight and replace the W5W type lamp. However, if you have a restyled model, there may be a more complex lamp with two contacts, which cannot be replaced with a regular analogue without modifications.
⚠️ Attention: When replacing lights with LEDs, make sure they have a wide beam pattern, otherwise you will blind drivers in the rearview mirrors.
CAN bus problems and installation of LED lamps
Modern cars including Nissan Murano Z51 are equipped with a CAN bus system that monitors the integrity of the lighting circuit. When installing light-emitting diode lamps (LED) instead of halogen lamps, the computer may record an error due to the low resistance of the diodes.
This manifests itself in blinking turn signals or an error light on the dashboard. To avoid this, it is necessary to use lamps with already built-in resistors or install external decoders (windings) for each channel.
If you decide to install LED headlights, be aware of the risk of blinding oncoming traffic. Lensed optics Murano designed for a specific focal point of the filament, which the diode does not have.
Why might LED lights flicker?
The vehicle system checks the circuit resistance. A halogen lamp has a resistance of about 2-3 ohms, and an LED lamp has a resistance of less than 0.5 ohms. The controller perceives this as an open circuit and turns on emergency mode, causing the relay to click or the lamp to flash.
Correct operation of LEDs in low beam headlights often requires the use of special models with Can-compatible electronics. Regular cheap diodes will work unstably and can damage the light control unit.
Ignoring CAN bus errors can lead to the entire lighting channel being turned off and the computer refusing to control the headlights without diagnostics.
Comparison table of lamp characteristics
For clarity, we have collected data on the different types of lamps that can be used in a car Nissan Murano Z51. Comparison will help you choose the best option for your tasks and budget.
| Lamp type | Base | Power | Color temperature | Service life |
|---|---|---|---|---|
| Halogen (Stock) | H7 | 55 W | 3200K (Warm) | 500 hours |
| Xenon (Optional) | D2S | 35 W | 4300 K (Neutral) | 2500 hours |
| LED | H7 (Adapted) | 25-30 W | 6000 K (Cold) | 15000 hours |
| Dimensions | W5W | 5 W | 3200 K | 10000 hours |
Please note that installing xenon in lenses not intended for it is strictly prohibited by law and is technically impractical. Such headlights provide uneven light and blind other road users.
LEDs win in terms of energy consumption and durability, but lose in quality of light spot if they do not have ideal crystal geometry. Only high-quality LED modules with an accurate imitation of filament provide safe light in the Murano Z51 lensed optics.
Troubleshooting common problems
Sometimes the problem is not in the lamp itself, but in the contacts or wiring. Oxidation of the connector may result in the new lamp not lighting up or operating intermittently. Inspect the contacts for carbon deposits or corrosion.
If the error message appears after replacing the lamp, but the light works fine, the problem may be a software glitch. In some cases, resetting errors through the OBD-II diagnostic scanner, which clears the memory of the light controller, helps.
- 🛠️ Check the fuses in the mounting block before replacing lamps
- 🛠️ Clean the connector contacts with alcohol or contact fluid
- 🛠️ Make sure the lamp is inserted all the way into the socket
When replacing lamps in the rear optics, be careful with the plastic fasteners. The fragile plastic can crack if not handled carefully, requiring replacement of the entire headlight section or complex repairs.
⚠️ Attention: Never turn on the headlights immediately after installing LED lamps without checking the polarity, unless they have built-in reverse polarity protection.
Before purchasing new lamps, be sure to remove the old one and check the markings on the base with the catalog number, since configurations may differ in different markets.
Results and recommendations for choosing
Selecting lamps for Nissan Murano The Z51 depends on your priorities: maximum brightness, economy, or meeting factory standards. Halogen remains the most reliable and cheapest solution, but LED wins in comfort when installed correctly.
Do not skimp on the quality of lamps, especially in headlights. Cheap analogues often have incorrect filament or crystal geometry, which turns the headlight into a source of blinding light. It is better to buy a quality brand once than to change cheap lamps every six months.
Remember that proper lighting is the key to your safety and the safety of others. Regularly check the functionality of all lamps and promptly replace burnt-out elements.
High-quality replacement lamps are not only aesthetics, but also a critical element of the active safety of the car.
What kind of low beam lamps are installed on the Nissan Murano Z51?
Most trim levels of the Nissan Murano Z51 use 55 W H7 bulbs for low beam. However, some versions may have a combination lamp or a specific socket, so it is recommended to check the owner's manual for your specific year of manufacture.
Is it possible to install LED headlights on a Murano Z51?
Technically, it is possible to install LED lamps, but this requires the use of special models with the correct radiation geometry and decoders for the CAN bus. Incorrect installation can lead to blinding oncoming drivers and fines from the traffic police.
Why does the lamp blink after replacing it with an LED one?
Flashing is caused by a circuit resistance mismatch. The car sees the diode resistance below the standard value and interprets this as a malfunction (break). To eliminate this, it is necessary to install additional resistors (windings) or use lamps with built-in adaptation.
How often do you need to change lamps on Murano Z51?
The service life of halogen lamps is about 500-1000 hours, which usually corresponds to 2-3 years of active use. LED lamps can last up to 15-20 years, but their performance depends on the quality of cooling and electronics.
