Headlight glass <em>Nissan Almera G15</em>: how to choose, replace and avoid mistakes

Problems with headlight glass Nissan Almera G15: when is replacement required?

Headlight glass on Nissan Almera G15 (2012–2019) is one of the most vulnerable elements of optics. Over time, it becomes cloudy, becomes covered with microcracks, or is completely broken by stones. Even minor damage reduces light transmission by 30–50%, which directly affects the safety of night driving. Owners are often faced with a dilemma: restore old glass or install new one?

Original glass from Nissan (article 26010-BM40A for the left headlight and 26010-BM41A for the right) are expensive, but guarantee perfect fit and optical properties. Alternative options from TYC, Depo or Koito cheaper, but may have light beam distortions. In this article we will look at how choose the right glass, replace it without consequences and avoid common mistakes when polishing or sealing.

Types of glasses for headlights Almera G15: original vs analogues

There are three main types of headlight glass on the market. Nissan Almera G15:

• 🔹 Original glass - are produced Nissan or Koito (conveyor supplier). Have factory markings and certification E1 (European standard). Price: from 8,000 to 12,000 rubles. per piece.
• 🔹 Premium analogues — brands TYC, Depo, Hella. The quality is close to the original, but minor deviations in geometry are possible. Price: 4,000–7,000 rub.
• 🔹 Budget analogues - Chinese manufacturers without a brand or under brands Febi, Mega. Risk of clouding after 1–2 years, poor sealing. Price: 1,500–3,000 rub.

The key difference between the original glasses is multilayer coating, preventing condensation from forming inside the headlight. Cheap analogues often lack UV protection, which is why the plastic turns yellow after just a year of use. When choosing, pay attention to:

• 📌 Availability of a certificate E1 or DOT (for USA).
• 📌 Glass thickness - the original has 3.2 mm, budget analogues may be thinner (2.5–2.8 mm).
• 📌 Contents: the box must contain a rubber seal and fastening clips.

Step-by-step instructions for replacing headlight glass

Replacing glass with Almera G15 requires caution: errors during dismantling can lead to damage to the reflector or lamp. Average operating time — 1.5–2 hours for one headlight. You will need:

• 🔧 Screwdriver set (T20, T25, cross).
• 🔧 Construction hair dryer (for softening the sealant).
• 🔧 A knife with a thin blade or a string for cutting sealant.
• 🔧 New sealant (ABRO or Permatex for headlights).
• 🔧 Gloves and masking tape (to protect the body).

Algorithm of actions:

1. Remove the headlight: disconnect the battery terminals, unscrew the fastening bolts (2 on top and 1 on bottom) and disconnect the power connector.
2. Place the headlight on a flat surface and heat the seam around the perimeter of the glass with a hairdryer (temperature 60–80°C).
3. Carefully pry the glass with a knife or string, separating it from the body. Do not use metal tools for the lever - this may damage the reflector!
4. Remove old sealant from the body and glass with solvent (White spirit or Isopropyl alcohol).
5. Apply new sealant to the headlight housing, install the glass and secure it with tape for 2-3 hours to cure.

Make sure the battery is disconnected|Check that all tools are present|Warm up the headlight with a hairdryer before dismantling|Use only plastic tools to remove the glass|Apply the sealant in an even layer without breaking-->

After installation, check the tightness: turn on the low beam for 10–15 minutes. If condensation appears inside the headlight, repeat the procedure with the sealant.

⚠️ Attention! When replacing glass with Almera G15 with xenon (HID) do not touch the lamp bulb with your bare hands - grease marks will lead to overheating and failure of the lamp. Use gloves or a cloth.

Polishing vs replacement: which is more beneficial for Almera G15?

If the headlight glass is cloudy, but there are no cracks, it can be polished. This is cheaper than replacement, but the effect is temporary - the cloudiness will return in 6-12 months. Average cost of polishing service: 1,500–2,500 rub. for both headlights. Self-polishing will cost 300–800 rub. (paste 3M or Menzerna + sander).

When polishing is useless:

• 🚫 Deep scratches (more 0.3 mm).
• 🚫 Cracks or chips on the surface.
• 🚫 Yellowing of the plastic (indicates the destruction of the UV protective layer).

Criterion	Polishing	Glass replacement
Cost	300–2,500 rub.	RUB 1,500–12,000
Effect duration	6–12 months	3–5 years
Restoring light transmission	up to 80–90%	100%
Risk of headlight damage	Minimum	Medium (in case of installation errors)

For Almera G15 with halogen headlights polishing may be justified, but for versions with LED or xenon It is better to replace the glass immediately - distortion of the light beam after polishing worsens the illumination of the road.

Typical mistakes when working with headlight glasses

Errors when replacing or polishing glass often lead to leaks, cloudiness or incorrect operation of optics. Here are the most common:

• 🔴 Using the wrong sealant - silicone sealants (for example, "Moment") do not withstand temperature changes and crack after 1–2 years. We need specialized compounds for headlights (ABRO FS-6, Permatex 81730).
• 🔴 Overheating when drying sealant - if you use a hairdryer at maximum temperature, the glass may become deformed. Optimal mode: 60–80°C.
• 🔴 Incomplete removal of old sealant — remnants of old glue impair the adhesion of the new layer, which leads to leaks.
• 🔴 Installing glass without sealing rubber - in original headlights Almera G15 There is a rubber seal that is often lost during dismantling. Without it, the tightness is broken.

Another critical error - incorrect glass alignment. If the glass is installed skewed, the light beam shifts, which blinds oncoming drivers and impairs the illumination of the roadside. After replacement, be sure to check the headlight adjustment on a stand or using laser level.

⚠️ Attention! On Almera G15 with LED optics (restyling 2016+) the headlight glass has a special anti-reflective coating. When polishing with aggressive pastes (for example with P1500 abrasive) it wears off, which leads to light scattering and blinding oncoming cars.

Where to buy headlight glass for Nissan Almera G15: verified suppliers

When purchasing headlight glass, it is important to avoid counterfeits. It is better to order original spare parts from official dealers Nissan or in trusted online stores:

• 🛒 Official dealers - guarantee of an original part, but the price is 20-30% higher than the market. Check availability using the vehicle's VIN code.
• 🛒 Exist.ru — a large aggregator with filters by brand. You can compare prices for analogues TYC And Depo.
• 🛒 Autodoc.ru — convenient search by article, there are often discounts on premium analogues.
• 🛒 Aliexpress - only for budget glasses (the risk of counterfeiting is high, but there are reviews with photos of real parts).

When purchasing, please specify:

• 📋 Side of the headlights (left/right). On Almera G15 glasses are not interchangeable!
• 📋 Year of manufacture — pre-restyling models (2012–2015) and restyling (2016–2019) have different part numbers.
• 📋 Optics type - halogen, xenon or LED (for restyling).

How to check the authenticity of a headlight glass?

Original glass Nissan has:

1. Logo Koito or Nissan in the lower corner (laser engraving).

2. Labeling E1 or DOT at the end.

3. Packaging with a hologram and an article corresponding to the vehicle’s VIN code.

Counterfeits often do not have markings or have them in the form of a sticker (erased when washed).

Frequently asked questions about headlight lenses Nissan Almera G15

Is it possible to drive with a cracked headlight glass?

Technically yes, but this unsafe And illegally. According to the traffic regulations (clause 3.3), cracks in the optics are considered a malfunction for which the traffic police inspector can issue a fine 500 rub. or prohibit operation. In addition, the crack breaks the seal: moisture gets inside the headlight, which leads to oxidation of the contacts and failure of the lamp.

What is the difference between glass for pre-restyling and restyling? Almera G15?

On restyled models (2016+), the shape of the headlight has changed: the glass has become more streamlined, and in versions with LED an additional coating has appeared to protect against UV rays. Articles are not interchangeable:

• Dorestyle (2012–2015): 26010-BM40A (left), 26010-BM41A (right).
• Restyle (2016–2019): 26010-BM40B (left), 26010-BM41B (right).

Installing pre-restyling glass on a restyled model will lead to a loose fit and leaks.

How to remove condensation inside the headlight after replacing the glass?

Condensation appears due to a leak in the seal. What to do:

1. Warm up the headlight with a hairdryer (50–60°C) for 10 minutes - this will speed up the evaporation of moisture.
2. Check the sealant seam: if there are breaks, remove the old layer and apply a new one.
3. Use silica gel (Dehumidifier Bags): Place 1-2 bags inside the headlight before installing the glass.

If the condensation does not disappear after 2-3 days, the glass is installed incorrectly and re-sealing is required.

Is it possible to paint the headlight glass dark?

Technically possible, but illegally. According to GOST R 51709-2001, the light transmission of headlights must be at least 70%. Tinting or painting reduces this indicator, which is equivalent to a malfunction (fine 500 rub.). An alternative is to use film with a “smoky glass” effect (For example, LLumar), but its light transmittance must be no lower 85%.

How long does a headlight glass last after replacement?

The service life depends on the quality of the part and operating conditions:

• 🔹 Original glass: 5–7 years (if properly sealed).
• 🔹 Premium analogue: 3–5 years.
• 🔹 Budget analogue: 1–2 years (risk of cloudiness).

To extend service life:

• 🛡️ Wash your headlights only with a soft sponge (not with a brush!).
• 🛡️ Apply protective coating (For example, Ceramic Pro for glass).
• 🛡️ Park in the shade - UV rays destroy plastic.
