Headlight glass Nissan X-Trail T31 - one of the most vulnerable parts of optics, which over time becomes cloudy, becomes covered with microcracks or even breaks when hit by stones. Restoring transparency or completely replacing glass allows you to return the original light transmittance (up to 90-95% versus 40-60% for dim headlights) and avoid fines for faulty lighting. In this article we will look at how to choose the right glass, what tools you will need, and why factory sealant? Dow Corning 7091 preferable to analogues for self-replacement.
Owners X-Trail T31 (2007–2013) often encounter a problem: original glass from Nissan (article 26060-4M000 for the left headlight and 26060-4M001 for the right one) are expensive (from 8,000 ₽ per piece), and cheap Chinese analogues turn yellow after a year. We tested 5 glass options (including polycarbonate) and found the optimal price-quality ratio. Also in the article - 3 critical errorswhich lead to headlights fogging after replacement, and ways to avoid them.
Signs that your headlight glass needs to be replaced
Cracks or clouding do not always require immediate replacement. Here are the key symptoms when repairs are inevitable:
- 🔍 Visible cracks or chips more than 1 mm deep - they scatter light and create a danger for oncoming drivers.
- 💡 Constant fogging inside the headlight, which does not disappear after warming up (a sign of depressurization).
- 🌫️ Yellowish or cloudy coating, which cannot be removed by polishing (indicates degradation of the material).
- 🚨 Luminous flux reduced by 30% or more (checked with a lux meter or visually in the dark).
If the glass is just tarnished, try deep polishing using paste 3M 09374 and protective varnish Willson Glass Coat. This will return transparency for 1-2 years. But if the sealant cracks or peels, polishing is useless - replacement is required.
- Stone crack
- Cloudiness/yellowishness
- Fogging inside
- Road accident

Which glass to choose: original vs analogues
The market offers 4 types of glass for X-Trail T31:
| Glass type | Benefits | Disadvantages | Average price (per piece) |
|---|---|---|---|
Original Nissan (26060-4M000/1) |
Ideal geometry, UV protection, durability (10+ years) | High cost, long delivery | 8 000–12 000 ₽ |
| Analogue TYC (Taiwan) | Good quality, close to the original | May turn yellow after 3–4 years | 4 500–6 000 ₽ |
| Polycarbonate HELLA | Lightweight, shockproof, unbreakable | Scratched, requires protective film | 3 000–4 500 ₽ |
| Chinese analogues (no brand) | Low price, fast delivery | Poor UV protection, distorts light | 1 500–2 500 ₽ |
For long-term results we recommend original or TYC. Polycarbonate is suitable if you are ready to apply a protective coating every 2 years. Buy Chinese glass only as a last resort - they often have distorted optics, which leads to an incorrect beam of light and dazzling oncoming drivers.

Tools and materials for replacement
To work you will need:
- 🔧 Screwdriver set (cross, flat, torx
T20). - 🔥 Construction hair dryer (to soften the sealant, minimum 500°C).
- 🧴 Sealant - optimal Dow Corning 7091 (article
DC7091) or ABRO WS-904. - 🧼 Cleaner (isopropyl alcohol or Liqui Moly Kunststoff-Pfleger).
- 🛠️ Plastic spatulas for dismantling (so as not to damage the headlight housing).
- 📏 Ruler or caliper (to check clearances after installation).
Also prepare gloves (sealant is difficult to clean) and masking tape for fixing glass during drying. If you plan to paint the headlight housing, you will need ink for plastic Motip Duplicolor.
Make sure the battery is disconnected (remove the "-" terminal)
Warm up the headlight with a hairdryer around the perimeter (temperature 60–80°C)
Place cardboard under the bumper to prevent scratching
Check the integrity of the new glass (no chips/cracks)

Step-by-step instructions for replacing glass
Step 1. Removing the headlight
Remove the front bumper (unscrew the 4 bolts under the hood and 6 clips from below) or disconnect the headlight without removing the bumper (you need to unscrew the 3 bolts securing the headlight to the body and disconnect the power connector). Be careful with adjusting screws - don't lose them!
Step 2: Removing old sealant
Heat the headlight with a hairdryer around the perimeter of the glass (keep it at a distance of 5–7 cm so as not to melt the plastic). When the sealant becomes soft, carefully pry off the glass with a plastic spatula. Start from the corner - it's easier to avoid cracks. If the sealant does not yield, repeat the heating.
What to do if the glass cracks during dismantling?
If the glass breaks, do not try to remove the shards with your hands - use pliers with rubber tips. Then thoroughly clean the grooves of any remaining sealant. WD-40 and a toothpick. When installing new glass, increase the amount of sealant by 20% for reliability.
Step 3: Cleaning and Preparation
Remove any remaining sealant from the headlight housing and the new glass using isopropyl alcohol. Wipe surfaces with a lint-free cloth. Do not touch the inside of the glass - greasy marks will impair light transmission.
Step 4. Applying sealant and installing glass
Apply sealant Dow Corning 7091 a continuous line 3–4 mm thick on the headlight housing. Install the glass starting from the bottom corner and press evenly. Use masking tape around the perimeter to secure it. Leave for 24 hours for complete polymerization (at +20°C).
⚠️ Attention: If you use a cheap sealant (for example, DoneDeal), after a year the glass will begin to come off and the headlight will fog up. Saving 500 ₽ will result in repeated repairs.
Step 5: Assembly and Testing
After the sealant has dried, reassemble the headlight in the reverse order. Connect the connector and check the low/high beam operation. Adjust the light beam with the screws on the headlight housing (standard: the upper limit of the light at a distance of 10 m should be 5 cm below the height of the headlights).
Before installing the bumper, check the tightness of the headlight by spraying it with water from a hose. If moisture appears inside, repeat the procedure with sealant.
Common mistakes and how to avoid them
Even experienced craftsmen make mistakes that lead to fogging or poor light transmission. Here are the top 3 problems:
- Insufficient heating of the sealant during dismantling → the glass breaks. Solution: heat with a hairdryer for at least 5 minutes, holding at a distance of 5–7 cm.
- Saving on sealant → the headlight fogs up after a month. Solution: use only Dow Corning 7091 or ABRO WS-904.
- Touching the inside of the glass → greasy marks scatter light. Solution: work with gloves and use lint-free wipes.
Another common mistake is incorrect light adjustment after installation. If the headlight shines too high, it will blind oncoming drivers. Check the setting on level ground using adjustment screen or in the service.
Cost of work in the service vs independent replacement
Prices for replacing headlight glass in services in Moscow and regions (for 2026):
| Service type | Cost (for 1 headlight) | Opening hours | Warranty |

| Self-replacement | 1,500–4,000 ₽ (materials) | 4–6 hours | — |
Replacing yourself is beneficial if you have hair dryer, sealant and patience. However, without experience, the risk of damaging the headlight or installing the glass incorrectly is ~30%. If in doubt, it is better to contact a service with good reviews (look for Yandex.Maps or 2GIS by filter "optics repair").
The main criterion for choosing a service is availability special stand for checking the tightness of headlights. Without it, the work guarantee is meaningless.
FAQ: Frequently asked questions about replacing headlight glass
Is it possible to drive with a cracked headlight glass?
Technically yes, but it's dangerous. The crack scatters light, blinding oncoming drivers (the fine under Article 12.5 of the Code of Administrative Offenses is 500 rubles). In addition, moisture will get inside the headlight through the crack, which will lead to oxidation of the contacts and failure of the lamp.
Which sealant is better: Dow Corning 7091 or ABRO WS-904?
Dow Corning 7091 - professional sealant used in factories Nissan. It is more expensive (about 1,500 ₽ per tube), but guarantees tightness for 5+ years. ABRO WS-904 (600–800 ₽) is a good alternative for budget repairs, but may crack in 2–3 years.
Do I need to remove the bumper to replace the glass?
Not necessarily. Experienced craftsmen change the glass without removing the bumper, unscrewing only the headlight. However, it is easier for beginners to work with the bumper removed - this way there is less risk of scratching the paintwork.
How long before you can wash your car after replacing the glass?
At least after 24 hours (at a temperature of +20°C). If the sealant Dow Corning 7091, you can reduce the time to 12 hours by warming up the headlight with an incandescent lamp (keep at a distance of 30 cm for 1 hour).
Can epoxy glue be used instead of caulk?
No! Epoxy glue is not elastic and will crack when exposed to temperature changes. Headlight sealant must be heat-resistant and UV-resistant.
