Product Introduction

• Structure: Precision-injection molded from high-transmittance PC (polycarbonate) material, featuring a diamond-patterned prismatic surface for light diffusion. It has pre-drilled mounting holes and a snap-fit edge, designed to seal tightly with the lamp housing to prevent water and dust ingress.

• Performance: The PC material provides excellent impact resistance and UV stability, resisting yellowing and cracking under long-term outdoor exposure. The prismatic pattern ensures uniform light diffusion, enhancing visibility of the marker lamp while complying with road safety regulations.

Core Function

1. Light Diffusion & Visibility: The prismatic surface diffuses the light from the internal bulb to create a uniform, high-visibility marker light, enhancing the truck’s visibility to other road users.

2. Protection: Shields the internal bulb and wiring from impact, dust, and water, extending the lifespan of the lamp assembly.

3. UV & Impact Resistance: The PC material resists yellowing, cracking, and damage from road debris, maintaining optical clarity and structural integrity.

Customer Case Study – Fleet Lamp Replacement in East Africa

Earlier this year, a transport company based in Tanzania reached out to Mettlead with a recurring issue: multiple lamp on sunvisor units across their fleet of 40 Sitrak C7H tractors had failed after extended use on unpaved routes. The constant vibration had degraded the generic aftermarket lamps they had previously sourced from a local supplier.

After verifying the OEM part number—812W25260-6004—our team shipped 80 units (right and left side) within 12 days of order confirmation. The procurement manager reported that installation took less than 10 minutes per truck, and six months later, not a single replacement lamp had failed. As a result, the company now orders all Sinotruk Sitrak cab electrical components exclusively through Mettlead, citing consistent quality and competitive unit pricing as the deciding factors.

This is exactly the kind of long-term supply relationship we build with fleet operators and parts distributors worldwide.

Frequently Asked Questions – 812W25260-6004 Lamp On Sunvisor

Is the 812W25260-6004 lamp on sunvisor compatible with left-hand-drive Sitrak trucks?

Yes. This part number specifically covers the right-side (R) sunvisor lamp. It fits both left-hand-drive and right-hand-drive Sitrak cabs—the “R” designation refers to the passenger-side visor position relative to the cab layout. If you also need the left-side unit, please mention this in your inquiry so we can quote both part numbers together.

What is the expected lifespan of this sunvisor lamp under normal operating conditions?

Under standard heavy-truck operating conditions—including vibration, temperature variation, and regular on/off cycling—the 812W25260-6004 lamp on sunvisor typically lasts as long as the OEM original. Most fleet operators report 2–3 years of trouble-free performance before any replacement becomes necessary.

Does this lamp require any wiring modification during installation?

Not at all. The 812W25260-6004 uses the factory-original connector and mounting points. You simply remove the old lamp assembly and clip the new one into position. The entire process takes approximately 5–10 minutes per unit with basic hand tools.

Can I order a sample before committing to a bulk purchase?

Absolutely. Mettlead supports sample orders so you can verify fit, finish, and electrical performance before scaling up. Sample lead times are typically shorter than bulk orders, which means you’ll have a unit in hand quickly for testing.

How does Mettlead ensure quality consistency across large orders of the sunvisor lamp?
