Aozoom LED Kit Bulbs H4 24V Trucks Heavy Vehicles 55W 6000K

The increase in brightness, + 390% in lumens compared to a halogen, is a parameter calculated with REAL data using an ULBRICHT sphere.

Switching from classic H4 halogens to LEDs on heavy vehicles is not only an aesthetic choice (although that icy white does look good), it directly affects safety and operating costs.

Here are the main reasons this upgrade has become standard for those covering miles at night:

1. Night-time Visibility and Safety

• The difference in brightness is dramatic. While an H4 halogen emits a yellowish light that tends to "die" on wet tarmac, the LED offers:
• Depth of field: a longer, wider light beam, essential to react in time to obstacles or animals on the road.
• White light (5500K-6000K): This colour temperature is similar to sunlight. It causes much less eye fatigue during long night shifts compared to yellow light.

2. Vibration Resistance

• Trucks are subject to constant vibrations and strong mechanical stresses.
• Halogens: They have a very thin tungsten filament which, when heated, becomes fragile. A badly taken pothole can break it instantly.
• LEDs: They are solid-state components with no moving parts or filaments. They are practically immune to vibrations, making them ideal for heavy vehicles and quarries.

3. 24V Electronics Management

• 24V truck systems can experience voltage spikes that easily burn out cheap bulbs.
• Quality truck LED kits integrate stabiliser drivers that handle fluctuations from 20V up to 64V.
• Lower consumption: An LED uses approximately 60-70% less energy than a 75W halogen, generating less heat in the original headlamp wiring.

4. Durability and Maintenance

• Replacing a bulb on a truck often requires tilting the cab or removing bulky trims.
• Halogen: Typically lasts 500-1.000 hours.
• LED: Can exceed 30.000 hours. Practically, you may never need to change them for the vehicle’s useful life.
