LED truck bulb H7 24V – high performance

The H7 LED 24V bulb is a single-filament bulb designed to replace the original halogen on 24-volt vehicles (heavy goods vehicles, trucks, buses, coaches). It is used for dipped beams or high beams. The H7 PX26d base is the most widely used standard on modern trucks (Scania, Volvo, DAF, MAN). The LED version offers a brightness of 4,000 to 6,500 lumens, with reduced consumption of more than 70% compared to halogen. At AGM Vision, our H7 LED 24V bulbs are tested to withstand vibrations and the voltage variations specific to heavy goods vehicles.

Installing an H7 LED 24V is simple and generally requires no modification to the wiring. Switch off the ignition, access the housing from the rear of the headlight, remove the original H7 halogen bulb by turning the base a quarter turn, then insert the H7 LED in the same direction. Check the beam orientation: the LEDs must be positioned horizontally (at 3 o’clock and 9 o’clock) to reproduce the correct cutoff. If your truck displays an error message, add a 24V anti-error module. The operation takes about 15 to 30 minutes per headlight.

Compatibility depends on the original base of your vehicle. Check in the technical manual or directly on the bulb in place that the format is indeed H7. AGM Vision 24V LEDs are compatible with the main brands: Scania, Volvo, MAN, DAF, Renault Trucks, Mercedes Actros, Iveco. Pay attention to the available space behind the headlamp: some LEDs are longer than halogen due to the heat sink. Measure the depth before purchase. Our product sheets indicate the exact dimensions to make your choice easier.

For a H7 LED 24V, power is measured in lumens rather than watts. A good H7 LED kit delivers between 4,000 and 6,500 lumens for lighting that is clearly superior to the original halogen (around 1,500 lm). Choose a color temperature between 5,500 K and 6,500 K for a pure white that improves visibility. Also check the type of LED chip used: CSP or Lumileds ZES chips offer a better brightness/compactness ratio. The actual power consumed by a 24V H7 LED is generally between 25 W and 55 W per bulb, depending on the models.

It depends on the electronic system of your heavy goods vehicle. Recent trucks equipped with a CAN bus (most Scania, Volvo, MAN and DAF post-2010) detect the low power consumption of the LED and may display an error warning light on the dashboard. A 24V anti-error module (or CAN bus resistor) solves this problem by simulating the power consumption of the H7 halogen bulb. Older models without onboard electronics generally do not need it. AGM Vision offers specific 24V anti-error modules suited to the most common bases.
