H11 24V truck LED bulb – The versatile heavy-duty

The H11 LED 24V bulb is a single-filament angled bulb designed for 24-volt vehicles (heavy goods vehicles, trucks, buses). It replaces the original halogen in dipped beams, fog lights or high beams. The H11 PGJ19-2 base is increasingly used on modern trucks, replacing the H7, notably at Volvo and Scania. The LED version delivers between 4,000 and 6,500 lumens, i.e. up to 3 times more than halogen, with reduced consumption of 70 to 80%. At AGM Vision, our H11 LED 24V bulbs incorporate a high-performance heat sink in order to guarantee a service life of more than 30,000 hours.

Replacing an H11 halogen with a 24V LED is done in a few simple steps. Turn off the vehicle ignition, access the headlight from the rear and unlock the original bulb. Insert the H11 LED while respecting the base orientation, then lock it. Turn on the lights to check the beam orientation: the LED chips must be positioned horizontally to ensure a correct cutoff. If the beam is poorly oriented, rotate the bulb 180°. The operation takes 15 to 30 minutes per side, without special tools in most cases.

Yes, provided that your vehicle does indeed use the original H11 base. AGM Vision H11 24V LED bulbs are compatible with the main heavy-duty truck brands: Scania, Volvo, MAN, DAF, Renault Trucks, Mercedes, Iveco. Check the available space behind the headlamp, as the heat sink may add 1 to 3 cm of depth. On trucks with a CAN bus, a 24V anti-error module may be required. Our technical data sheets detail the dimensions and compatibility for each model.

The color temperature determines the hue of the light emitted by your H11 LED 24V. Pure white (6 000 K) is the most popular: it offers excellent contrast and improves distance perception at night. Warm white (4 300 K) is closer to halogen and penetrates fog and rain better. Cool white (6 500 K) gives a more modern look, but can tire the eyes on long trips. For professional use in heavy trucks, AGM Vision recommends 5 500 K to 6 000 K, which offers the best compromise between visibility, comfort, and aesthetics.

A quality H11 24V LED bulb offers a lifespan of 30,000 to 50,000 hours, compared with about 1,000 hours for a standard halogen. This potentially represents several years of intensive use without replacement, even for a truck driving at night every day. This longevity is explained by the absence of a filament and by the integrated heat sink, which dissipates heat. AGM Vision LEDs use latest-generation chips and an electronic driver protected against overvoltage, short circuits and voltage spikes that are frequent on 24V heavy-duty vehicle networks.
