Product Description

The 40W 12V Canbus Fast-Start HID Xenon Ballast is a premium-quality replacement unit designed for stable, efficient, and reliable HID lighting performance.

Many HID ballasts are marketed as “55W” but typically operate in the 38–42W range. This unit is accurately rated at 40W ±2W, giving you the true performance you expect without inflated specifications. The result is a bright, consistent light output that ensures safe and effective night driving.

With a rated voltage of 13.5V and a 9V–16V input range, this ballast is ideal for 12V vehicles including cars and motorcycles. The integrated Canbus decoder ensures compatibility with modern on-board computer systems, preventing dashboard errors on models such as BMW, Audi, Mercedes, Volvo, Jeep, and more.

The Fast-Start function provides an instant ignition voltage of ≥23KV, allowing your Xenon bulbs to reach full brightness quickly. Built with DSP full-digital control technology, the ballast maintains steady performance, while the advanced EMI circuit eliminates electrical interference. A static testing circuit prevents false errors when restarting the engine.

Constructed with a durable alloy housing, the ballast is waterproof, dustproof, and vibration-resistant, offering long-term reliability in all driving conditions.
