Simplicity and performance: discover the D4S GTS 1.1 LED bulb
No more headaches with the older generations of Xenon/LED converter kits, where you had to look for the ballast and its power supply to connect the LED bulb. Simply plug in the D4S GTS 1.1 LED bulb like a classic D2S xenon bulb, thanks to your vehicle’s original connector. Our D4S LED connector is 100% compatible.
Our D4S GTS LED kit redefines brightness standards for its compact size, offering up to 7500 raw lumens, with power around 35 watts, which varies depending on your vehicle’s original ballasts. These ballasts are essential, because they determine the actual power your xenon bulbs can deliver. Be vigilant about offers and websites that promise more than 40 watts of power for D4S LED bulbs plugged into the original connector, because this is often unrealistic and inconsistent with an original installation. To exceed this power limit, it is necessary to replace your ballasts with more powerful models or to power the LED bulbs upstream of the ballast in order to avoid being limited by it. Our model, the KIT D4S THALLIUM LED BULB KIT does exactly that.
Advanced and versatile lighting: the D4S GTS 1.1 LED kit
Our LED D4S GTS 1.1 Kit, thanks to the miniaturization of electrical components, offers high power in a reduced format. Without an external box, it is particularly suitable for installations. The all-in-one GTS 1.1 LED bulb integrates an anti-error system and a voltage converter. No electrical modification is necessary. It is perfectly suited to the different electrical systems of vehicles, generating no error on the dashboard, and is 100% compatible with standard and high-end vehicles (Audi, Volkswagen, Mercedes, etc.).
Low beam: Enjoy better lighting than with a conventional xenon bulb. Our LED offers a whiter, wider, and more detailed light beam, performing up to +200% compared to 35W xenon. For an even more powerful D4S LED, choose our model LED D4S SMART V2.
High beam: The lighting of the LED D4S GTS 1.1 Kit may be slightly less bright or equivalent to an original 35W xenon in terms of distance, but it surpasses it in lighting width.
For very long-range lighting, go for our Xenon range, offering 200% more performance, with two color options: Warm White (4500K) or Pure White (5500K).
