GT Ultra LED HB4 (Twin) at Car Bulbs Direct USA.

Why buy the GT Ultra LED Car Headlight Bulbs HB4 (Twin)?

Another brilliant entry in the the growing catalogue of the relatively new automotive lighting specialists, GT, the GT Ultra LED offers impeccable lighting performance and style in one terrific package. The GT Ultra LED is capable of producing a hugely improved light projection, up to 200% brighter than standard, while a colour temperature of 5700K allows for a highly stylised, cool white light.

Beyond the tremendous enhancements to style and light output, the GT Ultra LED offers an exceptional advantage over many LED headlight bulbs in the market by coming with a canbus adapter attached. Where fitting LED bulbs without an adapter may trigger slight flickering and dashboard error warnings, the GT Ultra LED’s clever design protects against these outcomes with a built-in resistor. This allows for you to enjoy a simple, fault-free installation, without the risk of having to buy and install additional parts.

Along with a simple installation, the GT Ultra LED promises added sight and safety with its 200% increase in light output. The GT Ultra LED headlight bulbs’ high-quality materials and precise, expert assembly, including specially selected diodes, guarantees not only a massively enhanced light output, but also a perfectly positioned beam placement. So you needn’t worry that your vastly improved light output might dazzle other drivers. On the contrary, your more striking appearance will simply alert them in advance to your presence, making for a pleasurable and safe driving experience.

And to ensure that all these fabulous benefits last as long as possible, GT have implemented heat-management technologies in the bulbs’ composition to facilitate an optimal operating temperature. This, along with the robust bulb casing, defends against extremes in temperature and enhances shock resistant. As such, you can expect the GT Ultra LED headlight bulbs to last an incredibly long time – for many years after installation.
