Why buy the GT Ultra LED Car Headlight Bulbs H4 (Twin)?

The GT Ultra LED marks another impressive entry in the company’s growing catalogue. While issues such as flickering and poorly diffused, ‘dotted’ beams pervade the LED headlight bulb marketplace, GT’s expert design ensures a flawless projection that avoids the assembly and lighting problems of its competitors.

With an expert design that implements specially selected diodes and OSRAM Opto Semiconductors, the GT Ultra LED is able to achieve a striking light output up to 200% brighter than standard, with a highly stylish colour temperature of up to 5700K.

While the high 5700K Kelvin rating offers a modish, cool white light colour so you can drive in style, the GT Ultra LED’s massive light output allows for added safety and comfort on the road. Being up to 200% brighter than standard, the GT Ultra LED’s ice-white light not only enhances your vision, but also heightens your visibility to other drivers, protecting you and them.

Amazingly, thanks to the GT Ultra LED’s intricate heat managing construction, the bulbs’ wealth of benefits come at no cost to lifespan. Utilising a copper heat conductor and microprocessor, the GT Ultra LED is able to safely dissipate heat while effectively maintaining voltage control, meaning that you can expect thousands of hours of efficiently produced, strong LED light from your bulbs.

An enormous benefit of such an innovative design is that, unlike most LED headlight bulbs, the GT Ultra LED is self-regulating in terms of its power consumption, eliminating the bulbs’ risk of incompatibility with a vehicle’s electric wiring system. So you don’t have to worry about flickering lights or bulb error warnings on the dashboard – the bane of many LED upgrades. And with a simple, compact design and clear-to-follow instructions included, installation is a breeze.
