H4 Twenty20 Impact LED Headlight Bulbs - the pinnacle of LED technology

With the Twenty20 Impact Headlight Bulbs, you’ll be the envy of every other driver on the road, not to mention safer! Cheaper LED bulbs on the market can make it hard to trust the power of LEDs as headlamp bulbs - they are prone to faults, badly designed and often cause dashboard errors. But with Twenty20, you are in safe hands. They have worked to innovate the technology to a new level, and all of that work is on display in the Impact bulb

Avoid the hassle of warning codes

The majority of cars and motorcycles have Canbus, a system which tells you when something has gone wrong. With many LED bulbs, they lack the Canbus technology to be compatible with the car's system, and that can mean error messages and non-functioning lamps. The Impact bulb is different - it is the most compatible Canbus system seen on the market yet, offering warning avoidance in 9/10 vehicles. Even if you don't manage to get rid of those pesky error messages, Twenty20 also offers a range of decoders for extra sensitive systems here.

A beam pattern to die for

Older LED 'headlight' bulbs boast about impressive beam patterns and light output, but often they only produce a blob of flickering light. Not Twenty20! The Impact range offers a safe and powerful beam pattern that is suitable for normal road use. Your cars' dipped beam headlights are designed to shine the light as far as possible without causing glare, and this is exactly what the Impact is built to do - shine brighter, further & whiter without becoming a distraction.

Instant perfection

LED are an instant on-and-off lighting solution, making them perfect for the road where every second counts. In under a second, the Impact bulb will go from inactive to full intensity, lighting your way on any road. Stay safer in the dark or on dangerous roads!

Crystal white for maximum Impact

With plain halogen bulbs, you may find a horrid murky yellow light coming from your headlamp. Not with LEDs, and certainly not with the Impacts! The Impact bulb shines a beautiful icy white, which not only looks better but shines brighter on the road. Safety and style, all in one!

Guaranteed to last

And the cherry on top - Twenty20 offers a 3-year guarantee on every Impact bulb. You’ll never be without a light to guide you on the road!
