We recommend the LLHD lamp for the following cases:
When your vehicle is equipped with daytime running lights, your lamps will have a shorter lifespan. This means not in terms of hours of illumination, but rather in terms of perceived lifespan compared to a vehicle without daytime running lights.
If you have a vehicle where the headlight receives a lot of shocks and vibrations (especially motorcycles), equipping your car, motorcycle, or scooter with an LLHD bulb can prevent premature burnout of the bulb.
A third case can be recent cars that often have headlights where replacing a burned-out lamp proves to be a real hassle.
And of course, if you simply want lamps with a longer lifespan.

This lamp functions as a low beam or high beam. It is a single-filament lamp. The H1 is often used for the other light. It is also a single-filament lamp.

This model is also available in 55W standard
