The OSRAM NIGHT BREAKER 220 H4 headlight bulbs are known for their impressive brightness, providing up to 220% more light compared to standard halogen bulbs. This can be particularly beneficial for drivers who often travel on dark or poorly lit roads, as the increased brightness and up to 150-meter long beam improve visibility and potentially reaction time for safer driving.

The bulbs emit a whiter light, enhancing nighttime clarity and making signs and obstacles easier to spot. With a color temperature providing a cooler white light, these bulbs can also give a modern aesthetic to your vehicle's lighting.

However, compatibility could be an issue; the model is not universally compatible, so it’s important to check if your vehicle supports these bulbs before purchasing. Additionally, while the bulbs offer superior brightness and a whiter light, they may have a shorter lifespan compared to standard bulbs due to the high output. If you prioritize maximum brightness for your headlights and don't mind potentially shorter durability, the OSRAM NIGHT BREAKER 220 H4 bulbs could be a great choice.
