Osram Night Breaker H4 +200 Bulbs

The previous king of the mountain H4 halogen bulbs were the Vosla H4 +190. These have just been dethroned by these. Manufactured in Germany (one of the few H4 halogen bulbs not made in Asia), deliver 250% more illumination than a standard 60w/55w H4 bulb. That's 2000% brighter with no increase in current draw or heat generated. As a result they don't require the installation of a relay kit as is required by the standard 100/55w H4 bulbs. There is one compromise - they don't last as long as standard H4 bulbs. These are a simple plug n' play replacement for your current H4 bulbs. Note: Their light is rated at 3,900 Kelvin. A 3,900K light temperature provides a bright white light with a slight warmth, making it a good upgrade over standard halogen bulbs while maintaining good road visibility in various conditions.
