H4 9003 LED Headlight Bulb - All Weather Fit
Real Shots From Our Customers
When it comes to headlights, which color is best - yellow or white?
- The white light enlightens the street better due to its brightness than the yellow one. But white light against the snow or fog can be glaring to the eyes and it can make you tired soon.
- Yellow light was less dazzling to other drivers, and also cuts through rain, snow and fog better than white light. But it can also be harder to see with yellow lights in clear conditions.
So, which is better? The best is to have both white and yellow in one bulb!
Boslla B4 LED bulbs featured 6500k white, 4300k white-yellow and 3000k 3 colors, allowing you to change the color by switching on-off-on to fit all the road conditions.
The 6500K cool white lights offer clear vision at night, and the amber yellow lights at 4300k, 3000K with the best penetrating force, offer a clear view on rainy days, fog or snow!
If you are driving in foggy, rainy conditions daily or perhaps you live somewhere with heavy winters, these white & yellow LED bulbs are a must-buy.

Warning Canceller / Anti-Flicker [Important Note]
Please note that some vehicles (such as the 2007+ Dodge, Chrysler, Jeep, GMC, BMW, Mercedes-Bens and more) may require a set of canbus adapters to be installed.
For American vehicles, we advise the Resistor decoder, while for European vehicles, the Capacitor decoder.
To confirm if need a DECODER or not, just remove the original headlight bulb and check if the dashboard show BULB ERROR or not. If your headlights share the same bulb with DRL, there may be a flickering issue, please also try to install CANBUS adapters.
