H4 9003 LED Headlight Bulb – All Weather Fit
When it comes to H4 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 H4 9003 bulb!
Boslla B4 H4 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 H4 9003 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.

Thomas K. (Verified Buyer) –
Product works as expected so giving a 5 star. My packaging came with no instructions. The glass bulb protector needs to be removed. I wouldnt have known if one of mine wasnt cracked.
Jannek (Verified Buyer) –
My bulbs finally arrived. I love them. Very good lighting and looks. 👍
ERIC H. (Verified Buyer) –
2001 car with yellowed plastic headlight lenses with halogen bulbs burning hotter because plastic does not effectively disperse heat. Bought new plastic headlights and Boslla 3 color LED’s.
No heat problems and, no drained battery when headlights are mistakenly left on for an hour or two. Hazardous driving conditions are reduced due to built-in lighting options.
Best of all, you see the road ahead like never before. Your old car is renewed, and you really like driving it better than
it’s younger siblings.
These are a must-have.

Hola Rosalino,
Si toma el modelo H4, lamentamos que no tenga el modo de flash de advertencia.
Para H4, tiene 6500k / 4300k / 3000k para una luz de cruce y 6500k para una luz de carretera.
Esperamos que pueda disfrutar de nuestras bombillas y agradecemos que las comparta con nosotros.

Support (store manager) –
Hi Jose,
B4 bullet is with fans and the external drive also plays a role in dissipating heat.
All our bulbs will have a one-year warranty, you can contact our customer service representatives if you have any after-sale problems.
Thank you. 🙂
