Key Features

12pcs 60W 7200LM Flip Clip, Much Brighter than Halogen
Boslla Bullet B4 produces a very high number of 3600lm (each bulb) in white mode, giving a total of 7200lm for a set. With a power of 30W, offering a medium-high lighting power that is brighter than 70% of the other bulbs available on the market.

360 Degrees Clocking/Rotatablity, Perfect Beam Pattern
Boslla B4 offers 100% clocking by allowing you to rotate them by 1° at a time, virtually at any angle you need, getting the perfect beam you need for best visibility. The LED chips are very small, the diodes are perfectly lined up with the original halogen bulb filament, with no dark spot, offering a perfect beam like halogen or HID.

Efficient Cooler Operation, Longer Lifespan
With the well-equipped 8500 RPM fan, even with the dust caps, the ambient temperature is also very cool, and no reason to worry. Noise isn’t an issue at only 63db, just be sure they are secure in the socket to avoid vibrations. Can last as much as 50 times longer than the typical halogen bulb’s 1000-2000 hour lifespan.

Easy Plug & Play Installation, No Modification Need
These bulbs will fit into the same socket and connect to the same wiring connector as your original bulbs. A 360° rotating design allows the bulb to be optimized to the standard pattern.

Attentions
Some cars, such as the 2007+ Dodge, Chrysler, Jeep, GMC, BMW, Mercedes-Bens, require the decoder (warning canceller)to be installed together to avoid the flicker or warning message.
To confirm if need CANBUS or not, just remove the original headlight bulb and check if the dashboard show BULB ERROR or not.
For American vehicles, we advise the Resistor decoder while for European vehicles, the Capacitor decoder.
Please contact us if you have any questions.

FAQs
Most frequently asked questions and answers
Product
The price is for a pair, meaning 2 bulbs.
You can check the bulb models HERE.
You can also refer to the vehicle owner manual or contact us with your car make/year/model. Our team will help you to choose a suitable model.
A. Boslla LED bulbs are working between 9 to 16V, but the Daytime Running light works on about 7V. So it is not recommended to install on the daytime running light because it may have a flickering with an error on the dashboard, or can't turn on.
If your vehicle's headlight bulbs have a DRL function, please ensure you turn the DRL function off and only use the headlights in the "on" position.
B. To fix the problem, you can add our capacitor/resistor to check. But we can not 100% guarantee it works.
A. The capacitor or resistor Canbus is necessary if it shows an error on the dashboard when removing the original halogen bulb.
B. If encountering the situation that the bulb does not work suddenly but works well again after turning off the power and restart it, please consider changing the dust cover with more space for heat dissipation.
