9004 LED Headlight Bulb – All Weather Fit
Real Shots From Real Customers
When it comes to 9004 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 9004 bulb!
Boslla B4 9004 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 9004 LED bulbs are a must-buy.

Much brighter than OEM. High beams have good width but not much throw distance. Alternating colors works nicely. Product itself is high quality. I watched a boslla sponsored video installation on a Jeep grand Cherokee like mine. I could not get the OEM compression ring to seat behind the bulb units. However, they have held nicely with their water seal rubber o ring in the lamp socket. There should also be an indication as which side is up. High beams need to project from above, and you can install the lamps upside down. They are very bright and light up the road ahead nicely, and seem to illuminate signage way ahead of time. I like them a lot and I’m looking forward to a 2,100 mile drive with them from Florida to Colorado after Christmas!

Boslla lights are very bright and well made. I am happy I made this decision. Upon installation of lights, I found that unfortunately one light ballast had short. I immediately contacted Boslla and they sent a replacement. I am thrilled with the easy plug and play connection lights, and the customer service. I recommend this company and will shop again for other lighting needs as my jeep build progresses.

Great speed and care on handling the order. Thank you very much.
On the quality of the headlights I’m impressed. Looks like great build quality. So far they are holding up and work great.
Only set back is the mounting ring. I’ve seen the reviews that it’s kind of loose and causes problems with clocking and sometimes falling out of the housing. So far the ones you sent me have stayed clocked and haven’t come loose in any way.
That being said, it would be great if you drilled the ring and had a set screw to tighten it in position so it doesn’t have a chance of turning out of clocking position.
The other thing with mounting these is the vehicle’s factory lock ring does not fit between Boslla housing and the slide on/off ring. In my case these are staying in place with out the vehicle lock ring and me drilling, tapping and installing a set screw.
I am planning on buying more soon for spares and other vehicles. Some of my friends and customers have noticed and asked about them and have recommended you to them.
Thank you!

Hi there,
Thank you for your kind words and we’re thrilled that you love and enjoy our bulbs.
To allow the bulbs can be adjusted 360 degrees for the best beam pattern, we designed them without screw tightened.
If there is a loose, we suggest you put the original rubber rings onto our led bulbs for a closer fit.
For any questions about our products, feel free to reach out, we’re always here and happy to help. 🥰
Again, thanks for your support of Boslla.

I would rate these a 5 but the hazard light function won’t work. That should mean it only deserves a 3 yet all three other light setting work incredibly well. I bought them on sale so I not complaining. Fill in the make, model and year, see the selection. An advisory should be posted that not all functions work with certain vehicle models. Still happy with my purchase. When they work out the kinks in the ballast technology I’ll be back for more.

Hi Daniel,
Thanks for your feedback, we feel so sorry for the 9004 bulbs at the time being no SOS modes.
