LASFIT L Series bulbs have an impressively bright, rich light output with a modern style. The traditional incandescent bulbs can't change from yellow to white, but LED can. The switchback function gives your car an amazing look between the white and amber modes.

-Key Feature-

Dual Color Switchback Design
Light up 6000K white for driving light/DRL; 3000K flash amber for turn signal lights. The turn signal flashes "amber-off-amber-off," which makes it easier to see.

Excellent Heat Dissipation Construction
LASFIT bulbs use built of lightweight and high-strength aluminum alloy as bulb body to keep themselves cool, even if they're used in constant-on applications like daytime running lights, they still illuminate non-fading brightness. Some bulbs, which were covered in many LED chips will haven't enough cooling surfaces.

Polarity Free + -
You needn't worry whether you have a CK or Non-CK socket, these bulbs are universally compatible. They will fit into the same socket as your OEM original bulbs.

Built-in Constant Current IC Driver
A constant current driver is a device that takes any incoming voltage and smooths it out, regulates it, so a steady stream of voltage/current reaches the LED, ensures a bright, efficient and long-lasting illumination.

Worry-Free Warranty
We provide 45 days money-back guarantee, 1-year hassle free warranty, professional and friendly customer service, and U.S. local support.

Best Customer Service!!!
The Lasfit crew consistently provides excellent service. When I faced an issue with one of my switchback running lights not transitioning from yellow to white, I ordered a replacement pair and left a brief note explaining the situation. Lasfit's customer service promptly refunded my purchase and sent a new pair at no cost. With their quick arrival and easy installation, the new lights performed perfectly. If you're deciding where to invest your business, opt for Lasfit – you won't be disappointed.

Side note: The lights appear to be flashing or flickering in the video but that is due to the camera NOT the lights!!!

So far I love the lights. They put out a ton of white light and the amber switchback is plenty bright as well.

I did have one issue. The first time I installed the passenger side light, it lit up white no problem, but wouldn’t blink at all. Not even with the hazards activated. I removed them, rotated them 180* and reinstalled. Worked perfectly after that. I don’t know if there’s an issue with that bulb, but it is working well so far. The issue with the bulb not blinking at first is the only reason I bumped these down to 4 stars. I will update this if the bulb works perfectly for the rest of its life or fails in days/weeks.
