FAQs
Can I return the bulbs if they don’t fit or I change my mind?
Yes. We offer a 30-day return window, even if the product has been installed (as long as it’s not damaged). Just contact our support team for return instructions.
Can I use these as both low beam and high beam?
Some models support dual-beam (hi/lo) functions, while others are single-beam only. Check your bulb size or contact us – we’ll help you choose the correct type for your vehicle.
Can I use these bulbs in projector headlights?
Yes. All of our LED bulbs are designed to work in both reflector and projector housings, but we recommend checking the beam pattern after installation for optimal alignment.
How can I contact support if I have issues?

Our team typically responds within 24 hours (business days).
Are they brighter than halogen bulbs?
Our LED bulbs output between 3600–10800 lumens per bulb, providing significantly better road visibility at night without blinding oncoming drivers.
Will these bulbs work in cold weather?
Absolutely. Our LEDs are tested to work in -40°F to 185°F (-40°C to 85°C), making them reliable in snowy, rainy, or desert conditions.
Will these bulbs fit my vehicle?
Yes – if you select the correct bulb size.
You can check your owner’s manual, look up your vehicle on our website by year/make/model, or use our Fitment Tool to find the right size. Still unsure? Contact us and we’ll help verify compatibility.
Will these blind other drivers?
No, as long as they are installed correctly and matched to your vehicle's reflector or projector housing. All our bulbs have a precise beam pattern to reduce glare and improve road focus.
Do I need a CANbus decoder?
Some vehicles, especially European makes (e.g., BMW, Audi, Mercedes), may require a CANbus decoder to prevent flickering or error messages. We offer compatible decoders to buy together.
Are these bulbs waterproof?
Yes. Our LED headlight bulbs are IP67 or higher rated, meaning they are fully sealed and resistant to dust, water, and extreme temperatures.
How long do these bulbs last?
Our premium LED headlight bulbs are rated for 50,000+ hours of use – that’s up to 5x longer than halogen. They’re built with aviation-grade aluminum and powerful fans for heat dissipation.
How do I install these bulbs?
It’s a plug-and-play installation for most vehicles.
No wiring or modification needed. Simply remove your old halogen bulbs and replace them with our LED bulbs. Installation usually takes 10–15 minutes.
Are these bulbs street legal?
HID and LED bulbs are street legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. Legal for off-road use in Snowmobile and ATV headlights and off-road racing use only auxiliary or forward lighting. International street legality varies by country. For detailed clarification, check street use.
All LED and HID bulbs from all other brands, regardless of marketing claims, are prohibited from street use in halogen headlights in the USA.

These are some the best and brightest dome LED I have ever own. Wouldn’t trade them for anything last.
Didn’t fit my application despite vehicle search. Bulb may or may not be great.

Worth the cheap cost.
