What to know before buying

Listing details to confirm

Listing details are inconsistent: the title claims 20,000LM and a two-bulb pack, while other fields list 20000 lm and 60 watts, a 120W total in feature copy, and a package quantity of 1 alongside a quantity of 2. Confirm actual per-bulb output, power and selected package contents. The claimed 500% brightness, 50,000-hour life, beam quality, CANBUS compatibility, weather performance and road legality are not independently confirmed. Verify the bulb size in your owner's manual and check vehicle fitment before purchase.

Who is it for?

A good fit for

Drivers whose vehicle manual specifies an H4/9003 bulb and who want a listed pair of LED replacements.
Buyers considering a claimed 6000K white output and plug-and-play installation, subject to confirming fitment and package details.

Less suited to

Buyers who need independently verified beam performance, road legality or vehicle-specific CANBUS compatibility.
Vehicles that do not use an H4/9003 bulb or whose fitment has not been confirmed.

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller one-star share signals that experiences are not uniformly positive. Without customer comments, the reasons are unknown. These ratings do not verify the listed brightness, beam pattern, fitment or CANBUS claims, so buyers should treat those specifications as listing claims.

Frequently asked questions

Will these fit my vehicle?

The listing describes H4/9003 compatibility and vehicle-specific fit. Check the owner's manual or existing bulb size and confirm vehicle fitment before buying.

How many bulbs are included?

The title says pack of 2 and the package detail names two H4 bulbs plus an installation manual, but another field lists a package quantity of 1. Confirm the selected listing's contents.

What brightness and power are specified?

The listing gives 20000 lm and 60 watts in its details, while feature text claims 120W total and over 20,000LM. These figures are inconsistent, so confirm the intended per-bulb and pair values.

Does it work with every vehicle without flicker or errors?

The manufacturer claims CANBUS readiness and compatibility with 99% of vehicles, but this is not confirmed for a particular vehicle. Check compatibility before installation.
