What to know before buying

Listing details to confirm

The listing is inconsistent about output: its title says 40000LM and 200W, while the feature text says 40000LM per set and 200W, and does not independently verify the headline claim of 800% brighter. Confirm the required H4 fit and vehicle compatibility before purchase. The advertised 99% Canbus compatibility is not a guarantee for every vehicle.

Who is it for?

A good fit for

Drivers whose vehicle requires H4, 9003 or HB2 Hi/Lo bulbs and who want a listed 6000K white LED pair.
Buyers seeking a compact, halogen-size design with fan-based cooling.

Less suited to

Buyers who need independently verified brightness, wattage or vehicle-specific compatibility before choosing a bulb.

Frequently asked questions

Which bulb type does this listing specify?

It specifies H4, also identified as 9003 and HB2, for Hi/Lo beam use. Check your vehicle's required bulb type before buying.

What light output and colour are claimed?

The listing specifies 6000K white light and 40000LM per set. The title also advertises 200W and 800% brighter, but these are listing claims rather than verified measurements.

Does the package contain two bulbs?

The title says pack of 2. The supplied package inventory does not provide a separate contents list.

Is it guaranteed to work with every Canbus vehicle?

No. The listing claims 99% Canbus readiness and compatibility, which does not establish compatibility with every vehicle.
