What to know before buying

Listing details to confirm

Listing details conflict on output: the title and feature copy state 10,000 lumens per bulb and 20,000 per set, while another details field gives 10,000LM per bulb and 20,000LM per set, but these remain manufacturer claims. The listing also calls the bulbs street legal and approved while providing no specific jurisdiction or approval documentation. Confirm the bulb size against the original bulb or vehicle manual, check local lighting rules, and note that some vehicles may require load resistors.

Who is it for?

A good fit for

Drivers whose vehicle takes an H4, 9003 or HB2 bulb and who want a stated high/low-beam LED conversion pair.
Buyers seeking an adjustable collar and willing to confirm fitment and any vehicle-specific error-warning requirements.

Less suited to

Buyers who need a fanless bulb.
Drivers who cannot verify H4/9003/HB2 fitment or need confirmed compatibility with a particular vehicle.
