What to know before buying

Listing details to confirm

The listing title claims 6500K and 64000LM, while the specifications state 6000 Kelvin, 6000K White and a maximum output of 6500 lumens. These output and colour-temperature details are inconsistent, so confirm the intended figures before purchase. Its universal-fit and almost-99%-compatibility claims do not confirm fitment for a specific vehicle. Check the owner’s manual or original bulb size. The listing also says some sensitive vehicles may need an additional CAN bus decoder, which is not confirmed as included. The 80,000-hour life and five-minute installation are manufacturer claims.

Some customers report bulbs that did not last, including one reported failure after nine months, and feedback is mixed on reliability, design and flickering. The listing claims an 80,000-hour operating life and a five-minute installation, but those claims do not settle reported durability concerns or ensure a straightforward fit in every vehicle.
