All our HPC24WY LED Bulbs

The HPC24WY bulb (also called PCY16W) is a specific base format, used mainly for the turn signals of certain recent European vehicles. This “HiPerVision” base stands out from classic formats thanks to its compact shape and its integration into design headlamps. At AGM Vision, we offer an Ultra Fit Can-bus orange LED version as a direct replacement for the original halogen bulb.

These two bases are often confused, but the HPC24WY (PCY16W) is a more compact 16 W HiPerVision format, while the PY24W is a more common standard 24 W base. They are not interchangeable: check the exact base of your vehicle before ordering. Find our HPC24WY LED bulb in our catalog if this is indeed the format you are looking for.

Yes, the replacement is direct: you just need to remove the halogen and insert the LED. Our HPC24WY Ultra Fit LED bulb is Can-bus compatible to avoid error messages on the dashboard. The installation does not require any modification to the vehicle.

No, our LED HPC24WY Ultra Fit integrates Can-bus technology that simulates the power consumption of the original halogen bulb. This avoids error messages and hyper-flashing on the vast majority of vehicles equipped with this base.

The HPC24WY (PCY16W) base is mainly fitted on high-end European vehicles, such as certain recent BMW, Audi and Mercedes models, notably for turn signals integrated into LED headlamp units. Consult your vehicle’s service booklet or the reference printed on the original bulb to confirm the base.

A natively orange LED, like our HPC24WY Ultra Fit, offers a more uniform color and a more vivid rendering than a white LED coated with an orange varnish. The varnish tends to flake over time and reduce brightness, whereas an orange LED retains its hue and power throughout its lifespan.
