H4 LED bulbs for motorcycles. I'm not sure what specifically makes them for motorcycles, but I think they could be used in cars as well. This is a set of two. However, please note that they didn't fit my vehicle. Regarding these H4 bulbs, the heat sink at the base is thick, and it didn't fit. Please pay attention to this. Approximately 27mm in diameter. Since they are sold as a product, they may fit some vehicle models. New, unused, and in a box. ★Thank you. #★Thank you.
