   → Yes — any bike using an H4 socket (12V 60/55W) can accept this OEM bulb.

3. How does RAN00199/A compare with 591442/A?
   → RAN00199/A uses 60/55W H4 spec, while 591442/A is another halogen bulb spec (12V 60/55W) used in UCE models or older models. Always match your existing socket markings.

   → You can with an H4-compatible LED/HID conversion kit, but you’ll need to ensure correct beam focus and legal compliance.

9. How to verify compatibility before buying?
   → Remove your current bulb and check its base marking ‘H4’ and voltage/wattage rating. Compare to RAN00199/A before ordering.
