BYAKUYA 白夜 — “midnight sun.” Brand storytelling: OIRAN JAPAN’s LED bulb family, named for the northern night that never fully darkens.
BYAKUYA is the drop-in LED bulb line for marker and position lamps on Japanese trucks. Six variants across three bases mean the same clean light can run from cab to chassis: choose the base your lamp takes — T10 wedge, G18 or S25 — then the color: white (type 65), amber or red.
- OB01-T10S-65 — T10 base, white
- OB02-G18S-65 — G18 base, white
- OB03-S25S-65 — S25 base, white
- OB04-S25-AM15 / OB05-S25S-AM18 — S25 base, amber
- OB06-S25S-RE — S25 base, red
Installation is a straight bulb swap into the existing socket. If the truck’s bulb cut-off warning appears after LED conversion, pair with an OIRAN load resistor. EU / EEA: verify local regulations before road use.
