LED BULB BYAKUYA BUS MARKER

Seven colors for the long night.

BYAKUYA 白夜 — “midnight sun.” Brand storytelling: OIRAN JAPAN’s LED bulb family, named for light that refuses to set.

This is the bus marker edition of the BYAKUYA LED bulb — a direct, bulb-for-bulb replacement for S25-base marker lamps on Japanese buses and trucks. Each color carries its own measured output, stated plainly: from a deep signal red at 50 lm to a clean 280 lm white, so a full roofline reads as one continuous signature.

• White 280 lm · Yellow 240 lm · Natural 230 lm · Amber 190 lm · Green 180 lm · Red 50 lm · Blue 40 lm
• S25 base (per part numbers OB21–OB27)
• Seven color-specific part numbers

Installation is a straight bulb swap into the existing socket. If the vehicle’s bulb cut-off warning appears after LED conversion, pair with an OIRAN load resistor. EU / EEA: verify local regulations before road use.
