💡Still Running the Original 45/45W Halogen? Upgrade the Right Way.💡Pro 12V Hi/Lo LED Headlight BulbReplaces 34901-MS2-672 / 34901-MS2-671 ⬆️Visibility
Your factory 45/45W Stanley halogen was engineered decades ago.
It runs hot.It looks dull and yellow.It pulls unnecessary current.And it limits what you can see at night.
If you ride sport, tour long distance, commute daily, or use your machine for work — forward visibility is everything.
This LED is purpose-built for machines using the 12V 45/45W dual-filament headlight bulb. It preserves proper reflector geometry, maintains true high/low separation, and delivers modern brightness without electrical instability.
Replaces OEM:
• 34901-MS2-672
• Supersedes 34901-MS2-671
(OEM 12V 45/45W Stanley Halogen)

⚡ AC/DC COMPATIBILITY — WHY THIS BULB WORKS
Machines using this bulb may have:
• Battery-fed DC
• Stator-fed AC

• Flicker on AC
• Dim at idle
• Burn out early
✔ This LED runs safely on BOTH AC and DC systems.
Quick system check:
• Headlight works with key ON, engine OFF → DC
• Engine must be running → AC
Either way — this bulb is built to handle it.
