New old stock, CEV Adventure Light!
Okay, these were really used on small mopeds like the Garelli Mosquito but it would totally make a great adventure light on your ADV Moped.
Mount these all over your forks. Make a quick mount with a coiled cord for a road side work light. Use this as a headlight to make the rest of your moped look HUGE.
Total width including the housing is 10.5cm.
The mount is 22mm wide.
Uses a P26s type bulb.
