16 ultra bright LEDs add extra visibility to nearly any motorcycle. While designed by BMW for BMW motorcycles this unit will attach to nearly any motorcycle that has a sturdy license plate mounting. This unit is brighter and more effective then previous LED lights. Drawing very little power, the LED light functions as an always-on running light. Then when you actuate your brake, there's a super-bright four burst flicker (the "signal-alert") which then becomes constant full brightness till you release the brake. "No worries" visibility every time. This is the same style unit used by modern BMW police motorcycles. It will not fail to get the attention of the ignorant/ sleepy/ cell phone using/ stoned/ or clinically insane motorist behind you. Did we say it was Super Bright? We couldn't take a picture of it lit up because we were afraid it would destroy the sensitive optic filters in our camera.
