Adjure designed these spot lamps to give the scooters with 5 3/4" buckets extra lighting without having to use the 4 1/2" passing lamps Harley puts on that makes it look like your running 3 headlights. These look really cool and the reflector matches the halogen bulbs we use for our Beacon Bullet lights, so they are a good match for any of our head lamps. For those that have the FLSTS Heritage Springer you can dump those 4 1/2" spots and replace it with our 3". This is a much better look. OFF-ROAD: These also work great for the off-road buggies and quad's.
