Excellent lights
Color: Yellow & Spot Flood Combo
These are great lights. Put them on my side by side and they are very bright at night. They also work great in dusty environments. I would leave them on all day long riding the trails so people could see me coming in the woods easier.

More yellow then amber, was looking for more amber to cut through the fog here.

Just buy them! Incredibly bright and look cool!
Color: Yellow & Spot Flood Combo
Installed in the "ditch lights" position on my Polaris RZR 800 and use them for headlights. My stock headlights may as well be off, you can't even begin to see them in the amber light. These lights are the real deal. When I turn them off I feel like I can't see anything with the dim stock headlights. Great value. The triangle lights also look very cool.
