Bright yellow light
Color: Yellow & Spot Flood Combo
More yellow then amber, was looking for more amber to cut through the fog here.
They are bright though and look good
Been through quite a few storms and it’s still water proof

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.

These are BRIGHT
Color: Yellow & Spot Flood Combo, Color: Yellow & Spot Flood Combo
These are dang BRIGHT! Let’s see how they hold up over time. Using them as Ditch/Spot lights and are great. I had to buy some spade connectors to complete the install but other than that it’s easy to complete the install. I had some brackets from another company to complete my install so the fit looks great.
