These are small 6" LED driving lights but they sure add a lot of light to your night drive. The driving beam LED light is extremely bright at 3000lm per light. Visually the driving lens creates a seamless light whereas the spot beam has its own individual led projection. That said, you can't go wrong with either one. To make it even better, add a wireless, remote controlled relay to turn them on from the comforts of the cab without having to run any wires through the firewall. The wiring stays upfront and you get a small multi-functional remote control in your hand.
