The Ultimate LED replacement headlight option for any vehicle with 7? Sealed Beam lamps. The rugged design is perfect for your Jeep Wrangler, Off-Road Vehicle, Buggies, or Classic Car/ Truck. Installation is very easy with the included H4 and H13 ?Plug and Play? connectors. Each set comes in full color retail-ready packaging and a 2-Year free Replacement Warranty. You can even choose optional colored Halos for even more customization! Improvements in brightness and reliability by adding a constant current LED driver to the main circuit board inside of the lamp to control the halos. NEW! No need for Anti-Flicker Wiring Adapters- The new SMART Integrated Can-Bus system automatically adjusts- preventing flicker issues. Increased Reliability- By conditioning the power going into the LEDs this prevents degradation which can shorten the overall lifespan of the product. Wider Input Voltage Range- The new SMD Halos can operate on a very wide voltage range from 12V-24V so that voltage spike can not damage the LEDs. Brighter LED Halos- by moving the heat load of the resistors off the PCB we are able to increase the number of LEDs on the circuit board without thermal issues. LED chips upgraded from a Cree LED to a Phillips Luxeon ZES chip.They deliver a very high efficacy 130LM/W ratio while having lower thermal output.
