Review on JKCOVER LED 9006 HB4 Headlight Bulbs: Advanced CREE Chip, Fanless Conversion Kit - 80W 6000K 9600Lm (40W 4800Lm Each Bulb) by Eric Salem

**UPDATE** One of these LED bulbs failed after 5000 miles. It's not clear if this was a water leak (e.g., poor quality installation) or a manufacturer's fault. Checked last night, the area around the headlight was dry. It's currently flickering faintly, so I suspect it's something in the driver box; or the LEDs may have overheated; will find out soon. ***** Approximately the same brightness as original Osram D1S HID lamps. Was hoping for a brighter one but these work well enough and don't flicker like the old ones. The module gets very hot and I don't entirely trust the braided copper heatsinks so we'll see how long they last. beautiful in a D1S socket, whatever the cost.
