Stock halogen bulb on passengers side on the F, yellow 3k led bulb on drivers side. Stock yellow halogens on my is300. Just a color and comparison pic of brigness/color. I ended up staying with the yellow 3k LEDs as they are wayyy brighter than stock, even though not quite as bright as the hids, but they last longer, won't ever flicker, will never need a relay kit, and less "baggage" (hids need a set of wires, a set of bulbs, and a set of ballast that all need to be hidden/installed).
