They appear to be a bit more “yellow” than the nokya competition. It could be more of a deeper yellow, as far as any improvement in visibility over the nokya bulb would be pure speculation. However; at $39.00 per set they are some of the most expensive replacement bulbs I’ve come across. Visibility wise the yellow doesn’t offer any extra lighting over a standard halogen because that is basically what it is with a yellow paint over the bulb.

With a HID replacement you should get substantially better visibility with a 3K HID bulb, even better visibility than a 4300K HID fog upgrade could provide. This is just based on lower kelvins = more lumens and lumens = visible light. The higher the lumens the more visiblity you will have.

Back on topic, the Hoen Endurance fogs will not offer the same light output as HID’s but to have a more JDM look you can’t beat the quality and even at $39.00 a set it’s still significantly cheaper than the leading HID replacement kits.
