CALAIS Ultra Bright H7 LED Fog Lights - 2000 Lumens, High Power COB Chips, 3000K Yellow Light - Perfect Replacement Bulbs (Set of 2) for Enhanced Visibility in Rain, Snow & Foggy Conditions

My problem with the older style led bulbs I've used in the past was that the they weren't adjustable. The driver's side E46 M3's fog lamp bulb is installed at an angle compared to the passenger's side. Previous led bulbs I used produced an uneven beam pattern and caused some glare. The Calais bulbs can be adjusted so you can aim them properly to produce an even beam pattern. I didn't expect them to be ultra bright and they aren't. But even with HIDs in the E46 M3's fog lamp housing, the light it produced wasn't as bright as they could be. This was a limitation in the fog lamps' design. Anyway, so far so good. Only time will tell how long they will last.Just an update. Following JDM Star's instruction video found on YouTube, I positioned the bulbs so that the LEDs are facing up and down in the fog light housing. As a result, I was able to gather a little more light output out of the bulbs reflected on the ground much more evenly than when I positioned the LED bulbs up and down. With the LEDs positioned up and down, the beam was uneven with less light towards the middle. Can't wait to try the 6000K version of these bulbs. And BTW, adjusting the LEDs position can't get any easier with only one screw to loosen and tighten. Just make sure you don't over tighten it as the seller suggested.This is an awesome bulb when you have limited space behind the lamp housing. Highly recommended for fog lamps as fog lamps generally don't generally throw enough light even with brighter bulbs like HIDs anyway and are only meant for illuminating the road right in front and front sides of your car. BTW, the yellow emits just enough yellow color on the ground; enough to provide contrast when you need it, while still looking yellow inside the lamps. In contrast, a 3000K HID bulb looks as yellow in the lamp housing and to color on the ground is just as yellow. To me it was a bit too much yellow on the ground so I'd rather use the Calais Golden LED bulbs.
