HellaH71070602 Optilux XY Series HB4 9006 Xenon Yellow Halogen Bulbs, 12V, 55W, 2 Pack

Bought these in October 2015 and one of the bulbs burn out in December 2018...3+yrs is far better than I had expected. Just purchased another pair today, so we will see if the last as long. Light output is good and the yellow is a deep, saturated color. I use them any time it is raining, snowing, foggy, or cloudy. Remember, fog lights are not to illuminate the road for yourself, they are to provide visibility of your vehicle to other drivers. They provide a great contrasting color to halogen or HID headlights to keep you safe. Looking forward to my second set.

So far they have performed above price point. Good yellow and bright light. I have them in a GS350 for fog lights. Good fitment no issues.

One of my fog light bulbs on my 330ci ZHP burnt out, so I replaced both with these. Installation was a snap: pull off the snap-in fog light bezel, remove the housing retaining bolt, and wiggle the fog light housing out of the bumper. Twist the old bulb 45 degrees to the left and remove from the housing, then replace with the new bulbs, careful not to touch the glass with your bare fingers. Easy enough. Whereas the stock lights had a pale yellowish tint to them, these are VERY YELLOW. They are almost too yellow, but they've grown on me. They are also brighter and much cheaper than the stock bulbs, so they're win-win.

I use these for low-beam in my 2004 chevy pick up. Exactly what I hoped for. Too bad for the price dropped $6 since I bought them 2 weeks ago.

These are Hella yella. Good light output, great fit, no issues.

Not as bright as i would have liked them to be.Installed on a 2011 subaru sti. my HID headlights overpower these.

*the video has a hard time capturing the “yellowness” because it looks great in person.Exactly the style I was looking for. Quality bulb that was easy to install.

I installed these on my 1997 Ford Expedition as fog lights. Amazon said that they would not fit this vehicle, but when I replaced my old stock fog lights, they are the exact same bulb (except yellow).These are definitely as bright (if not brighter) than my old fog lights. The yellow looks makes for some contrast with the white headlights and makes for less glare when the roads are wet. I also think people notice the yellow light more. I haven't had cops give me any trouble, so I'm pretty sure it is legal as long as you have white headlights to go with the yellow fogs.Also, make sure you don't touch the bulb glass, as it will shorten the lifetime of the bulb. If I have one go out I will update the review.
