Hella H71070602 Optilux XY Series HB4 9006 Xenon Yellow Halogen Bulbs, 12V, 55W, 2 Pack

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.

One of the bulbs failed after just 4 months of occasional use. Just long enough that I cannot return them. A complete waste of money.

So here's the deal.... For those of you who want HID light output, but don't have an HID equipped vehicle - STOP buying $50 bulbs, i.e. Silverstar's, PIAA's, etc. I had a nice long chat with a master mechanic at the Honda dealership here in Portland and we discussed light output on vehicles. He was very clear that the only way to increase the amount of light output from your car's stock headlights is to increase the bulb wattage. Think about it this way...in your lamp at home, if you have a 60 watt bulb in it and you replace it with a different brands 60 watt bulb, are you really expecting it to be any brighter?? Doesn't make much sense does it. Now, if you were to purchase a 100 watt bulb to replace your 60 watt bulb at home, you would expect a dramatic difference in light output correct? Exactly. This was the way he explained it to me. He also told me that although the stock bulbs do give off that ugly "yellow" hue to the color of the light output, it is technically better than the "blued" light that comes from Silverstar Ultra's. The blue filters out the yellow spectrum light which makes that nice white we all like...but here's the problem; IT FILTERS OUT THE YELLOW LIGHT. Meaning that it takes away a % of the available light, causing there to be less useable light put on to the road. So while the white is preferred, you lose actual light output....no matter what the box says. So I purchased these lights. They are 85 watts and blue...this means that while the blue may filter out some to the useable light, the wattage will more than compensate for the loss of "yellow" light. End result, my headlights (Hi's and Low's) are fantastically bright now. I will never go back to a stock wattage again. And for those of you wondering if there are any negatives to increasing bulb wattage; yes, there can be in certain vehicles. The mechanic at Honda told me that he knows for a fact that HONDA, ACURA, INFINITI, MAZDA and LEXUS have beefier wiring units that can easily handle the increase in wattage. Much of this is due to the fact that imports are highly modified with aftermarket lighting and the manufacturers take this into account when wiring the vehicles. On the other hand, He said that he has seen some fuse issues with Chevy and Ford vehicles. If you own one of these, you will need to purchase a better harness that can handle the increased wattage. I hope this helps...I searched long and hard and finally found the bulb that outperforms the "best." It looks great and puts lots of light on the road. Good Luck!

Le quedaron super bien a mi VW Gol 2009, en lo personal el color amarillo me gusta mucho , llegaron bien y en su empaque sellado , esperemos duren como los focos originales que quite y guarde , porque prácticamente se ven nuevos.

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.
