Hella H71071182 Optilux XY Series 881 Xenon Yellow Halogen Bulbs, 12V, 27W, 2 Pack

The auxiliary bulbs operated exactly as described, it was my first time ordering them; went yellow instead of white. I was pleasantly surprised that a bulbs worked (evening brightness) exactly as advertised. I will be seen by oncoming traffic on the dark Hwy.

Changed out the bulbs in my Harley passing lamps and these made a nice contrast. The yellow is just enough to off set my headlamp and much brighter, easy install.

I like the Optilux Hella Yellow bulbs alot better than the white ones, because of the Foggy Nights of the Fall Season.. They work GREAT!

Excellent product. Well packaged, shipped and delivered on time. I had to return because I ordered the incorrect wattage. I will be ordering the correct bulbs that I need.

Look nice. They are little brighter than my turn signal lights but still are nice at night.

Tal cual lo ofertado, mañana las instalaré y presentaré como quedan en el vehículo Gracias

I love the color of these bulbs; I found them to be yellow enough to compliment the factory HID headlights on my car. Unfortunately, they're not durable at all. I bought these in July 2011 to replace a yellow bulb that lasted a year and a half. Since the color was an identical match, I just put one in to replace the burned out bulb and didn't do a full set replacement.That bulb lasted until about March of this year (2012). Since I had a bulb left over from this two-pack, I replaced it with the remaining sister bulb... which burned out last week. So, I still have one of the original yellow bulbs I had (going strong for over two years now) but BOTH of these burned out after a few short months. Time for me to try another brand...

The 3 prongs that mount the bulb to the reflector mount are too small, the diameter of these 3 prongs is too small, hence the light is lose and will not mount securely on the factory fog light reflector housing. Bummer...... Will try to return.I am sure they are good bulbs.
