Review on 💡 Hella Optilux XY Series HB4 9006 Xenon Yellow Halogen Bulbs, 12V, 55W, 2 Pack by Bryan King

I have a second set of bulbs. I use them in 2004 Matrix fog lights. The life expectancy of these bulbs is not great, so I will use a second set in two years. The first set had a blown bulb so I bought a second set (thought I had a spare bulb). The problem is that even when ordering the same part number, the color of the bulbs were different. The first set was more yellow than the second set so I had to replace both bulbs. Now 6 months later the bulb in the second set has blown so I'm left with two bulbs with the same part number but different yellow! I love how the yellow bulbs add to the car but am hesitant to buy another set.
