9003 CrystalVision Ultra Upgrade Bright White Headlight Bulb, 2 Count

It wasn't until I installed a set of Cree fog/trail lights (6500K) on my V-Strom that I noticed how yellow the stock H4 headlight bulbs were. It's not surprising, since the stock headlight bulbs have a 2700K "warm white" color index, but these Philips bulbs are rated at 4000K and put out a much whiter, more neutral illumination. You can see the difference in the photo.I can't speak about their longevity at this point, but if they last a few years, I'll be completely satisfied.

Nice brightness with a warm temperature light. They lasted for a least five years until I replaced them with Fahren H4/9003/HB2 LED Bulbs. The low beams draw about 4.2 amps and high beams 4.9 amps per bulb. At 13 volts (Power = Voltage x Current), that's 54.6 watts and 63.7 watts. The LED replacements only draw 2.2 amps for the low beam and 2.3 amps for the high beams, which is less than half of these halogens. The LED have a cooler color temperature, are noticeably brighter than these halogen bulbs, but were much more difficult to install on my 2008 Toyota Tacoma.

I absolutely love the color of this bulb, its a very clean and crisp white light, no yellow of bulbs from the late 1800's and no blue of the bulbs people install to look like a spaceship or something for some reason? Just a very nice color light that is great for driving down rural roads.

They're great headlight bulbs. They're bright, they're a nice color, they're effective, and they're easy to install. The low beams are surprisingly bright. Worth the money.

These are great and the price is amazing. Saved like $30 ordering them instead of going to the parts store. And they were here in 2days. Amazing!

These were a perfect fit for my vehicle and reasonably easy to install.

Easy to install

Time will tell on how long they last. Can already tell my headlights are brighter.
