Sinoparcel D4S Xenon HID Headlight Bulbs - 8000K 35W High Low Beam 42402 66440 42402WX Replacement Lights- Pack of 2

04 SVT focus. I have replaced these 2xs owning the car 18.5 years. Long lasting. The 1st time I drove through a flooded road and got water in the headlight lens. That was in 2010. Just replaced both after 1 finally burnt back in April 2025. I do drive early morning and at night time most the time. Have good life on these

This replacement headlight was reasonably priced and it fit perfectly in my SUV. Ordered it one day and it came the next day as promised!!!!

Fast shipping. Super cheap and just as bright as the OEM bulbs but with a slight blue tint. Still going strong at 6 months. Will 100% buy again when the time comes

Update: Bulb Died After 1 1/2 Years. Extremely frustrating because replacing these bulbs is a pain in the butt.Perfect fit for my 2009 Mazda 6 2.5 l. OEM bulbs sell for around $150, so these are just a fraction of the cost. Well worth it. I'll be honest, it's a bit of a pain replacing the low beam bulbs on a Mazda. You have to remove the plastic body panel on the inside of the wheel well. Not completely remove it, but remove enough of the plastic clips so you can pry the panel down and reach the bulb. A couple of tips: remove the 4 screws underneath the front bumper that are holding the plastic wheel well panel in place. I watched a few YouTube videos where they we're struggling to gain access to the bulb, but removing those 4 screws makes it so much easier. Also, using a floor jack to lift the front end does give you a few more inches of much-needed clearance. Remove the round gray water tight plastic cover. You only need to rotate it a few degrees to unlock it. Next you remove the electrical boot by rotating it. There's an arrow on the boot itself which tells you which direction to rotate. After removing the boot, there's a metal clip that holds the bulb itself in place. You just have to press the clip toward the front of the car, then in toward the center of the light bulb to release it (you have to undo the clip on both the right and left side of the bulb). Then you can just let the clip flop down like you were opening a mailbox. Allowing the metal clip to flop all the way down gives you the needed clearance to easily slide the bulb in and out. These replacement bulbs came with white gloves, so you don't risk getting the bulbs dirty and having them burn out. There's quite a few YouTube videos showing how to replace the bulb, but it's such a tight space you're working in, that I didn't find any videos with good camera angles. I'm sure my steps seem confusing, but combined with a YouTube video, maybe they'll help someone out.

Buena luz pero hay que tratarla con cuidado porque es bien delicada

Thank you Amazon you saved me quite a bit of money I had went to AutoZone to purchase these lights just for one light it was going to cost $100 I went with Amazon it came with two light bulbs and I paid $28 I do recommend this product

Easy to install and quality seems ok, they work fine.

One bulb is nice and bright but has very little definition. The other bulb was so dim that I can barely see it on the garage wall; makes it difficult to see at night.
