## Description

Buy DMEX D4S HID Headlight Bulbs Xenon 35W Replacement 66440 42402 42402WX Headlamp - Pack of 2, 4300K Warm White: Headlight Bulbs - desertcart.com ✓ FREE DELIVERY possible on eligible purchases

Review: Feel like new again - I replaced both low‑beam HID bulbs on my 2010 Acura TSX with these DMEX D2S 6000 K units and wow, what a difference—they’re crisp, bright, and absolutely spot on. Installation took a bit of effort, but it was worth it. Once fitted, the lights were steady, no flicker or drifts... illuminating the road cleanly without blinding oncoming traffic. At this price, it’s a great value upgrade over OEM. They’ve been in for a few weeks now with zero issues, and my nighttime visibility is better than ever. Highly recommended for TSX owners looking to restore that sharp HID glow without spending OEM prices.
Review: Perfect choice for my Audi A8 - I've had these for several months now. They are the perfect white color, very bright, with a touch of blue. I've had zero problems with them and just ordered another pair for a different car. These are so much cheaper than the OEM recommended ones and are at least as good. Highly recommended.

### ⭐⭐⭐⭐⭐ Worth the Price to Me, Even if They End Up Not Lasting Long
*by K***E on December 8, 2025*

I just recently purchased a 2007 Lexus RX350 and within a couple of weeks, I started having issues with the passenger side low beam. Found out they had the lovely Xenon bulbs with the AFS headlights. I work in parts and even with my discount, I was still going to be paying over $100 for 1 low beam, let alone 2, which I didn't have to spare at the moment. Read the reviews for these and while they are mixed, I decided for $30 it would be worth it even if they only lasted for a little while. I got help installing them (had to take off the bumper and pulled the headlight assemblies out) and they work great! I can see for a long way down the road. At this time, they have been installed for almost a month. I plan on updating after I have had them for a while to see how they faired. I will be happy if they last 6 months. I am not expecting them to compare to the longevity OEM since they are set of $30 Xenon bulbs which cost less than a third of just ONE of the Philips or Sylvania.
