RCP - D4S6 - (A Pair) D4S/ D4R 6000K Xenon HID Replacement Bulb Diamond White Metal Stents Base 12V Car Lamps Head Lights 35W

very happy with the light output and color of the bulbs. very bright and fit perfectly. installation was easy once i was able to get my headlights out a little for clearance. but that is b/c of my car.

I have a 2014 Mazda CX-5. They have history of having headlight ballast issues. My passenger side headlight was not working, low or high beam. I ordered these cheap ones in the case I was having a ballast system issue. It turned out to just be the bulb but for the price they are bright and white to where they actually match the color of my LED fog lights. Excellent value and will eventually order some brighter ones in the long run, but I am completely happy with these for now.

Perfect price and great product

The color temperature is perfect, but the brightness isn't as good. I ended up returning these after a couple of nights of testing.

It fits my 2011 Lexus GS350 perfectly. These bulbs are the fraction of the cost. The bulbs come with white glove for installation. I highly recommend to buy them!

I got these bulbs in August 2025 by January 2026 they burst and went out. I'd reccomend looking somewhere else and save your money.

These seem to be working very well in my 2 gen Prius. Even after I bought the original Phillips brand. Hopefully, they will last. New one is on the left old one is on the right. The little white mass is what I believe indicates bulbs are going bad. Both bulbs I pulled out had this and the new ones did not. These are good and bright but, not overly so.

The reviews that were great should post video proof. I only needed 1 bulb so the left side is RCR, the right side is stock. You can’t tell customers the bulb is brighter than stock because that’s what we will look for. I rated a 3 because the bulb actually works, and the beam pattern is good. However, brighter than stock no, nor does it reach out further than stock either. I will keep this bulb until I find a product that is 5stars but in all honesty I should return it. I mean it’s $20, what did I expect. It works I’ll be happy for now

ممتاز بدرجة رهيبة

بعد التجربة جدا ممتازة

They are excellent / Great quality product. The package arrived quickly nicely packed and are identical the OEM globes. Nice bright light with tinge of blue exactly as described and fitted in two minutes. Thankyou RCP

The bulb on the right is what was replaced with the new product. It's kind of hard to tell but it is definitely brighter than the stock OEM one on the left; however, that is to say the OEM one is 10+ years old. This is definitely a bang for your buck, really easy to install, the bulbs come in a safety protection casing, which is then fitted into Styrofoam. It also came with special gloves for the installation, which is very generous! Will update in a month if it still works and/or of the brightness of the bulb.
