Product Details

OEM Quality: Philips HID Bulbs; Though the 4300K come standard in many vehicles, these are the best answer for enthusiasts who demand a higher Kelvin rating (6000K) and won't settle for anything less than OEM quality in their newer D4S-based xenon headlamps.

Intense: As our best selling OEM brand, the Philips series offers a great mix of lumens, precision, and longevity to their output. Here, the 6000K produces a clean white light with a slight tinge of blue, and just under 3000 lumens/bulb at 35w.

Rare: These bulbs are hard to find! With Mercury-Free D4S Systems still being relatively new on the market

Genuine: Here at TRS, we pride ourselves on being one of the last few distributors shipping genuine Philips & Osram lamps in the US. It is estimated that 80% of these bulbs sold through outlets such as eBay or Amazon are fakes. Don't be fooled by ads offering these bulbs for anything less than $150 as there is a high chance the bulbs are cheap Chinese knock offs.

Priced Right: Doing some competitive research, the only other store offering these bulbs that are verifiably real Philips is offering them for $240. Can't beat our price!

Car guys world-wide know that TRS carries the internet's best selection of high performance automotive and powersport lighting products at the best prices, and we've got the best, most knowledgeable team of real enthusiasts to help back it up. If we sell it, then you bet we've put it to the test on our own cars, trucks, and bikes. Need a recommendation on parts for your project? Got a tech question? Wholesale inquiry? Contact Us

Another excellent experience with TRS!

David Reed Reviewed: 12.07.2017

I've purchased close to $1,000 worth of products from TRS over the years, and support, shipping, product quality, authenticity and overall service have been outstanding!

I just installed these 42402WX bulbs (42402WXX2 on the box) and I am more than satisfied! My OEM OSRAM Xenarc bulbs (4300k) were noticeably yellow, but these bulbs are a true crisp white. I've only had them for a day, but expect the burn-in to make them even better.

At start, they have a purple/blue hue, and warm to a crystal white. Visibility at night is almost identical to my OEM HIDs, so the 2500ish lumens is plenty bright for me!

Thanks again, TRS! I'll be purchasing from you again!
