The Best HID Headlight Bulbs for Your Car's Next Upgrade: Buyers Guide

Top 9 Best HID Headlights

Before jumping into this episode of The Buyer’s Guide, a heavy dose of caution is warranted. Aftermarket HID headlights can improve nighttime vision and allow you to see farther down the road … if they’re installed correctly. And, for a lot of people, that’s a big if.

The headlamp housings in the vast majority of cars, especially ones at the Mr. Noodles end of the price spectrum, simply weren’t designed to properly reflect and refract the light produced by HID bulbs. It also doesn’t help that most amateur installs tend to end up with one headlight illuminating the Soyuz 2 spacecraft while the other searches for nightcrawlers.

Full disclosure: your handsome and multi-talented author has installed aftermarket LED lamps in his vehicles but not HIDs. With that in mind, there are plenty of knowledgeable installers who can help a car owner get the most out of their newly purchased HID conversion kit. Seek them out and listen to their advice. Avoid the minefield of dodgy kits with suspect quality, read the instruction manual, and take your time with the install.

As always, make absolutely certain the units you’re buying fit the car you own.

Updated 2/3/2021 with a new promoted product recommendation.

Yup, we’re going there. Our Editor’s Pick is one of the most expensive options selected for this buyer’s guide. With so many counterfeit and low-quality alternatives on the market, there is something to be said for choosing a trusted brand name with thousands of positive reviews.

With a color temperature of up to 4700K, these bulbs are said to illuminate the road ahead with a crisp, pure white beam that cuts through the darkness like a hot knife through butter. Its color hue should provide a great color match to stock or aftermarket LED fog lamps, an infuriating trend that is starting to pollute the roads of our nation.

The company takes great pains to infuse their product with all manner of authenticity and piracy-prevention tools. Philips purports this pair of bulbs to be fully DOT compliant since they are designed to be a direct replacement upgrade.

If you’re looking for a high-quality, high-performance lighting product at a reasonable price, XenonPro’s Xenon HID headlight conversion kits are some of the very best on the market. With a rating of up to 8,000 lumens of light output per kit, they are up to 250% brighter than stock halogen bulbs, and come outfitted with proprietary anti-glare technology to keep you blinding oncoming traffic with your new-and-improved HID headlights.

Available in 35W and 55W, these HID bulbs are built to last for up to 15,000 hours of use, or over three times that of standard halogens, and come with a market-best lifetime warranty for added peace of mind. The bulbs can also be installed in under 30 minutes thanks to their Plug-n-Play design, which mimics your OEM bulb specs, and are available in 7 different colors ranging from yellow and white to blue and purple.

XenonPro carries a kit for nearly every single car on the market with stock halogens, and even some replacement bulb kits for vehicles with stock xenons. It’s worth noting, however, that some vehicles require a piece of equipment called a warning canceller (also known as a capacitor, or CANbus decoder) in order for this product to function seamlessly. Fortunately, XenonPro has a handy list of vehicles to cross-reference if your car calls for one.

Selected from an array of options which have an acceptably high sample size of reviews, the Sylvania D1S earns many kudos from actual people who have forked over their hard-earned cash. In this day and age, decision making is becoming increasingly more social, so this metric carries weight.

This bulb carries weight, too. Its lighting is sourced from a plasma discharge rather than a filament, said to provide brighter illumination but consume less energy than bulbs of a different design. Compatible with cars that deploy D1S headlamp optics, the Sylvania unit is purported to arrive in a damage-resistant box that helps prevent issues with ham-fisted delivery drivers. Its well-known brand name doesn’t hurt its standing, either.

Fair warning – the attractive price of these bulbs is offset by the need to purchase extra-cost ballast units. Thanks to the unique properties of HIDs and how they work, a ballast kit is necessary in order for the things to operate correctly. The ballast unit is critical not only to proper illumination but also to converting your vehicle’s power supply to speak the language of HID bulbs.

Its light rating of 8000k will likely produce a medium-blue output color, a shade which may induce road rage in your fellow motorists if these bulbs are not leveled correctly. The wiring pigtails are said to be of the plug-n-play variety, designed to hook up with a compatible ballast kit with ease. The bulb design should snug itself into housings not originally designed to accept an HID bulb but be aware that the light pattern may be off if care is not taken during installation.

The names OSRAM and Sylvania can be used interchangeably even though the two rarely seem to appear side-by-each on bulb packaging. Established 25 years ago after acquiring GTE’s Sylvania lighting division, the company knows a thing or two about headlight bulbs. These units shown here fit cars with D1S-style bulbs and, in this example, are sold in pairs.

Its 4300K light rating is an OEM standard, meaning they should cast a white illumination hue, not blue. The company touts the long life of this bulb, a good thing since they are sold at the upper end of the price spectrum for this type of product. Watch for counterfeit versions of this bulb. As with tires, brakes, and denim jeans, it is a good idea to replace them in pairs.

We’re including these in our roundup because they are the cheapest we could find. These replacement bulbs cost less than most people spend on a fast-food lunch. No brand name appears on the all-black box. Reviews are all over the map, ranging from complaint-laden epitaphs to high praise.

According to the specs, these bulbs are rated at 70w for the pair and purport to heave out 7600 lumens at a bulb temperature of 8000K. This temp will assure a blue color, for better or worse. The description makes no mention of ballast but does promise each bulb was aligned with a laser (emphasis mine) during production. No one likes to throw away money but at less than the price of a good burger, it’s hard to go wrong.

Stock 55W halogen lamps can only produce about 1000 lumens of light while a 35W xenon lamp, such as this one, produces 3200 lumens of light. Basic math teaches is that’s a 300% increase. These bulbs satisfy both claims, along with being offered in all seven varieties of popular factory HID connector types.

Your author is not convinced of the seller’s argument that halogen bulbs last only 500 hours, since that translates to less than a year’s use if one is driving in the dark for two hours per day. Personal experience shows halogens last much longer than that amount of time.

Venturing into brands whose names are seemingly assembled from random words, these HID replacements are rated at an illumination of 10000K, meaning they will cast an outrageously blue light color; it’ll be almost violet in fact, bordering on purple. Take this into consideration before unholstering your debit card for these bulbs. Fitting a variety of OEM housings originally designed for HIDs, these bulbs are compatible with an array of factory fittings.

Except for the 10000K color temperature, the rest of the seller’s claims line up with the myriad of other choices in the HID replacement market. Power consumption is 35w per bulb, brightness is around 4500 lumens, and they hold an IP67 waterproof rating. In a unique addition, the product description goes on to describe the company’s production and testing process.

If it says ‘authentic’ right in the title, it must be the real deal, right? Well, we hope so. The Philips name is widely copied and counterfeited in the HID black market, a seedy underbelly of the automotive aftermarket that your author chooses to believe is populated with people clandestinely selling HID bulbs out of unmarked cases and long trenchcoats.

This seems to be the Real McCoy, with the seller stating that every genuine Philips HID bulb features a Certificate of Authentication on its packaging which can be verified through a QR code or Philip’s website. It would be more reassuring to be able to carry out this confirmation in person rather than after you’ve paid for it online.

As for the bulb, it is allegedly DOT compliant and available in no fewer than eleven different manufacturer standards, the most we’ve seen on a single product offering. Positive reviews are plentiful, many of which were posted just days before the writing of this post.

A color rating of 6000K sits squarely in the middle of the headlamp spectrum, emitting neither a stock-looking yellow nor bystander-enraging blue. With a bright white beam, drivers should be able to see farther down the road and avoid Bullwinkle before he pops out of the bush and onto the pavement. Wattage and the estimated lifespan of this lamp are all said to be well within the industry standards.

The company appears to have copy and pasted large swaths of narrative from its LED offerings, a decision which does not evoke confidence in the item shown here. A product description assembled from mildly mangled English may also give some shoppers pause.

HID Headlight Bulbs: Installation Tips and Thoughts

Gas-discharge bulbs, of which High Intensity Discharge xenons are a type, originally appeared on high-zoot machines like the Mercedes S-Class. HID lamps do not have a filament like halogen and other older-type lamps, a feature which allows them to last longer than standard bulbs.

Instead of supplying current to a filament to make it glow, an electrical arc is created between two electrodes within a xenon gas filled bulb. The lamp can only ignite when high voltage is applied. Igniting, heating, and stabilizing the arc of an HID lamp requires electronic controls, consisting of an electronic igniter and ballast.

This helps to explain why some low-quality el-cheapo conversion kits (of which there are a couple listed above) simply produce a light which dances and vibrates more than a possessed washing machine. Plunking an HID bulb into a headlamp housing originally designed for a halogen bulb can cause unexpected light patterns as well. It can certainly be done ... it just needs to be done correctly and with care.

Good HID conversion kits come with a ballast, an important piece of kit that allows your new bulb to operate in a steady and consistent manner that won’t blind oncoming traffic. Cars with existing HID bulbs are designed to accept bulbs with a built-in unit of this type. Like any other automotive lighting source, it is a bad idea to handle the bulb glass with your hands, even if you’re wearing gloves.

Unlike LED bulbs, it is a poor idea to test HIDs outside the headlight housing. Always replace the things in pairs and know that, after a couple of hundred hours of use, they will likely go through a slight color shift.
