Match the Exact Bulb Code
Read the code on your existing bulb and check the vehicle or headlight documentation. D2R, D2S and D2H should not be treated as interchangeable. Confirm the complete code and selected variation in the listing.
Replacement HID Bulbs & Ballasts
Compare HID bulbs from Morimoto, Diode Dynamics, Osram and Philips, plus replacement ballasts for compatible systems. Browse D-series replacements and H-series retrofit options by the exact bulb type and available color temperature.
Match your existing bulb code, housing, ballast and connector before ordering. Retrofit HID bulbs are not direct replacements for halogen or LED bulbs; check each listing’s application restrictions and included components.

How to Choose HID Bulbs
Identify the lighting system already fitted to your vehicle before selecting a replacement. Bulb codes, electrical connections and ballast requirements matter as much as the chosen color.
Check Ballast and Connections
Match the bulb's specified ballast power and connector type. The listed D2H bulbs use AMP leads for compatible aftermarket ballasts, while factory-style replacements use their specified connections. A bulb-only purchase does not include a ballast unless stated.
Compare Color Options
Choose from the color temperatures offered for the exact bulb. The Diode Dynamics listings describe 4300K as warm white, 5000K as pure white and higher options as cooler tones. Check the product specifications rather than treating the Kelvin number as a brightness rating.
Confirm Application and Contents
Review housing compatibility, available space, supplied quantity and application restrictions. Some retrofit listings restrict headlight use. Check the selected product's instructions and requirements for your intended use before installation.
HID Bulb FAQs
How do I find the correct replacement HID bulb?
Check the full bulb code on the existing lamp and confirm it against your vehicle or headlight documentation. Then match the ballast, connector and selected product variation. Vehicle model alone may not identify the correct bulb when different factory headlights or retrofits are fitted.
Are D2S, D2R and D2H bulbs interchangeable?
Do not substitute them based on the similar names. The Diode Dynamics D2R listing specifies D2R replacement use and excludes D2S and D2H systems. The D2H listing uses a D2S-style base with AMP leads and is not plug-and-play with an OEM D2S system. Match the exact bulb and connection requirements.
Can an H7 HID bulb plug directly into my factory halogen wiring?
No. The Morimoto H7 XB HID listing states that the bulbs require a compatible HID ballast system and do not connect directly to stock wiring. A matching H7 designation does not establish housing or electrical compatibility. Check the listing's application restrictions as well.
Do replacement HID bulbs include ballasts?
Not unless the listing says so. For example, the Morimoto H7 XB package includes a pair of bulbs and housing pass-through cables but excludes ballasts. The Hylux product in this category is a separate pair of 35W ballasts. Check the contents of the selected item.
Can I use either a 35W or 55W ballast?
Only when the exact bulb and system support it. The Morimoto H7 XB listing specifies 35W–55W compatibility, while the Diode Dynamics D2H listing specifies compatible 35W AMP-style ballasts. Do not apply one product's power rating to every HID bulb.
Which HID color temperature should I choose?
Compare the options and color descriptions for your chosen bulb, and consider the other lamp in the pair. The listed Diode Dynamics options include warm-white 4300K and white 5000K choices, with cooler tones at higher settings. Check the specific product's output information and application requirements separately.
Are HID bulbs sold individually or as a pair?
Many listings in this category specify a pair, including the Diode Dynamics replacements and Morimoto H7 XB bulbs reviewed here. Confirm the included quantity for the exact product and variation rather than assuming every listing has the same contents.
