HID Bulbs Common Questions
Vehicles with factory HID / Xenon:
If your vehicle has factory xenon (D1S D1R D2S D2R D4S D4R) choose the correct bulb above from the drop down. Remember these bulb types are sold individually (not pair).
Vehicles with composite headlights also known as halogen bulbs
Choose the correct bulb above from the drop down. These type of bulbs are sold as a pair. You get two. Remember, these bulbs require HID ballast to power them. We assume you already have these otherwise you can buy them separate.
Do your bulbs come with HID ballasts to power them?
Negative. You must buy those separate or you may already have them. Please do not think this is a complete HID conversion kit. We are only selling replacement bulbs.
I have factory halogen light bulbs, can I buy these bulbs and install them to get brighter light?
No, these HID bulbs required HID ballasts. If you do not have an existing kit, you will need to buy HID ballasts as well. We are only selling replacement bulbs.
My car has factory HID (such as Audi / BMW / Mercedes / Cadillac) and one bulb is burned out. Can I buy just 1 bulb?
First, you need to check to see if your vehicle came with factory HID / Xenon. Next, you need to test to see if indeed your bulb is burned out and NOT your ballast. Even OEM ballasts can go bad. You can do this by swapping the bulbs from one side to another. If you do decide to buy a pair of bulbs, remember, our D1S D1R D2S D2R D4S D4R are sold individually. So you recommend you buy 2 and change both so the color matches.
