- Will these fit my car?
- They fit vehicles that use D2S xenon bulbs, typically factory HID projector headlights. Check your owner's manual or the old bulb's stamp before ordering; D2R and D4S housings take different bulbs.
- Do I need new ballasts?
- No. These are 35W D2S bulbs designed to run on the stock HID ballast. If your ballast has failed, replacing bulbs alone will not fix the light.
- Are they really 200% brighter?
- That is the seller's claim versus standard bulbs. Expect a clear gain over aged xenon capsules, but not a switch to LED-level output.
- Is 5000K legal and good for night driving?
- 5000K is close to pure white and common in OEM xenon setups. It gives good contrast at night, though very blue-tinted bulbs can attract attention in some regions.
- How many bulbs are in the box?
- The listing describes a D2S bulb replacement; confirm the pack quantity on the buy box before ordering, since headlights need a pair for a matched beam.
- Can I install them myself?
- Yes, on most cars it is a plug-and-play swap behind the headlight housing. Avoid touching the glass capsule with bare fingers, since oils shorten bulb life.
