## Questions & Answers

**Q: I bought the ds3 bulbs for my audi q5. do i need to buy the convertor harness as well?**
A: Some cars like Dodge require a resister harness as the led-type headlights use less amperage and it often causes them to flicker without.
Unless someone familiar with Audi says you need to use a aux resister harness, I would try it without and see first.
If you notice the lights seem to flicker, then add the harness.

**Q: Will this fit a 9006 connector? Thx!**
A: Actually yes. A 9005 connector will fit in a 9006. But a 9006 will not fit in a 9005.

**Q: Requiero el mismo conector para un Audi A4 2012 pero debe ser más largo ¿lo tienen?**
A: no we do not have a longer version.

**Q: I need a longer harness 24” if possible**
A: no we do not have it in 24in.
