anyone in here have HID conversion kits installed? did you run into any issues with the install?

 

I installed an aftermarket HID kit with little problems. I bought the Apexcone 6000k kit from Xenonexpert.com. (They can be found on the mazda3forums.com website). The kit was plug and play. The hardest part was the damn retention clip on the headlight housing. After I figured that out, I was golden! Well worth the money too. I would say its the best money I have ever spent on any car I've owned.
Are you having issues installing one, or are you just curious because you are interested in purchasing a kit?
