So first my ballast died, so that suck, then while changing bulbs I notice the tap that holds the spring was broke. So now I don't have a headlight. What can I do?

 

sounds like you need a whole new casing.

 

If by tap you mean the small screw, you could try drilling it out and running a tap into it and using a one size larger screw. Or if the screw area cracked, plastic epoxy putty may be an option. If it comes down to it, safety wire the bulb in, making your own securing points. As far as the ballast, call up the company and get a replacement sent~unless you bought them from ebay, then you're outta luck, time to buy a new set from a good dealer like hidextra or ddmtuning. Hope this helps
