Fuse melted, both HID blown. Need HELP find bulb replacement!

First I must apologize if there's another thread that has answered my predicament, I've done several searches and after an hour of reading/searching, I was not able to find a solution to my problem.

I'm needing some help with my bi-xeon HID bulb and/or kit. I bought this H4 kit from here about 2yrs ago. Both ballast has gone out on me, I have replaced both ballast since (about a year after installation). Last week the fuse on the power wire from the harness to the positive terminal on the battery melted thus causing both HID bulbs to blow. I am not exactly sure what cause the meltdown, the lights started flickering and boom, no lights. Good thing I was still in the driveway. So no lights for over a week now.

Below is my HID bulb/adapter from various angles:








My question:
This is my first HID kit so being the curious George, after unscrewing the 3 tiny star screws from the back of the bulb adapter to see if it was possible to replace just the bulb, it doesn't look possible since it's a single piece. Looks to me, you have to buy a whole new bulb w/ adapter. If this is the case, where/how can I find out/order the correct one for my truck? I would hope I don't have to buy a whole new kit just to replace the bulb? My truck is a 2005 Tacoma Crew cab.

Thank you for your feedback.

 

After seeing the fuse and that you have had to replace the ballasts multiple times I would buy a whole new kit from a reputable person.

I have had HID's for 3 years and only replaced 1 ballast and that was due to standing water and mud.

 

Hi nfs257,
I bought it from Slimcubby. While the HID lighting has been great, it's been frustrated with issues. I don't mean to be negative but the idea behind spending $140 every year or two for a whole HID system is a little ridiculous imo and/or having to constantly replace ballasts. Granted halogens cost $20 for two new bulbs and it's plug/play.

 

That was my point I havent had to buy any new items except for my own negligence. The ballast was bouncing around and sitting in mud and water which caused it to go bad.

 

It probably melted due to insufficient wire gauge or too big a fuse for that size wire and moisture is a problem too. On my old truck i cut off that cheapy fuse holder and soldering in a covered fuse holder

 

When you order the bulb from a place like TRS, it comes with the adapters. You wouldnt be able to use the bulb without them, and as you say its not easy to take apart.
