Plug and play kits are alright. I have them on 2 vehicles now. It will be better than stock halogen. The problem is that it can often cause safety issues for oncoming traffic by blinding them. Maybe blinding is a little harsh, more like driving with your high beams on. Plug and Play kit installs are really, and I mean really simple. I was able to install my first set in about 30 minutes and my second set in honestly less than 10. I always bought the wire relay harnesses which makes every connection a no brainer. Then you just have to attach to your battery and a ground. The hardest part is usually just getting to the back of the lights.
But no plug and play kit I have had or seen compares to a true HID light. My wife's old car had stock HID's and there is a huge difference between plug and play and stock HID.
Someone else chime in, but I believe a true HID setup is much safer than halogen in that all street signs that have reflective paint actually glow and can be seen from a much further distance.
If you have a friend that has a stock HID system on their car, see if you can get your T4R next to it and do a comparison. I really think you will be amazed.
I personally thought I could tackle the retrofit myself, but quickly realized that I don't want to ruin a pair of headlights and/or have a setup that would be no better than just doing a plug and play kit. Once I get mine from TRS, I may do my stock headlights myself(I too bought a pair of the ebay headlights in question) and see if I can sell them on here. If I do, I may try to do a DIY but don't hold me to that.
With that being said I understand Gamerc and your concerns. Sorry to come off as pushy, just really looking forward to having the lights done. I know it's a lot of money and none of us want to get ripped off. You have very valid points and I do respect them.
