Why I should or should not do retrofit

Retrofit all-day. There will not be a plug-in-play item currently on the market that will give you as much visibility nor blind oncoming drivers than this. I've never been high-beamed because of my retrofits. My brother-in-law put a set of cree led bulbs meant for halogen headlights in my sister's car and it's bright for her, but it's still somewhat blinding because of the spray from the stock halogen lights. Retrofits don't have hotspots. The light output in front of you is uniform. No joke, I feel safer/more confident driving my T4R at night now. The stocks were horrible and the brakes don't help.

I paid $251.62 for the entire setup from TRS. I didn't get halo's though nor did I black out the headlights. I'm 50/50 on regretting not doing both. I was going for a stock look at the time with just better output and mods to bring my car from a 2001 to something a decently packaged 2016 would have.

It is easily my favorite mod/upgrade I have done to date and I've done quite a bit in the last year. My last car had stock HID's and I'd say these are just as good. My last rental car in November was a new Ford Explorer and that was only slightly better. If the explorer was a 10, the retrofit is a 9.5. I could tell when I came back home to my T4R but it was still great. I felt as though my T4R lights were ever so dimmer than the ford's but the coverage was the same. Don't let that detract you though because compared to stock, I'd rate stock at 3.

Until you do it or see it in person, no one here is going to be able to explain how much better you see at night. If you know someone that has a car with factory HID's, drive their car at night. That's what it will be like. It's a really easy project with some basic tools, just set aside some time and double check your work before you seal them back up. It took me maybe 5 hours to do but only because I had to do it 5 times. 2x on each light because I shut them without the wire from the bixenon plugged in. A 3rd time because I got a "new to me" toyota headlight from eBay for $45 to replace an aftermarket one that was on the car because it could no longer be adjusted.

I was looking at all types of stuff prior and decided I would rather go with a trusted vendor that I would have no issues with warranty exchanges with. I chose 4500k for best visible output. I've used 8000k and 6000k in the past. In hind sight, I'd probably try 6000k to match my sidemarker LED's better. Side by side, they're more blue so it irks me.

Worth it

I very recently built mine on a budget of $200, with rgb halos and everything (see pictures in my garage) a lot of people say they took a lot of hours or even a few days to do... but I finished painting and retrofitting mine in about 3 hours, granted I did probably about 20 hours of research beforehand, plus they look amazing, and are 10x brighter than my stock lights. I've also driven past about 10 cops this week alone with green halos turned on, and not one even turned a head at me.
 
My favorite mod is my retrofit with fx-r projectors. I would rather have the projectors than my icon suspension. The difference in light output is insane and any vehicle I purchase from here on I will be retrofitting. In fact the first modification to my wife's sequoia will be retrofits.
I was worried about the vibrations off-road, but after 2,000 miles off-road with speeds 60+ over washboard roads I have not had a single issue with my lights

California Motor Vehicle Code has no specific, posted statement regarding HID headlamps on a vehicle but rather seems to defer to Federal DOT standards regarding vehicle illumination requirements.

I found the following statements on a private law group's website, LegalBeagle.com:
HID headlights are not explicitly outlawed under California law. The state's vehicle code requires headlamps to distribute light that is white or yellow in color. HID headlights that emit a blue light are illegal in the state. HID lights are also legal in California, and elsewhere in the country, if they meet the safety standards of either the U.S. Department of Transportation or Federal Motor Vehicle Safety Standards, which is typically indicated on the equipment. However, some HID headlight manufacturers have falsely claimed their lights have DOT approval. Even if a vehicle's HID lights are white or yellow, they could still be illegal under federal law if they include aftermarket modifications that don't utilize the vehicle's existing light source.​

Most vehicle manufacturers utilize 4300K lights as these produce the best overall visibility in both clear and inclement conditions. I found that 5000K produces a clear, crisp white that works well for the desert driving that I do and I have passed 100s of highway patrol cars in 3 states with both my halos, and projectors on. Not one cop has shown interest in my lights; yet. The CA DMV does have a statement regarding fog lamps on a vehicle, no more than two. That's all I could find online.

This all may be anecdotal at best, but food for thought for CA drivers or any other state's that defers to DOT regulations. YMMV

Just a little comment from me...

The D2S 4.0s are unreal. They put my FX-Rs to shame, especially the cutoff on the brights.
 
I did the budget retrofit to my stock 99 housings. With the amazon.com projectors, h1 conversion, and ddm 5k hid bulbs I am in at 120 bucks. I didn't do any fancy painting to the inside of the housing. I also didn't add any halos. The light output is a nice clean white and provides a great amount of controlled light. One of my best mods, and it looks stock to the common citizen that doesn't own a 3rd gen.
 
I want to do a retrofit for the huge improvement in light output, but at the same time it is nice not having to worry at all about anything going wrong with my current headlights other than a burnt bulb. Simplicity can be a good thing sometimes.
