Default Thoughts on bugeye JDM STI and Dual Halo LED headlights?

So I'm considering getting either the HID JDM STI headlights or the Dual Halo LED ones. I'm assuming both will require a conversion from RHD to LHD since they are JDM. I've been looking into the JDM STI ones a lot, but couldn't find much info on the Dual Halos. Does anyone have the Dual Halos and know of any common issues or problems that they may have had? The ones I'm talking about are these

Also and pics of them at night? I can't seem to find any good ones.

The low beam projectors for those dual halo ones are a downgrade compared to the oem halogen reflectors. Without a proper retrofit, I'd stay away from them from a functional point of view.

However, the headlight housing dimensions (with respect to mounting points, horizontal & vertical level, low beam adjuster screws, etc.) are quite well made for an aftermarket at that price point. I've tested another aftermarket many years ago, the wrc replica (also sold in Japan under Zowie auto studio), and this new one is better in that regard.

With a little bit of proper HID projector retrofit, you can get great low & high beams out of this pair.

Okay so the dual halo headlights can be adjusted for LHD?
How much would a retrofit cost for these?
What part of the headlights are actually LEDs? just the 3 tiny bulbs?
How do the rings work, they light up with the halogen bulbs?

Thanks for your help

What do you mean by LHD? The vendor is in California, and it is set up for North America already. I'm assuming you're asking because you're planning on using the low beam projectors as is. The low beam projectors itself has a shield that you can flip for LHD-RHD adjustment, but I hope I can convince you not to use the projectors provided.

Having seen beam output pictures by users, and having tested the halogen H1 projectors that came with mine (before retrofit), I don't believe that the beam output picture in the product page you linked is the same as what you actually see in person. (perhaps it is possible to look like that in pictures without photoshopping; under certain camera settings)

Taking the picture in that product page at face value, notice that the pattern is more like a pencil beam in terms of angle of coverage, yet short like a foglight in terms of distance lighting. Having most of the light thrown right in front of the car is not what a low beam should do.

I don't know what the going price for a retrofit is, if you have someone else do it for you. However, you can always go the DIY route (like I did). There are some DIY retrofit threads here in Nasioc. There are many general & useful information in HID specific forums, like HID planet. Here's my build thread (link).

DIY options, in no particular order of preference:
  • Plug-n-play HID kit: bad idea, and no better than the one already included in that set. Not a retrofit!, but sadly an option that many people take due to its price and ease of installation.
  • No-name biXenon projector + ballast + HID capsule + harness: can't guarantee consistent product quality and long term durability, and might work with some heavy modification to cover its deficiencies. Might cost less than $100 altogether.
  • Previously owned OEM projectors + previously owned OEM ballasts + new OEM HID capsules + custom harness: If you get great projectors like from LS640, RX330, S2000 (low beam only), TSX, ..., and 4300K Phillips 85122 capsules, you can get excellent output. Cost range depends on the OEM projectors used; could cost north of $500. Might need to pot the ballast (to waterproof it).
  • Aftermarket complete retrofit kit from a reputable vendor. For example, The Retrofit Source sells a variety of these kits, that include projectors, HID capsules, ballast, and harness. They run from ~280 for a compact (i.e. easier to DIY) unit with much better output than the plug-and-play kt included in the product you linked above as well as the oem bugeye halogens; to ~$500 for a mostly OEM component set.

HID planet has a lot of threads comparing the outputs of many projectors, the dimension of these projectors (for fitment), ballast, and HID capsules.

The 3 city lights as well as the halo rings are lit by LEDs. The halo rings are quite dim imho, and was the first one I discarded. Each halo is lit by 2 opposing smd LEDs, diffused by the acrylic halo rings.

The city lights are 3 LEDs nested around reflectors. With a bit of modification, the city lights are actually usable in daytime as a mild DRL. Here are a few pictures to give you an idea of the 3 LEDs. I compared the LEDs as is (top LED) vs. with LED diffuser lens (middle & bottom LEDs). The bare LEDs have a very narrow angle, making its apparent brightness drop dramatically when viewed slightly off axis. Diffusers help make up for this. The pictures are taken at different camera settings, mostly with very short exposure (looks very dark but makes it easier to see hotspots with more resolution).

Very informative, I didnt notice those headlights were in California. I assumed all of the dual halos were JDM. I think I will just stick with the JDM STI headlights then. Thanks for your help!

"JDM" is an overused marketing phrase.

If you start from a JDM STi pair, make sure the RHD to LHD conversion shield is well made. I don't have first hand experience, but recall reading someone buying a less than stellar conversion shield. Might as well replace the low beam projectors with s2000 or TL oems. The size should be somewhat similar, so a DIY is not out of the question.

TL (bixenon, older generation vehicle) will never fit. TL (single xenon, more recent year vehicles) will, but you would pay a premium over the TSX which is basically the same projector and is more easily found online.

Good point. I should've said s2000 or TL low beams then.
