I believe I saw your post in the FB owner's group - if so, you have the Spec-D aftermarket assemblies (or possibly a copy of them), which do have an endless litany of build quality complaints - including that they use even worse projector lenses than the OEM projectors, and that's saying something because the OEM projector lenses are also pretty bad - plastic lenses are not great for focusing light!2016 VT and I am wanting to upgrade my headlights. Previous owner had replaced the headlights with some cheap aftermarket ones (Junyan I belive they are called) and the beam pattern is horrible. Way too many dead spots in the pattern and I drive alot in the dark. What do you guys recommend for headlight replacement? I have talked to someone about some custom ones but I have also looked at the KDM ones offered by SoCal. I just want to be able to actually see when I'm driving lol. TIA
Unfortunately the KDM-spec headlight assemblies use the same plastic projector lens as the US-spec OEM projector headlight assemblies, so you're not going to get any better beam pattern from the KDM version than you will from the US version - the only real way to get a better beam pattern is to open them up and projector swap to a good Morimoto or one of the other reputable brands.
That said, the OEM projector headlights -while they may not look as cool as the Spec-Ds from the outside- are certainly better quality in general, and before I swapped my assemblies I drove for well over a year with no real complaints on US-spec OEM projector headlights with good H11B LED low beam lamps (BPS Lighting UltraV H11B) and good H7 LED high beams (Lasfit H7 L1 Plus). If you're looking to save money, pick up a set of used OEM projector headlights, swap to LED lamps, and make sure to adjust them properly and you'll at least have a better experience with them than you're having with your Spec-D/Spec-D copies.
Here's a photo of the low-beam pattern from US-spec OEM projector headlight assemblies with the BPS UltraV H11B LEDs. Doesn't hold a candle to my current setup, but it wasn't bad:
Current low-beam pattern with KDM-spec housings that have been fully opened up, painted, and projector-swapped to Morimoto HID projectors + Morimoto XB-35 5000K HID kit:
And the high-beam reflectors were also matched to the low-beam projectors while the assemblies were opened up, so low+high beam pattern (still running Lasfit H7 L1 Plus LEDs in the high beam position) is now:
Definitely worthwhile to do or have done by someone, as there's no longer any thought of "outrunning" the headlights, which I always felt slightly uncomfortable about on the OEM projector setup, but on the other hand it's a PITA to do, so if you're not committed to doing it or having it done, stick with OEM (US or KDM, doesn't matter) projector headlight assemblies and good LED lamps. It is worth noting that it is not generally advisable to convert to HID lamps without also opening up your headlights and swapping your projector lenses, as the high heat of HID has a very high likelihood of melting the plastic OEM projector lens. If you want to go HID and have it be reliable, do it right - otherwise stick with LED or halogen lamps.
