This thread is for discussion of the
SKBOWE PWM filter, a plug-and-play error harness that I developed to help the P1 community with HID retrofits. If you have a question that's not related to the SKBOWE, please see if it fits in one of the other HID threads (above) before posting here or starting a new one.
Lets face it, the OEM halogen headlights in our cars suck. We should all know by now
the issues with HID retrofits, and that the
DIY solution is not trivial since it takes some soldering and hacks up the CEM harness. I have been PMed dozens of times over the years asking for a better way...
So... I found something really sweet

If you are interested in a commercial, plug-and-play (no cut wires!) solution that was designed specifically for Volvo P1 cars (S40, V50, C30, C70) check out:

Useful Snip
For those of you looking for projectors, I put together a reference sheet to help you identify compatible Bosch AL 3-inch "E46" projectors in auctions or at salvage yards:
See the full resolution PDF here:
https://www.theeshadow.com/files/volvo/e46/guide/al_projector_guide_v1_web.pdf
You want to look for "Gen 2" projectors, they have the best optics and the wiring is simple. Gen 1 requires a
solenoid controller for bi-xenon functionality. All projectors with black plastic rings will fit D2S, the ones with octagon-shaped bulb holders might need a simple modification (bending a small tab) to allow them to take D2S bulbs.
If junkyard hunting and eBay stalking aren't your thing, Nick has been nice enough to hold a few for us:
matched sets of gen 2 projectors... PM if you're interested.
Here are some
projector beam patterns:
