Yep, single bulb but dual filament. That's why Plug and Play bulbs don't work great in our application. But does your Spyder lights use a different bulb setup? Not sure if your high and low beams both come out of the projector up in there.
@GreatAvalon, I'm not sure. I know I can run a H9 HID but there were bulbs already in these.
My stock bulbs went to you.
I assume you can run stock size bulbs in these as no where does it say anything about new ones.
Hmm...H9 is definitely a different bulb than the stock bulb size, probably not able to run H4 in those headlights.
But I just took a look at those headlights and they don't have a separate high beam bulb, so I would imagine the projector has a moving shield that opens up when you click your high beams on. Similar to bi-xenon projectors. Easy way to tell is have someone turn your high beams on and place your head near the headlight and see if you can hear a mechinal "click" sound.
But yea, so if those new headlights use H9, then that is a single filament bulb. There's no separate high beam bulb (it appears to me at least using google images), so that means 2 things: 1) a shield inside the projector moves allowing the light beam to go high in high beam mode, and 2) a H9 HID bulb should help low beam and high beam.
Only way it's different is if there was 2 bulbs plugged in to the projector. But that's pretty doubtful IMO.
Has anyone tried the new GTR Gen3 LED bulbs? The design is definitely different, and I am curious to know how they work in terms of High Beam/Low Beam comparison. The Gen 2 bulbs didn't seem to have too much of a difference between the high and low beams.
