the color mod for tsx projectors is putting 2 washers on each "nipple" on the bottom of the "halves" of the projector...so 4 washers per projector. real simple...
ive never seen tyc's up close...but yeah it probably is for the high beam.
once again, ive never messed with tyc's. if you have a stock headlight around, look at the lower corners and you'll see some little "boxes" on the outside...those are the vent holes. people always say they need to seal the crap out of the headlights. my stockers dont leak (as in: when its raining) but they fog up when the temp goes from like 40 degrees to 70 and humid, and especially vise versa.
ive drilled holes in the bottom of headlights due to fogging and even standing water. if there's water inside, they're leaking. if there's fog, they're condensating due to the moisture not being able to escape.
our headlights aren't water/air tight regardless of how much sealant is on them...i wish people would stop propagating this myth
the only totally sealed headlights ive dealt with were plymouth acclaim/dodge spirit 9004 headlights.
if you take off the ignitor (wire that attaches to the bulb) and look at the bulb, it'll have a + next to 85122. if not, its a regular 85122.
you want to see yellow...i have a heavily used 85122 non-plus bulb for testing...that thing is bad.
