...But not improved enough.
Baked my headlights and opened up the low beam housing to install the TSX-R projector lenses mentioned in
this thread, though I know many have gone beyond to putting in full bi-xenon HID projectors like the Mini H1 or 3" D2S. I wasn't ready for that investment so just stuck with the lens swap for now. Went fairly smoothly and with solid results.
TSX-R lens (left) is much clearer and focused compared to OEM. It is slightly smaller, which required a dab of glue onto the the paper spacers to prevent movement.
Best focus was with the OEM spacer (larger ring) and 3 TRS paper spacers (which are a bit smaller). Centered them all and glued together for stability. Put a dab of glue between them and the lens also. This prevents any movement of the lens since the OEM spacer fits the factory projector ring perfectly. Can remove the whole spacer + lens setup in the future if ever needed. Not sure why that would be, but keeping things as reversible as possible is important in my builds. In a move exactly opposite of that, I covered the "squirrel finder" holes with JB weld to prevent blinding others with the new HID output.
OEM lens bottom, TSX-R lens top. So much sharper.
Both TSX-R lenses but no paper spacers on the bottom.
Final beam pattern (leveled them just after this pic). Still has a mild hotspot that I centered a close to the cutoff as possible but so, so much better than the stock halogens. I suspect someday I'll want to upgrade to a Bi-xenon fully retrofitted projector, but for now this is great. Plus, if I never have to remove those damned fiberglass trim pieces to get to the headlights again, it will be too soon (cracked them both on removal, now glued back together with some tiny fault lines as a reminder of this project).
