Side-by-side comparisons

Left is HID / Right is Halogen. You can see the HID ballast wiring and the difference in lenses. Halogens appear clearer? Both lenses have ridges in the glass - so both are fresnel?

Differences in depth of the projector. HID is smaller.

Yeah but they range in price by a lot. Not sure of their differences. It would be cheap to test with the Acme projectors for $25 to $40 and an ebay HID kit for another $25. GC lense size is 2.5". https://www.theretrofitsource.com/hid-systems.html?___store=trsdefaultview

What would break and limit travel in the L/R adjustment? But still allows some adjustment, definitely not full range.
The edges of the projector around the lense can scratch against the inside of the shroud. I found out about this when adjusting L/R to get a more narrow beam.
