I had HID in both the crewman and VE Calais. Loved them. The ones that had the drivers in the dust cover. Remove the factory dust cover and screw the HID driver in as the dust cover. All plug and play. Country driving at night was stress free. As for glare, it was no different as any other car. A few times I drove in front of the other car (wife driving). Never bothered me at all.
High beam was a bit annoying in the Crewman. SS lights use the same dust covers as up spec VE. I had used VE HID kits in them. I hadn’t yet done the high beam wiring mod, so when high beam went on, the road would go dim for a few seconds while the highbeam bulbs warmed up. Once the low beams stayed on it wasn’t such a big deal.
