Be aware that you might loose the hi/lo option, but I know that with a nicely aimed HID on lo beam, you'll hardly need the hi beam. Some make HIDs with an integrated halogen filament, but as far as I've read, those are only to pass inspection. There are some kits that move the lamp up/down for hi/lo, but I imagine those have to be too large for our cars?Anyone install HID headlights in their '67-'69 Camaro? I'm considering getting them. I'd like to know what brand and part numbers you've used, and your feedback on them. Thanks.
