Don't put HID or LED bulbs in reflectors, glare and the output isn't good.
If you want modern style lighting, no choice but to retrofit (should cost below $1,000 all up if you do it yourself). Series 3 GT-R projector headlights are super expensive.
The outer plastic lens must be clear, any hazing/yellowing dramatically reduces output.
Alternatively if you're doing country driving, can try a light bar for high beam?
