I have changed the dip to HID and the main beam to Osram Night Breaker plus £17:49 Ebay for 2 lamps.
Due to the HID lights taking a few seconds to get to full beam brightness I stuck to filament lamp Osram night breakers.
The HID choke can be fitted under the side pod and by cutting the right size hole in the lamp rear cover the HID seal can be used to seal off the light from moisture.
Much better than the standard lights.
See and be seen.
