For very little extra you can go full HIDs. The difference is absolutly stunning.
And also illegal and dangerous.
Bollocks! There is nothing illegal or dangerous about HIDs.
You will not fail an MOT for having HIDS, you will fail for having badly adjusted lights because badly adjusted lights are dangerous.
Fitting HIDS greatly increases the quantity AND the quality of light you are putting out. The makes it much easier for other road users to see you, and much harder for them to ignore you, particularly in daytime and dusk conditions. That alone significantly improves your safety.
The improved quantity and quality of light makes it much easier for you to see in dusk and dark conditions, that significantly improves your safety, and that of other road users such as cyclists and pedestrians. (Dayglo and reflective materials are visible up to three times further away!)
If you are getting flashed, it is because your headlights are not adjusted correctly. Regardless of whether they are regular, improved, or HID bulbs, if they are not adjusted correctly then they are not pointing in the right direction and that makes it harder for you to see, and for others to see you.
Fitting HID bulbs has been the single greatest improvement to safety I have ever made to any bike I have ever owned, but you don't have to believe me. Get a cheap and nasty chinese kit and try them for yourself. You could fit them in an hour and if you don't like them, you can completely remove them in half that. I recommend 5000K colour temperature as being sunlight white. 6000K and higher has an increasingly blue tint which apeals to the kiddies in modded cars but doesn't actually help you see better. The best bulbs for the Fazer are H4-3 as this means you keep normal full beam function.
