After messing with various lights for a few decade I can honestly say a proper LED auxiliary light or 2 would be my best choice in the future. I presently have 2 LED driving lights on the Honda but they are overkill when pulling a maximum of 70 watts. 20 watts would likely be more than adequate in most cases after dark.
The GZ can easily support a 20 watt load for a couple 10 watt LED driving lights.
A word of caution for those thinking of really bright LED's on any vehicle. The light reflected back from road signs can and will blind you in many cases. Luckily my LED's can vary the power draw so I no longer go half blind with large overhead road signs.
Always use bright lights with discretion and don't blind others.
