I used to do all my driving at night, so I have always had good spotlights
I have heard of people taking their spotties off to help with the cooling etc - get smaller spotlights with a greater power
instead of 35W or 55W, get 75W HID, but in a smaller spottie - 3" instead of 7"/8"
100W Halogen bulb puts out the same light as a 35W HID
130W Halogen bulb puts out the same light as a 40W HID
8W LED bulb puts out the same light as a 100W Halogen (but not concentrated)
as
@Sammy D said, get a LED Light Bar
except they must be in pairs as per ADR's - and the Law
lots of people getting picked up lately for having an LED Light Bar - singular
on the roof rack
on the top of the Bull Bar
below the front Bull Bar
etc
(or putting black tape in the middle to make it look like 2 Light Bars)
one of the reasons that 56" light bars are so cheap
you cannot legally fit them to your car / 4wd / truck
below is where you CAN fit LED Light Bars in WA
