Make you realising you have lights on your rig intead of candles, especially when driving in rainy nights
Those kits are plug & play, using stock harness. Take good care of polarities : if the ballast doesn't start, just rotate the plug 180°, reconnect and it will fire.
Pay special attention to have good grounds too.
I had low & high beam kits on my rig. A true night and day difference.
I have one H4 kit on my Zuki too.
The only problem on my Chevy was when switching from low to high. A HID bulb needs about 10 seconds to warm and be fully functional.
So, when you go from low to high, you're blind during 10 seconds. Very funny ):h
The solution was the Hi/Low beam kit from M. Tail Light which keep your low beam on, while you're swaping to High beam. 4 HID bulbs on at the same time : sun on the road :thumbsup:
Prefer the kits with slim ballasts. They are a bit more pricey than stock ones, but they light bulbs faster...
8000°K produce a nice blueish light, but remember, the more blue you go, the more blind you will be under rainy conditions.
From my own experience, the range between 4300°K (sun light) to 6000°K (polar white) offer the best performance.
Average, a 35W HID kit will produce about the same amount of light than stock bulbs, while being a lot more bright and comfortable, a 55W HID kit will produce as much as 115~130W stock bulbs, and always very clear.
To get an idea of what HID can offer you, have a look at these new Audi, BMW or Range Rover lights...
