Product Description

Kensun HID Xenon Headlight Conversion Kit

HID lights have a glass chamber of gas, replacing the filament of traditional halogen bulbs. The gas is ignited by a 23,000v charge and stays illuminated by a constant 12v source provided by a ballast which is connected directly to your battery.

Remarkably, HID lights are able to provide greater light output with much less power consumption. Studies show that a 35w HID lamp produces 3 times as much light than a 55w halogen bulb. Also, a halogen bulb uses a continuous power draw of 10-15 amps, while the HID system uses 20 amps for ignition, but then drops to a mere 3 amps during operation (i.e. up to 80% less power during use!).

In addition, the HID headlamp provides longer service life. With no filament to vibrate and fatigue, under normal conditions HID bulbs last roughly 10 times longer than halogen bulbs.

What is HID Color Temperature?

Color temperature is a characteristic of li ght that is sometimes mistaken as brightness, when it is more closely related to "cool" and "warm" tones of light. Color temperature is a measure in Degrees Kelvin of the hue of a light source, in this case the HID bulb. (The term color temperature actually refers to the color associated with the amount of heat needed to produce that color from an ideal black body.)

It is hard to describe HID colors accurately since many variables such as voltage, type of ballast and the environment can affect color output. Also, color perception is subjective. That said, here is a rough guide to Color Temperatures for HID bulbs:

• 3000K = Yellow
• 4300K = Bright white yellow tinge
• 5000K = Pure white
• 6000K = Bright white (some detect slight blue)
• 8000K = White with blue tinge
• 10000K = Light blue
• 12000K = Blue
• 15000K = Darker Blue (may appear violet)
• 20000K = Blue indigo
• 30000K = Indigo

Excellent-from delivery through installation
By jp5472
This product was even packaged greatly! It was a very simple install process, with only a few minor issues one faces when custom mounting anything not designed to be OEM. I found the spots needed to mount the ballasts and the rest fell into place. Instructions and questions/troubleshooting sheet were excellent. Nothing looks or feels cheap or skimped on. Now after about 10 days of use, satisfaction continues.

**Update** - Just wanted to add that I had an issue with one of the lights blinking continuously. I contacted the company and they sent out a new ballast right away solving the issue.

Excellent... That pretty much sums it up
By K. Williams
After reading several reviews, I decided to make the leap into H.I.D. headlights with the Kensun conversion kit. I have a Tundra, and I have been running 100W halogen lights to get better visibility at night. The 100W halogens ended up baking my sockets and the wiring to my headlights... So, since I was going to have to work on it anyway, I decided to finally get some H.I.D. bulbs.

The kit was very simple to install, not much in the way of directions but really it was very adequate. They are dead simple to install, I could have done it in 15 minutes or so if it weren't for a couple of things that are specific to my Tundra. The truck came with shields for the stock bulbs, and these light ran into them. They were a bit of a hassle to get out, since the headlight assembly is completely glued tight and they are a little bigger than the hole for the bulb to go through. I also had to spend a few minutes figuring out how to put the stock rubber boot on over these bulb s. The bulbs had a twist lock bayonet style mount to lock the bulb to the big part in back for the high beam, and I had to work the boot on but it's all good now.

The lights didn't work at first, and I spent a few minutes figuring out what was wrong. The directions said to reverse the polarity, but it could have been more clear if they had said to reverse the polarity where the harness plugs into the ballast. The ballast are marked "+" and "-" right on the plug housing... But I put a volt meter on the harness and there was no power coming out of it. Then I ran jumpers to the ballasts directly, and both lights lit up. It turned out that the relay assembly (What they call a "Control Box" in the directions) was not working at all. I called the number at their web site, [...]. I left a message since they are closed on Friday and Saturday.

They called back and got my amazon order number and said they'd ship me a replacement. I told them I would need the wir ing harness too, since I needed to have headlights in my truck and I cut the harness to wire in a Bosch relay so I would have low beams at least. They said no problem.

A couple of days later the new harness/relay arrived, and I swapped it out. Honestly, though, I don't know if I really needed the HID high beams... (Several reviewers said to be sure you ordered the bi-xenon kit with HID low and high beams.) These lights are so bright on low beam it borders on ridiculous! They look like they put out more than three times the light of the 100W halogen bulbs... If I bend over and look right into the headlights from 20 feet in front of the truck I am temporarily blind for 20 or 30 seconds... These things are freaking bright!

When you flip the high beams, it's instantaneous... I was wondering if there might be a slight delay, because they actually actuate a solenoid type of assembly in the back of the bulb to reposition the bulb. No delay at all... And on hig h beam my truck lights up the street all the way down to the end of the block... I'll probably not use the high beams much, but when I'm driving up in the mountains at night, it will be really, really nice to have these things.

When they fire up, you can hear a slight buzzing from the ballasts when you are standing next to the truck with the hood up and the engine not running, but there is absolutely no electrical noise. I have the Toyota high end stereo for the truck, and also a satellite XM radio, and an Ipod connector... No interference at all with the stereo system.

I am planning on replacing the headlights in two more cars with these. I don't know how I went so long without putting in the HID bulbs, but now I am a huge fan! I just have to do it when my wife is not around, so I don't get yelled at... :-) (She has great night vision, and she doesn't see why I wanted brighter headlights... )

Bulbs and ballasts are amazing, but wiring harnesses feel cheap.

Kensun HID Xenon Conversion Kit "All Bulb Sizes and Colors" with Premium Ballasts - 9004 (HB1) Bi-Xenon - 8000k
This is my second purchase of a Kensun HID Conversion kit. I had a great experience with the first kit for a 2001 Nissan Sentra, so, I decided to get another Kensun kit to upgrade a '95 Dodge Ram Van. Second kit configuration is 9004 Bi-Xenon 6000k. The light quality is amazing! However, I can't really rate the performance/durability of this kit yet as it is brand new and I haven't driven with them long enough. I would have rated this a 5-Star, but doing a comparison with the first kit (9007 HID Bi-Xenon 6000k), I'm quite disappointed at the quality of the wiring harnesses. The wires seem very flimsy and thin. The Control Unit, bottom half where the wiring harness is connected in, is covered with a thin rubber casing that feels loose and does very little for weather protection like water. The first kit did cost $20 more and the wires were very sturdy, bette r insulated, stronger gauge, and better sealed Control Unit. Honestly, I like quality and wouldn't mind the extra cost for better wires, if it was an available option.
