Changing the halogen headlights to xenon - Night and Day !

Why ?

•  Factory installed low beam bulbs in headlights were awful, tried changing better bulbs from auto zone and other places, but in the end they were still halogen
• Little bit spare time on weekends and creative juices...

Precautions & Needed Items

•  Remove your apple watch before working
• Have a 6 pack of beer handy
• Make sure you have a helper (I needed someone to use a flashlight, as I don't have a good work light)
• HID Kit (there are multiple ones on amazon and ebay). 
• I bought a Kensun kit with 6K intensity  (mainly because they were very helpful in determining what I needed and whether it will work in my vehicle or not...)
• I also bought a warning canceller kit to go along with the HID kit ('cos I was installing it in a mercedez.... )
• I also bought a 1 inch drill bit (as I knew that i'll have to drill a hole in the headlamp dust cover after talking to the Kensun folks)
• Wear gloves
• Finally, you need Patience !

Instructions

• Pop out the dust cover 
• Identify your low beam bulbs
• Detach the 2 wires  to the bulb and pop the bulb out carefully.
• Assemble the HID  xenon kit. 
• The instructions with each kit are self explanatory and you basically have to connect the wires to each part in the harness and bulb.
• I had to insert the  warning canceller cable in between
• There are two separate assemblies for the driver's and passenger's side
•  Drill a 1 inch hole in the dust cap
• Before
  
• After
  
• Carefully, remove the bulb and insert into the dust cover assembly ( you just need the bulb and the wire connector to be inside the dust cover, all other cables will be outside the dust cover - towards the engine)
  
  
• Carefully plug the bulb in, align it..
• Test it... In my case, I had the polarities on the bulb reversed, as Mercedez  used a yellow and a brown for the wire colors, and I had to figure out that brown was negative and yellow was positive.. and Mercedez warning console warned me right away....
  
  
  
  
  
   
  
  
  
  
  
• As you can see, I tested one side before first, See the huge night and day difference !
• Snap the dust cover back in and repeat steps for the other side
• Mount he HID harness and kit inside the engine, make sure you don't mount or attach to moving or heated parts.

Don't be afraid of trying this, in the worst case, you can always take it to the dealer, if you screw up !
